If you're running a class that requires fuel check it's best to get it at the track/race and keep it sealed up tight and out of sun light if it's in plastic jugs. If there is any doubt have the fuel check guy test it before you put it in the car. Another tip, if you run a car that requires fuel check DO NOT EVER put unleaded fuel in the tank as it will contaminate the entire system and your "good fuel" will not pass until you've completely flushed the fuel system several times with good fuel.

Just so you guys know, only a few years ago, there was an approved fuel that AV gas could be passed off as .Several of the more shall we say, budget conscience racers were using it. Someone upstairs must have caught wind of this, and it was removed from the approved list.

Was that VP-C9? I set the record one year and after making a run at the points race next year they said C9 is not in the book. Had to switch to C-10.
Questioned why and was told nobody used it?
