Gasoline, Diesel, Oil and Radiator Additives

Types of Aftermarket Additives


Additives are at work in cars every day, protecting engines and enhancing performance. BIZOL develops products that contribute to the proven performance of BIZOL lubricants. All additives are exhaustively tested in the laboratory and in the field under real-world conditions.

Many additives solve specific problems and protect engines and fuel systems. These additives clean fuel injectors, bolster performance, prevent gasket leaks, keep engines and fuel tanks clean, and prevent engine damage from high mechanical loads.

Aftermarket additives are available that deal with specific problems and supplement protection offered by high quality lubricants. Aftermarket additives, while enhancing performance, cannot and does not increase engine horse power and performance beyond what the vehicle was originally capable of. They are, however, excellent products when used correctly and help restore performance in older engines.

BIZOL additives protect fuel systems, enhance lubricating oil performance, and protect cooling systems.

Gasoline Additives

Gasoline fuel additives have several functions. Firstly, there is the need to control the rate of combustion and to prevent premature fuel ignition. Secondly, there's the need to reduce noxious emissions, and, thirdly, to condition the fuel. These additives may be grouped as follows:

• Control of ignition characteristics: Gasoline engines use a spark produced by the sparkplug to ignite the fuel. This gives precise control of the ignition process and is one of the key factors controlling fuel economy and power. Gasoline ignites easily, and to ensure it does not ignite in the hot combustion chamber before the spark plug fires, antiknock additives are added that increase the auto-ignition temperature of gasoline. Octane boosters perform a similar function by preventing spontaneous ignition when fuel is compressed during the compression cycle of modern high compression engines. Uncontrolled gasoline ignition is particularly harmful to engines and must be avoided.


• Pollution control: One of the products of combustion is carbon monoxide, which is an odorless, poisonous gas that contributes toward the formation of smog. A group of products called oxygenates reduces the formation of carbon monoxide by encouraging more complete combustion. Gasoline may contain as much as 10 per cent oxygenates.


• Engine protection: A number of products are added to gasoline to prevent corrosion and formation of deposits. Antioxidants prevent the oxidation of gasoline, which results in corrosive and gummy deposits that block filters and injectors. Corrosion inhibitors reduce corrosion of metal components in the fuel system and combustion chamber caused by acidic compounds. Detergents are used to remove sooty deposits from fuel injectors, and lubricants provide lubrication of injectors and prevent deposition of gummy residues.

Gasoline Fuel Additive

Gasoline Fuel additives are divided into two groups, gasoline additives and Diesel Fuel Additives, and perform slightly different functions. The additives in gasoline serve primarily to improve the combustion process whereas in diesel they condition the fuel.

As in many other areas, additive technology is being driven by relentless development in automotive technology that seeks to extract more performance out of smaller engines while simultaneously reducing emissions. Gasoline additives have two primary purposes, engine cleaning and boosting octane rating:

Combustion chamber cleaner is an ash-free mixture of detergents and dispersants that cleans and removes deposits, thus preventing pre-ignition and possible dilution of the fuel-air mixture that results in poor running. It's ideal for oldecarsr engines and is compatible with all modern engines.

BIZOL Gasoline System Clean+ g80 cleans completely the gasoline system, including the injection system, valves and carburator. Restores initially lost motor power. Reduces fuel consumption and emissions through improved combustion. Protects against corrosion and oxidation.

BIZOL Octane Power+ g81 boosts fuel octane number (RON) and contains engine power molecules. Avoids mechanical damage caused through pinging. Recommended usage when the octane number is lower than required by the vehicle manufacturer.

Diesel Additives

 

Diesel fuel additives are used to clean fuel systems and to prevent fuel gelling during winter:

Diesel Additive cleans fuel injectors and improves the lubricity of ultra low sulfur diesel (ULS). It can be used continuously or, as and when required, to clean dirty fuel systems.

 
• Anti- gel: In cold climates, diesel is specially treated with anti-gelling additives. However summer diesel may not contain sufficient anti-gel and winterized diesel may not have enough anti-gel to prevent gelling during cold snaps. BIZOL Diesel-Antigel is effective down to minus 24 ºF (-31 ºC).

 Diesel engines use compression ignition instead of spark ignition. Fuel is injected into the engine cylinder at a precise time and is ignited spontaneously by the high pressures achieved during the compression cycle. Diesel fuel additives perform subtly different functions compared to gasoline additives. The additives have three main functions: to condition the fuel, prevent growth of undesirable bacteria, and to keep the fuel system clean.

• Fuel conditioning: There are several aspects to fuel conditioning. Firstly, the ignition characteristics of diesel are controlled by its cetane number, and cetane enhancers are added that improve cold starting performance. Secondly, in cold weather, waxy compounds present in diesel may crystallize, blocking fuel filters and causing fuel starvation. Pour point depressants are used to reduce the temperature at which these waxes solidify to permit cold starts in extreme winter weather. Thirdly, lower levels of sulfur in modern ultra-low-sulfur diesel have made it less conductive, and conductivity improvers are added to reduce the risk of static electricity igniting diesel during handling.


• Bacteria control: Although diesel contains no water, during transport and storage some water condenses in fuel tanks. Diesel is lighter than water and floats above it. This is conducive to the growth of bacteria, which contaminates the fuel and blocks filters and injectors. A biocide is added to reduce the risk of bacterial growth.


• Lubricity and cleanliness: The natural ability of diesel to act as a lubricant may not always be sufficient to protect high pressure injection pumps and fuel injectors, so, depending upon the fuel composition, lubricity additives may be required. During combustion, soot is produced especially when the engine is cold. This soot collects on fuel injectors causing partial or complete blockage of the injection nozzles. Detergents added to the fuel reduce this possibility and clean the injectors. Another issue affecting modern fuel recirculation systems is that diesel has a tendency to form resins and gums when heated. The recirculation of diesel fuel from hot injectors to the fuel tank may cause filter and injector blockages. Diesel stabilizers are added to reduce the likelihood of this occurring.


Oil Additives

 

BIZOL aftermarket oil additives are ideal for dealing with specific problems and enhancing engine protection between oil changes.

Radiator Additives

BIZOL manufactures additives for automotive cooling systems that are designed to keep cooling systems clean and to deal with small, hard-to-find leaks. These additives are compatible with modern cooling systems and help prevent serious engine problems by keeping cooling systems working properly.
