yeah I run av. fuel Its 100 octane and clean!! no additives in it!! it runs great an my quad and its alot cheaper than race fuel!! and I have a small airport 2mi from my house so why not run it! lol at 6.00 a gal. its way cheaper than race fuel at 8.50 a gal.? it makes the throttle response instant! and has a unique smell to it?
