Diesel -(type 2) Used mainly in trucks and other heavy duty equipment, but now being used in cars and trucks. Has a higher BTU rating and can produce more power per unit. Currently there is more technology for clean burning diesel then gas and it does give better mpg. Most people don’t like diesel because of the louder engine and smell, but technology is allowing for quieter cleaner diesel engines.

Bio-Diesel – Simply made from soybeans or other natural source. Has been proven to burn cleaner. People can actually create diesel from fryer grease found at most restaurants. The process involves using lye to break down the fats and separating the fuel from it. I have seen these kits go for $2-3k, but it allows the user to produce fuel for as low as 70 cents a gallon. Bio-Diesel can be used in Diesel engines.

E-85 – Ethanol – In a nut shell, gas made from corn. Has been proven though not to give the fuel mileage of regular fuel.

Nitromethane – Used in drag cars, etc.

Propane – Alot of cars can be converted to propane driven, but there is not a great cost savings.

Kerosene – Used in most jet engines(not absolutely for sure, know an engineer that works for Boeing), not for sure about cars.

Hydrogen Cell cars – converts Hydrogen in water + electrical energy. Supposed to be the fuel of the future, but currently requires a lot of energy to produce the hydrogen from electrolysis(running a current through water and producing hydrogen gas)
