Although there are alternative fuels that can work in gasoline engines, many cars are adapted to certain formulations of fuel and may not accept an alternative fuel. It is very important to check with your owner's manual to ensure your car accepts both gasoline and an alternative fuel before putting the alternative fuel in your car.
Liquefied petroleum gas, or autogas, can be used in cars from a number of manufacturers, including Ford, Toyota, Volvo, Volkswagen and Hyundai.
Regular gasoline that has been blended with ethanol, a type of alcohol, will work in a gasoline engine. Although there are some cars that will not run with ethanol, most cars accept up to 10 percent ethanol, and many blends of gas integrate some degree of ethanol for pollution reasons.
Regular gasoline that has been blended with methanol, another type of alcohol, will work in a gasoline engine. Some cars will not run with methanol, but most will run on blends with up to 10 percent.
Butanol is similar to methanol and ethanol as it is an alcohol, but because it is chemically closer to gasoline, it works in regular gasoline engines at higher concentrations than both methanol and ethanol.
Gasoline vehicles may be converted to diesel vehicles by changing the engine. At present time, however, aside from the above, there are not many options for alternative fuels in gasoline engines.
