Thats right, you are required to run a fuel that is on NHRA`s "accepted fuel list", and that fuel WILL be tested against the specs that NHRA is given, by the manufacturer, for the particular brand & version of fuel that you are claiming. Since "normal" gas station pump gases are not on the NHRA fuel list, there are no specs provided, so they are ineligible. "Lesser" fuel or not, if it`s not on the list, you can`t run it, at least at a NHRA divisional or national event. On my particular low compression, smogger Ford combo, I have tried Chevron mid grade pump gas at a local track test or bracket race, and it ran just fine, and actually a tic faster than the VP C12 I normally run, the problem lies in ensuring that all the pump gas has been flushed/drained out, so as not to contaminate the specs of the approved fuel when the time comes to ran a NHRA race.
