Too much misinformation going on. Too dry, made for high altitude... garbage. 100LL is rates 100 octane lean, 130 octane rich, compares roughly to a 110 race fuel. I have a 461" SB2.2 engine in my dragster at 15.5 to 1, I buy 55 gallons at a time and either use Turbo 108 Plus or Race gas concentrate, a bottle to 55 gallons, My best time with Q16 is 4.71 in the 1/8, with aviation fuel 4.74. $85 for 5 gallons of Q16, under $20 for aviation fuel. I don't suggest it for street use as it is illegal. E85 is a good choice for street if available.

Back in the day, we could pull right up to the pumps and buy whatever we wanted, not anymore!
I've been to every airport in a 50 mile radius, and not one will sell to you unless you pull your plane up to the pump. Sure would like to know where you can buy it by the 55 gallon drum.
