FUEL SYSTEM CLEANERS
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.

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.

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

The melodious purr of a motor, the velvety transition of cog-wheel, and the elegant voyage along the expansive highway — these are the unmistakable characteristics of a meticulously calibrated self-shifting gearbox system. But what transpires when the motorized ensemble falters, the cogs gnash, and the voyage veers into an unforeseen tempest? Get into the realm of automatic transmission problems, a domain where automotive aficionados and everyday motorists alike encounter the enigmatic intricacies of this complex system.
Driving is a blend of exhilaration and convenience, but sometimes, your trusty car can hit a snag. One of the most frustrating issues is a coolant leak.
Coolant, often referred to as the versatile 'antifreeze,' assumes the uncelebrated role of an automotive guardian, ensuring your engine's harmonious operation. This unassuming fluid stands as a bulwark against the scorching summer heat and the bone-chilling cold of winter. Nevertheless, when the vigilance of antifreeze wanes, and it embarks on an unauthorized journey beyond its confines, ominous troubles come into view.
