then why does a place like denver, have a different formulation of fuel.... Avgas 100 LL should be the same formula and chemical makeup no matter who makes it and where it is sold from I've bought 100LL in Denver to get home from a trip there, no noticeable difference in the smell, price or performance on take off and climbing other than having to lean it out a lot more to get have 50 F degree rich of peak at WOT before take off I was taught to always run the motor up to WOT and lean it out to peak EGT and then richen it up 25 to 50 F rich of peak at any airport above 3000 Ft. above sea level before take off, especially in the summer when the density altitude can get way above the local altitude

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.

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.
