Keeping electrical woes at bay

Regular maintenance involves more than just periodically checking the coolant level and replacing a split wiper blade. Keeping a vehicle in a roadworthy condition means keeping an eye on everything that can deteriorate and acting in good time to prevent breakdowns and failures.

The vehicle’s electrical system is no exception to this, as a lot of breakdowns occur due to electrical failures. Timely intervention and a spot of maintenance can go a long way to prolonging the service life of components and ensuring everything is kept in good working order.

Some jobs are the ‘poor cousins’ when it comes to vehicle maintenance and simply don’t get as much attention as others. The maintenance of vehicle electrics is a job that falls under the radar more often than not. A handful of tools is all you need to keep the electrical components functioning as they should, which is necessary as, over time, connections get dirty and contacts no longer conduct as they should.

Is it really necessary to check and clean the car’s electrical components?

The straightforward answer is yes. Contacts that are exposed to the elements, such as battery terminals, are predestined to suffer from an accumulation of dirt, grime and chemical deposits, but also ignition components and earth leads can succumb too. The problems often become most noticeable during the winter i.e., when the battery and electrical system are put under the greatest strain.

The battery terminals have to fight on several fronts simultaneously. The environment in the engine bay not being a friendly one, with components having to deal with the effects of heat, cold, moisture, fumes, as well as gasses emitted by the battery which attack the terminals. It is no wonder then that electrical connections suffer under this continued attack.

When diagnosing poor engine performance, the first thing that is checked is rarely the battery or the charging system. Poor battery condition, an underperforming charging system or inadequate terminal connection can, however, cause rough idling and intermittent loss of power or engine performance. Problems can arise due to inadequate or inconsistent voltage supply in the vehicle’s electrical system. If the condition of electrical connections is allowed to deteriorate further, this could even result in a breakdown at the roadside.

The risk of a breakdown or a system malfunctioning can be reduced significantly by cleaning electrical components regularly to ensure the vehicle systems continue to perform as intended. The battery terminals are particularly important because the power needs to get to and from the battery.

A critical part of the circuit are the earth straps connected to the vehicle body. Earth straps must be kept clean to maintain good contact to the vehicle body, otherwise spurious signals can be created causing the (MIL) check engine light or driver assistance system lights, such as ABS warning, to illuminate.

Funnily enough, you can often tell when a car’s earth contacts are no longer functioning properly, as you will have almost certainly seen the phenomenon from time to time.

If the earth connection on a car’s rear lights is poor you often see, for example, the sidelights come on dimly when the driver presses the brake, instead of the brake lights. The rear light cluster is not earthed sufficiently and the electricity flows through the rear light cluster finding the path of lowest resistance to earth, which is often through another bulb e.g., the indicator or sidelight light bulbs.

How can you tell when electrical contacts need cleaning?

Dirt and corrosion can cause electrical faults and electrical faults are notoriously difficult to trace. Often it is easy to take the symptoms at face value and go straight to a component when it is really an electrical contact that is the source of the trouble. Here are a few tell-tale signs which indicate that the electrics might need checking and cleaning:

  • A warning light on the dashboard

Electrical faults, especially earth connections, often cause warning lights to appear on the dashboard, due to signal interference, even if the actual component is fine. First check and clean the contacts, only if the fault does not go away should you check an individual component for any obvious faults. Often simple faults like dirty pins or deposits on the earth strap are the reason for the disco on the dashboard, not component failure.

For instance, the use of copper grease on the brakes can affect the ABS sensor signal and bring on the warning light for the same reason that dirt ingress in a multiplug or a sensor failure will i.e., interruption of the signal. This is why modern brakes need a ceramic lubricant.

  • An intermittent dip in performance

The alternator might not be charging the battery properly, which could be the result of dirty battery terminals, a defective battery or a worn-out alternator. By keeping the battery connections clean at all times, you automatically reduce the chances of engine problems due to avoidable electrical faults.

  • Headlights dim

If the headlights do not light up the road as they should, there could be a connection problem. Maybe the headlights dim slightly when you switch on the heated rear window etc? If the headlights dim temporarily that’s okay, but if the headlights don’t recover fully this could indicate a connection problem, such as dirty pins in the multi-plug or a bad earth connection.

  • Electric windows not operating as usual

Slow window wind down etc., can be caused by dirty or corroded connections. Check connections at this point to find the source of the problem before a loss of function occurs.

How to clean the electrics with contact cleaner

Do you feel uneasy at the prospect of cleaning electrical parts? Well, there really is no need to worry, however, you should exercise caution. Access is the first hurdle, as a lot of wiring and connectors are hidden behind covers and often located in difficult to reach areas. However, most parts are normally easy enough to locate and access if you check the manual first.

One risk you can easily avoid is using the wrong cleaning method. A lot of people reach for a screwdriver, abrasives or some form of metal tool to clean off dirt and corrosion. The trouble with this method is that it also damages the surface of the connector, which is counterproductive and can do more harm than good, often leading to increased corrosion or lower conductivity.

Try to resist the temptation to reach for a screwdriver or the like and instead grab a can of contact cleaner. The condition of the contacts will be better afterwards and you won’t need to clean them again so soon either, because contact cleaner causes no mechanical damage and, after spraying, the contacts are coated with a corrosion inhibiting film.

Contact Clean+ c32 is made specifically for the job and is safe for electrical contacts. The spray is formulated to clean away grease, oil and dirt, and re-establish conductivity rapidly. It has a powerful cleaning action, getting to work instantly, removing stubborn dirt and corrosion and leaving behind a clean contact but no residue.

When the needle of the temperature gauge starts heading towards the red zone you know that it is time to act. Getting stuck in traffic can easily lead to the engine overheating. If you are lucky, the engine will not actually boil over this time but maybe the next! If the cooling system overheating is due to a problem that gets progressively worse, you tend not to notice that something is wrong until it is already too late.
Overheating can usually be predicted well in advance because the temperature gauge has probably been showing a raised temperature for a while. Most of the time, however, drivers only take action when a breakdown is imminent or actually occurs.

How can BIZOL Radiator Clean+ r70 cure the problem?

The cooling system gets less efficient as deposits gradually form in the coolant pump, radiator channels and waterways. Corrosion, sludge, scale and other deposits also form, unseen, inside the heater matrix, engine block etc, lowering the system’s cooling system efficiency bit by bit. BIZOL Radiator Clean r70 is a cost-effective way of increasing cooling system efficiency by simply eradicating unwanted contaminants and deposits.

Treating the cooling system with BIZOL Radiator Clean+ r70 is far less expensive and time-consuming than replacing components. If, however, you have to replace a component anyway, simply pour in a tin of radiator clean to prepare the cooling system for the new component and restore its efficiency.

How does BIZOL Radiator Clean+ r70 work?

BIZOL Radiator Clean+ r70 resets the cooling system by removing scale and rust particles, then neutralises and flushes out the harmful deposits, removing any rust, sludge and limescale in one operation.

BIZOL Radiator Clean+ r70 and its benefits:

  • it removes rust, limescale and deposits thoroughly and reliably
  • it is not aggressive to gaskets, metal or rubber parts
  • it is phosphate-free and EDTA-free and neither contains chemicals that contaminate the watercourse nor forms such compounds with other chemicals.
  • it is free of aggressive acids or alkalis

How do I get started?

It could not be easier, just remove the pressure cap and pour the contents of the tin into the radiator or header tank.

Start the engine and allow it to idle for 20 minutes to get the coolant circulating properly and so that the additive mixes fully with the coolant and reaches all parts of the cooling system. BIZOL Radiator Clean+ r70 gets to work, cleaning the channels in the radiator, the coolant pump and waterways in the engine block and cylinder head.

Once the thermostat has opened and the coolant has been able to circulate fully (for approximately 10 minutes) switch off the engine. Allow the cooling system to cool down fully before proceeding. When the cooling system has cooled down, undo the pressure cap and drain the coolant.

Make sure that all of the sludge and deposits have been drained from the system, flushing the radiator with fresh water as necessary. Once the corrosion, sludge, scale have been thoroughly flushed out of the system, reattach the bottom radiator hose.

All that’s left to do now is refill the cooling system with fresh coolant and bleed the system.

Do fuel systems really need to be cleaned?

You might be forgiven for thinking fuel systems no longer need any attention, after all, with modern refining technology fuels have never been so clean. The fuel system, however, is not a sealed system, nor is the engine itself. So, no matter how high quality the fuel is, deposits, gum and oxidisation build up over time. Oddly enough, modern fuels tend to absorb more moisture than older, conventional fuels.

As fuel deteriorates, residues and oxidation take their toll on the fuel system, affecting performance and causing damage to fuel system components. In figure 1 and figure 2 you can see the degree to which fuel degrades. The test shows how petroleum spirit is affected, even promoting oxidation.


Figure 1 – Beginning of fuel stabiliser test

Figure 2 – End of fuel stabiliser test

Choked fuel system components

Varnish and gum build up in the fuel lines, fuel pump, fuel injectors and carbon accumulates on the inlet valves. The gradual deterioration of parts delivering the fuel-air mixture, means that the components no longer function as they were designed to. The easiest way of remedying the problem – without going to the expense and inconvenience of removing and cleaning fuel system components – is to use a tin of BIZOL Gasoline System Clean+ g80 or for diesels BIZOL Diesel System Clean+ d60.

Noise from the engine

General rattles, timing chain chatter and other noises from the engine can be caused by poor fuelling, due to rough running behaviour. Deposits also restrict the supply of fuel and negatively affect the injector spray pattern, just like a shower head when the jets are blocked by limescale. The fuel injectors get clogged by fine deposits limiting the flow of fuel.

Changes to the spray pattern affect fuel atomisation and injection duration, which, in turn, means that the engine management system has to increase injector duration to compensate. Poor fuel atomisation reduces combustion efficiency, increasing fuel consumption and reducing amount of power at your disposal. The longer the problem is left untreated, the greater the effect on the fuel system and engine.

One application of BIZOL Gasoline System Clean+ g80 already dissolves many of the accumulated deposits, but it is advised to use the treatment regularly to keep trouble at bay.

Figure 3 – before and after treatment

If left unchecked a build-up of deposits will, at first, cause a gradual loss of power. Many of the signs that a problem is developing are often not recognised or ignored. And that is the reason why cleaning away the deposits is essential, as prevention is better than cure.

Problems caused by a build-up of deposits include:

  • loss of performance
  • increased fuel consumption
  • increased emissions
  • poor starting and idling behaviour
  • emissions test failure
  • poor driveability
  • erratic idling
  • poor throttle response

BIZOL Fuel System Cleaners

BIZOL System Clean+ g80 and BIZOL System Clean+ d60 are compatible with all commercially-available fuels and provide the following benefits:

  • restore performance
  • remove deposits from the fuel system
  • remove combustion products from the engine
  • prepare the engine for the next oil change
  • can reduce abnormal engine noise
  • restore oil flow and extends engine life
  • restore the function of critical components, e.g.:
    fuel pump
    injectors
    inlet valves
    fuel lines

Do modern engines really need friction modifiers?

You might be forgiven for thinking that with the advent of high-tech oils and advances in materials and engine technology, the need for friction modifiers was a thing of the past. Surprisingly, the need for friction modifiers is actually increasing, not decreasing.

Emissions standards and fuel economy requirements are getting ever more stringent. Tighter engineering tolerances and increased demands placed on lubricants means that engine oils are required to fulfil ever greater demands, year after year. The diagram in figure 1 shows the trade-offs made when formulating oils, for instance, between fuel economy and wear.


Figure 1 Specification requirement for ACEA A5/B5 engine oil

Despite incredibly fine machining tolerances, in figure 2 you can see, under magnification, the roughness and unevenness of seemingly polished metal surfaces. When rough metal surfaces rub against each other, the result is friction. Any friction that is created uses up energy and is a drag on performance. The drag created by friction means that the energy which has been extracted from the fuel is wasted by turning it into heat, instead of into movement. Figure 1 illustrates that need to improve fuel economy has an effect on oil specifications and thus oil formulation.


Figure 2 View of two sliding surfaces under magnification

Friction modifier technology is constantly evolving to keep pace with engine requirements. The majority of motor manufacturers have recognised that the most effective way to improve fuel economy is to use lower viscosity lubricants. The trouble with this approach, however, is that there is a point where the viscosity is so low that the lubrication film starts to become unstable under certain conditions. The proliferation of ultra-low viscosity oils in modern engines actually necessitates the use of friction modifiers to reduce friction whilst maintaining a stable lubrication film.

To tackle this problem, we have developed BIZOL Friction Modifier+ o94, which “hardens” the metal surface chemically, forming a slippery, protective layer on the load-bearing surfaces, building up chemically active nano-structures to improve performance and lower fuel consumption.

High-tech approach

Advances in nanotechnology mean that it has been possible to create a friction modifier with active agents so fine that they remain suspended in the oil until the point at which they form a film on the surfaces inside the engine. The chemically-active molecular nano film adds an additional layer to the lubricating film, thereby reducing friction. And because our solution forms such a stable suspension, we can promise you that there is no danger of solids settling or clogging oilways and filters. A clean engine means clean combustion, which, in turn, delivers optimum performance and improved fuel efficiency.

NANO technology refers to particles from a single atom to a structure size of 100 nanometres (nm). Using this technology means that the molecules can get into even the smallest irregularities in metal surfaces. Nano materials are produced chemically (using the “bottom-up” method), building up selected molecules.

The advantages of using nano-additives are their high-temperature thermal stability and ability to react with the surface without an induction period, an important advantage when compared to conventional lubricant additives.

Product benefits at a glance

  • highly effective at reducing friction and wear
  • optimal addition to the existing lubrication film
  • stable suspension, active agents (solids) do not settle or cause blockages
  • faster oil flow during cold-start phase and improved idling characteristics
  • prevents performance loss
  • reduces fuel consumption and thus CO2 emissions

Our newest product – BIZOL Friction Modifier+ o94, also features nanotechnology. Learn more about it here: https://www.bizol.com/products/full-product-range/additives/#bizol-friction-modifier-plus-o94-new

The short answer is that the range of applications for copper grease is diminishing, which doesn’t render it obsolete but means that it is losing its relevance in the workshop.

Brake component lubricants are an inexpensive consumable used when replacing brake parts. A good brake grease is integral to correct brake system operation and can make a significant contribution to safety. More often than not, though, the lubricant doesn’t get a second thought because its use is so ubiquitous. Mechanics need to understand why copper grease has fallen out of favour when it comes to modern braking systems. We will demonstrate why the use of conventional copper‑based greases can actually have a negative effect on the operation and performance of modern braking systems.

Garage professionals will agree that performing repairs and carrying out component replacement on the braking system is of critical importance to vehicle safety and why brake service must not be rushed.

So, after taking all that time and doing a thorough job, what could be worse than a customer returning with a complaint, saying that the freshly serviced brakes are squealing or they are experiencing judder through the brake pedal? Despite doing a meticulous job, i.e. preparing all of the mating surfaces and components thoroughly etc, the brakes do not perform as intended. But, if quality components have been used and all service instructions followed, what has caused the problem?

Well, the answer could be something as seemingly benign as the choice of grease applied to the components or even the condition of the grease. An open tin of copper grease lying around on the bench, ready for the next brake pad change is a common enough sight in many workshops, but it is a potential problem because the grease is exposed to the elements. If grease gets contaminated with airborne dirt and moisture, the lubricant will become ineffective. Inclusions trapped in the grease possibly even preventing proper seating of the brake components.

The main reason for copper grease falling out of favour, however, is because it can affect the vehicle’s ABS, ESP and EPB systems. Braking systems or driver assistance systems are highly sophisticated these days and with every year that passes, more electronics are being used in vehicle braking systems. Electronic braking systems utilise extremely low voltage signals generated in the sensors. The low-voltage signals are easily disrupted and this is why using copper grease is a problem. Copper is conductive and its presence in and around the braking system can interfere with the Hall-effect sensors used in the system electronics.

If a wheel sensor signal is disrupted, the control unit interprets that as a failure and will switch on dashboard warning lights, possibly even causing a wheel to lock up under braking.

The simplest way to avoid problems like this is to make sure that you’re using the right grease for the right application, which, in the case of vehicles with ABS, ESP and EPB systems, is a copper-free product.

Copper-based products generally cannot withstand high temperatures. The lack of high-temperature stability can prevent the pads from moving freely due to drag and can also cause premature or uneven wear. Another disadvantage is that copper is known to promote galvanic corrosion. Galvanic corrosion can cause components to weld together because copper-based lubricants can accelerate the corrosion process. The environmental concerns are also a problem because copper grease does not break down efficiently, causing contamination of the soil and plant life, further adding to the list of negative traits.

The combined disadvantages associated with using copper-based greases on braking systems, probably outweigh any advantages. For the mechanic, the easiest way to go is to switch over to a copper-free alternative for all brake work.

The advantages of using a ceramic-based grease, on the other hand, are numerous. An important advantage is that ceramic-based greases can withstand the high temperatures at work in the brakes. The high-temperature stability means that the pads can move freely, eliminating factors such as drag and minimising uneven wear.

Possibly the main benefit is that ceramic-based greases can be applied wherever sensitive electronic components are utilised because it does not contain metal particles and is therefore non-conductive. Ceramic-based greases are highly versatile because you can also use them to coat the threads of spark plugs, glow plugs or for other high-temperature applications.

Copper grease, the trusty old partner to the experienced mechanic can cause problems if used on the current crop of braking and driver assistance systems. Copper grease used to be the go-to product, but many are turning their back on it now because times and technologies have changed.

The technological advances of the last few decades mean that copper-based greases are no longer the universal, one-product-fits-all choice. Today, it’s easier for busy garage professionals who cannot afford the inconvenience and the reputational damage of customers returning vehicles with complaints to simply use a product that will work first time, every time.

Pro maintenance for the catalytic converter system

The catalytic converter and other system components, such as the oxygen sensor need cleaning periodically. Vehicles that spend most of their time being driven around cities are prime candidates for building up deposits in the catalytic converter. Despite fuels being cleaner than ever, particulates from combustion still build up in the catalytic converter.

Drivers often only notice that the exhaust aftertreatment has actually not been working as it should after long motorway journeys, where high speeds and high temperatures blast the catalytic converter and gasoline particle filter free of blockages.

Catalytic system component maintenance

BIZOL Pro Catalytic System Clean+ p82 is a professional-grade cleaner designed for use with the right tools in the workshop. Its formulation cleans and protects the catalytic converter system and gasoline particulate filter (GPF). It also cleans intake valves and the combustion chamber. A single treatment already dissolves most of the deposits, nevertheless, it is advisable to use the treatment regularly to keep performance at its best.

The need to clean and protect gasoline aftertreatment systems is more pronounced in regions where fuel quality cannot always be guaranteed but certainly not limited to those regions. If left unchecked a build-up of deposits causes a deterioration of performance. Loss of power, engine vibration, etc, often the warning signs are ignored. And that is the reason why cleaning away the deposits is essential. Regular maintenance of the exhaust aftertreatment system is far simpler than dealing with problems or failures due to a lack of care.

Problems caused by a build-up of deposits in the catalytic converter and GPF include:

  • low performance
  • increased fuel consumption
  • increased emissions
  • poor driveability
  • poor starting & idle behaviour
  • emissions test failure
  • check engine (MIL) light illuminates

BIZOL Catalytic System Clean+ p82 frees particulate filters of deposits. And with the deposits gone, the aftertreatment system can do its job efficiently again, removing harmful combustion products from the exhaust gases as originally intended.

BIZOL Catalytic System Clean+ p82 is compatible with all proprietary engine oils and provide the following benefits:

  • restores performance
  • frees the particulate filter from soot and other deposits
  • restores gas flow and prevents premature filter failure
  • improves and restores the function of critical aftertreatment components
  • helps to prevent check engine (MIL) light illuminating due to blocked particulate filter

Anyone who has tried to get encrusted underseal off car parts will know how tedious and time consuming it can be. Wouldn’t it be great if you could cut that particularly annoying corner and save yourself the arm-aching work and the self-mutilation involved in removing bitumen-based underseal?

If you use rotating wire brushes or abrasives to remove underseal they get clogged up before you get a decent amount off and will damage the material underneath. A heat gun can speed up removal considerably, but heating up bitumen-based products releases fumes and can be messy and risky if you get the parts or bitumen too hot! Some people even resort to using petrol as a solvent, but do you really want to be soaking parts in petrol?

Well, there is a trick that can be used to significantly reduce the amount of effort required to get the result you are looking for. The solution, in both senses of the word, is BIZOL Gasoline Intake Clean+ c36. In the pharmaceutical world it’s what they call ‘off-label use’, put simply, you use a product for something other than is stated on the label; in this case removing bitumen-based underseal.

If you are familiar with the cleaning power of BIZOL Gasoline Intake Clean+ c36 in its ‘on-label’ function, then it shouldn’t really come as a surprise to you. Nonetheless, you will probably still be pleasantly surprised by just how effective it is at softening and shifting bitumen underseal and the speed at which you can work.

But how can I use Gasoline Intake Clean+ to remove underseal? Well, first you need to don a pair of gloves and a pair of goggles, remember safety first! Once you are ready to start work, just spray the parts that are coated in underseal with Gasoline Intake Clean and watch as the underseal softens before your very eyes.

The trick here is to treat a relatively small area because you need to remove the underseal before the solvent evaporates. If you spray too large an area, the solvent will evaporate before you have a chance to remove the underseal.

Now, when you scrape, large amounts come off at once or if the parts only have a relatively thin coating, you can just get a cloth or paper towel and rub the underseal off; it is like magic!

Imagine, not having to put off cleaning parts or parts of a vehicle underbody any more for fear of blisters, getting covered in dirt or scraping your knuckles trying to remove old underseal. Happy days!

If you want to remove underseal from hard-to-reach areas when performing repairs or restoration work, the extension hose really comes into its own, as you can get at areas that are simply inaccessible to heat guns or drills with rotating brushes.

The other way of removing underseal without damaging what is underneath, is ice blasting. Ice blasting, however, requires specialist equipment and only companies with the correct tools can do it, meaning that it is very expensive. Why not try a cheap and straightforward alternative instead?

Exhaust aftertreatment system maintenance

All filters need to be cleaned or replaced at some point. In the case of gasoline particulate filters (GPF), for instance, particulates from the combustion process build up over time, despite fuels being cleaner than ever before.

In the case of diesel particulate filters (DPF), most of the difficulties experienced by the drivers of diesel vehicles are due to the way the aftertreatment system is intended to function. Short journeys and urban traffic are bad news for diesel particulate filters. The slow pace of traffic in congested cities mean that diesel exhaust gases rarely get hot enough to initiate the purging procedure.

The engine control unit will only start the purging process at exhaust gas temperatures above 650°C and herein lies the problem. If the parameters set in the engine control unit prevent the initiation of the purging process, then the procedure must be initiated manually, either by connecting the vehicle to a diagnostic computer or by means of a fuel additive.

If the partially blocked diesel particulate filter is not purged, any further accumulation of particulates will restrict the flow of exhaust gases, eventually forcing the driver to act. Failure to ensure the filter is purged leads to reduced performance, increased fuel consumption and, finally, DPF filter failure.

Ultimately, what this means for drivers of diesel-powered vehicles is that they have two choices to ensure that the filter is kept clean without a visit to the workshop. The first option is to take the vehicle on regular trips out of town, wasting time and fuel in the process.

The second option is by far the simplest and involves just pouring a tin of BIZOL DPF Regeneration + d61 into the fuel tank. Using an additive is the most convenient method of keeping the DPF free of soot and other contamination. There is no need to change driving habits and all that is needed is a tin of additive every third tankful of fuel.

Catalytic system component protection

BIZOL Catalytic System Protect+ g82 is designed to clean and protect the catalytic system including gasoline particulate filters (GPF). One application already dissolves many of the deposits, but it is advisable to use the treatment regularly to keep trouble at bay.

The need to clean and protect gasoline aftertreatment systems is more acute in regions where fuel quality cannot always be guaranteed but is actually necessary in all territories. If left unchecked a build-up of deposits will initially cause a gradual loss of power etc. Many telltale signs are ignored and put down to general wear and tear, which is the exactly why cleaning away the deposits is essential because it is far better (and cheaper) to prevent damage, than to cure it.

Problems caused by a build-up of deposits in the GPF and DPF include:

  • low performance
  • higher fuel consumption
  • increased emissions
  • poor driveability
  • poor starting & idle behaviour
  • emissions test failure
  • check engine (MIL) light illuminates

BIZOL aftertreatment system cleaners free particulate filters of deposits. And with the deposits gone, the aftertreatment system can do its job efficiently again, cleaning the exhaust gases as originally intended.

BIZOL Aftertreatment System Cleaners

BIZOL Catalytic System Protect+ g82 and BIZOL DPF Regeneration + d61 are compatible with all commercially-available fuels and provide the following benefits:

  • restores performance
  • frees catalytic converters and particulate filters from ash, soot and other deposits
  • restores gas flow and prevents premature failure
  • improves and restores the function of critical aftertreatment components
  • prevents check engine (MIL) light illuminating due to blockages

The current energy crisis is forcing people to find ways to reduce all forms of energy consumption, from turning down the heating at home, to making only essential journeys in their vehicles. If you rely on your own vehicle to get around, there are a number of ways to minimise fuel consumption. While some methods may seem obvious, it is surprising how often even simple methods are ignored when the price of energy is not concentrating everyone’s minds.

We have drawn up a list of tips on how to get the most from each tank of fuel

Remove accessories, such as roof racks when not needed

As handy as roof racks, bike racks or roof boxes are, unfortunately they act as a brake and the higher the speed, the greater the wind-resistance. Anything that reduces aerodynamic efficiency, increases fuel consumption. The extra drag saps power and the only way to compensate for the lost power is to open the throttle wider. So, as soon as you no longer need a roof box, roof rack or bike rack on the vehicle, remove it.

Keep the vehicle well maintained

Ensuring that the vehicle is in a good state of repair sounds obvious to most people and is what the vehicle manufacturer advises but, sadly, is often neglected. Keeping a vehicle regularly serviced and properly maintained can have a significant effect on performance, overall running and fuel consumption. Even something as simple as getting the air filter changed at the specified service interval can make a substantial difference to both fuel consumption and engine wear.

Check and correct the tyre pressures

Underinflated tyres affect road safety and increase both braking distances and fuel consumption. Underinflation places excessive strain on the tyre sidewalls and carcass, ultimately leading to premature failure. More immediately, however, underinflation equates to greater roll resistance, which demands more power from the engine. Typically, fuel consumption increases by around 3% per 10% underinflation of the tyres, i.e., there is a 6% increase in fuel consumption if the tyres are underinflated by 20%.

Slow down

Driving around at low speed is not the answer, but even a slight reduction in the road speed can have a considerable effect. Speeding up to overtake another vehicle is usually not worth the cost of the extra fuel. Especially in city traffic, you often notice the vehicle that you have just overtaken is right behind you at the next set of traffic lights. So, when appropriate, apply just a little less throttle, especially on flat or downhill stretches of road, when a minimal throttle opening can maintain speed and massively improve economy.

Select the highest gear possible

Change up to the highest gear possible, as soon as possible. Care should be taken, however, as changing up too soon can place the engine under excessive load, actually resulting in higher fuel consumption. Nowadays, cars often have a gearshift indicator, informing the driver the optimum point at which to change gear. The indicator simply flags up when the engine is in the right speed range.

If your vehicle does not have a gearshift indicator, all you need to do is check the rev counter and change gear when it is appropriate to do so. An engine speed of 2,500-3,000 rpm is usually sufficient so that an upshift does not result in the engine speed dropping below 1,500 rpm.

Another technique that can be used is block gear changing, i.e., changing gear from 3rd to 5th or 2nd to 4th or 4th to 6th. Block changing prevents wasteful engine idling between gear changes; when the engine is decoupled from the gearbox. Note, when block changing, you must ensure that engine speed does not drop too low due to shifting two ratios at once.

Keep less fuel in the tank

Ironically, keeping the tank filled up has a negative effect on fuel economy. Diesel, for instance, is heavy. The more fuel the vehicle has to carry around in the tank, the greater the weight penalty. For example, a tank containing 70 litres of diesel, weighs approximately 57 kg, which, if only half full, saves the lion’s share of 30 kilos.

Adopt an anticipatory driving style

Using defensive driving techniques can bring numerous benefits, such as increased safety and improved fuel economy. Adopting such techniques is quite simple, the most important principle is to observe your fellow road users, i.e., keep an eye on where vehicles around you are and try to predict what manoeuvres they are about to perform. If you notice another vehicle is about to move into the space between your vehicle and the one ahead, you can ease off the accelerator, thereby significantly reducing the likelihood that you will need to apply the brakes but still maintain momentum.

Brake less frequently and severely

Applying the brakes always wastes fuel, because fuel has been burnt to get vehicle moving in the first place. When you apply the brakes, kinetic energy is converted into heat; the heat generated in the brakes is wasted to the air. Braking, of course, also increases overall wear, so the less you brake, the less wear the vehicle is subject to as a whole. Coast up to a junction and change down through the gears during the approach – rather than driving right up to the junction and applying the brakes hard; a style more commonly used by motorcyclists.

Avoid using the air-conditioning system

Some air-conditioning systems are more efficient than others but all air-conditioning systems consume significant amounts of power. The energy required to pump refrigerant around the system directly affects fuel economy as the compressor is driven by the engine. Use the air-conditioning system sparingly if you want to make fuel savings, as some systems can cause as much as a 10% increase in fuel consumption.

In hot weather, and if the prevailing weather conditions permit, you can open the vehicle windows at low speeds instead of using the air-conditioning. However, the higher the road speed, the higher the wind resistance. As the road speed increases, eventually it gets to a point where keeping the windows closed and using the air-conditioning system actually saves fuel!

Cut out unnecessarily idling

Idling in traffic or at the traffic lights costs fuel and is the reason why manufacturers introduced automatic stop-start systems. Emissions, and thus fuel consumption, can be reduced by simply switching off the engine. Do be careful though, as you need to weigh up the benefits of turning off the engine beforehand. Switching off for 30 seconds at the traffic lights is barely worth it unless the vehicle is equipped with an automatic start-stop system, but if you are stuck in a traffic jam it makes perfect sense. What drivers must remember is that there is no steering assistance or brake assistance when the engine is switched off, so think carefully before turning the engine off.

Remove excess weight from the vehicle

Carrying excess weight around affects fuel economy, after all, low-cost airlines have been making customers pay for increased payload for a long time now, i.e., passengers have to pay for hold luggage. If you can afford to leave baggage at home, many people do.

Simply taking items out of the vehicle that are not needed will increase the distance you can travel before needing to refuel. You will, however, only achieve noticeable gains if you remove heavy items from the vehicle, taking smaller, lighter items out achieves negligible results. Do not expect massive savings because, whilst it can make a contribution to fuel economy, it is not a gamechanger.

A pool of fluid forming under the vehicle caused by a leaking coolant component is not a welcome sight. When the cooling system springs a leak, it can quickly become a danger to the engine, but if treated quickly need not cost a fortune to remedy.

Plug the leak

The main thing to do if the cooling system is leaking, is to find the source. Has a hose come loose or is there a hole in the radiator? In most cases a simple low-cost solution will suffice. The coolant system repair additive BIZOL Radiator Repair+ r71, offers a quick and reliable solution to cooling system leaks and is suitable for use in all vehicle cooling and heating systems.

It is simplicity itself, because the additive seeks out leaks, wherever they are, not just in the radiator but the entire cooling system and then seals them safely. The use of special polymers mean that leaks are sealed effectively without any risk of clogging.

Better safe than sorry

Figure 1 – Sign of a radiator leak

At the first signs of seeping or minor leaks, add a can of BIZOL Radiator Repair+ r71. We all know that prevention is better than cure, which is why it makes perfect sense to act before it’s too late and the car breaks down at the roadside. If you have to add water regularly or drops of coolant keep appearing under the vehicle then there is a problem which needs addressing.

Leaks from the heater matrix can also be a major headache, as often the entire dashboard need to be removed to effect a repair. Removing and refitting the dashboard to replace the heater matrix is usually a complex job and something to be avoided unless entirely necessary.

And that is where BIZOL Radiator Repair+ r71 can also help, as it can cure minor heater matrix leaks without all that work, saving a lot of time money and effort in the process.

How does it work?

First, check that there is not a big hole in a cooling system component, our product is good but cannot plug major cracks, holes or do anything about a disconnected hose. The normal procedure is to make sure that there is enough coolant in the system and then just pour the contents of the tin into the radiator or expansion tank.

Safety first!

Figure 2 – BIZOL Radiator Repair+ r71

Before attempting any work on the cooling system, you must wait for the system to cool down fully. If the cooling system has boiled over, wait at least 15 minutes for the steam to clear and the system to cool down.

The cooling system is a pressurised system, which is why you must never remove the pressure cap before the system has cooled down, regardless of whether there is a leak or not. If you remove the pressure cap when the system is hot, the coolant can spray out and scald you!

Fill the cooling system to just below the maximum mark and pour in the contents of the tin.

Start the engine and let BIZOL Radiator Repair+ r71 do the hard work. Replace the pressure cap, start the engine and allow it to idle for 10-15 minutes, then switch off and let the cooling system cool down. Check the coolant level when the engine is cold, make sure there is enough coolant in the system and adjust as necessary.

Fixing radiator leaks could not be easier than with BIZOL Radiator Repair+ r71.
