I was close to choosing AVgas testing as a senior project for school this past week, simply because it's ALWAYS a debate when someone brings it up yet NO ONE has any REAL data other than here-say and conjecture.

Since I didn't choose it for my project, here's my here-say and conjecture . It's rated at 100 RON, i've NEVER seen any MON data, also i've HEARD the way the RON test is done is DIFFERENT than the one done for vehicles. I've HEARD it actually has better storage properties than race fuel, octane does not degrade nearly as fast since planes stay on tarmacs for extended amounts of time...

My car has gone 8.0's with it with the assistance of some methanol cooling, how much it contributed to octane is unknown.
