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
