I don't know which two classifications you are referring to, but the two most common are 100LL Avgas, and JET-A. The first is used in piston engines (like a car's) found in small prop planes ; 100 is the octane rating, and the LL means Low Lead. JET-A is used in turbine engines found on larger prop planes and on planes with turbojet engines; JET-A is similar to diesel fuel, it is just a higher quality for use in aviation.
Aviation fuel. There is aviation gasoline, Jet-A and Jet-A1 civil jet fuels, and the JP series of military jet fuels.
