Gasoline, Diesel, Oil and Radiator Additives
Types of Aftermarket Additives
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.
• 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.
Gasoline Fuel Additive
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:
• 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.
• 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.
