List of gasoline additivesFrom Wikipedia, the free encyclopedia

Gasoline additives increase gasoline's octane rating or act as corrosion inhibitors or lubricants, thus

allowing the use of higher compression ratios for greater efficiency and power, however some carry heavy

environmental risks. Types of additives include metal deactivators, corrosion inhibitors, oxygenates and

antioxidants.

Fuel additives in general

Ether and other flammable hydrocarbons have been used extensively as starting fluid

for many difficult-to-start engines, especially diesel engines

Nitrous oxide, or simply nitrous, is an oxidizer used in auto racing

Nitromethane, or "nitro," is a high-performance racing fuel

Acetone is a vaporization additive, mainly used with methanol racing fuel to improve

vaporisation at start up

Butyl rubber (as polyisobutylene succinimide, detergent to prevent fouling of diesel fuel

injectors)

Picrate improves combustion, increases fuel mileage

Silicone is an anti-foaming agent for diesel fuel, but may damage oxygen sensors in

gasoline engines

Tetranitromethane can increase the cetane number of diesel fuel, improving its

combustion properties

Legislation

United States

The Clean Air Act was put into place in January 1995 in the United States as part of the efforts of the

Environmental Protection Agency. This act requires deposit control additives (DCAs) be added to all

gasolines. This type of additive is a detergent additive that acts as a cleansing agent in small passages in the

carburetor or fuel injectors. This in turn serves to ensure a consistent air and fuel mixture that will contribute

to better gas mileage.
