>> A better analogy might be airplane fuel and car fuel. Both are gasoline, but a different kind and not really repleacable Well, if we're gonna get technical.

AvGas (which is basically gasoline with a high octane) and JetA1 (which is basically paraffin.) I'm not sure JetA1 falls under the term 'gasoline' but obviously ymmv there. You can use AvGas in a car, it's the same stuff. AvGas has more kick (more octane) so its not necessarily great for the engine. I worked on an airfield a long time ago, and on occasion AvGas was used on cars (blended with normal gas it's not too bad.) Avgas is used on piston engined planes, JetA1 on jets and turbo-props. JetA1 is just good quality paraffin so can be used wherever paraffin is used.
