Fuel check question

Thanks for the reply Travis.

Would you mind telling us what some of the more stable fuels are?

P.S. for 69Cobra....Fuel cannot be scooped out of the tank. Fuel must be drawn from a fuel line that is part of the fuel system. The best way is to use a fuel valve designed for drawing fuel.

Where would I find one of these fuel valves?

Travis, since paying attention to where my fuel tests I've never seen it in the upper half of the spectrum. For the most part it will usually be slightly below the halfway point.

I am at a loss to why one half of the "window" is totally eliminated. With fuel going lower on the scale with exposure to air the lower part of the scale could be a bit wider. Maybe right on or perfect could be 3/4 of the way up the window instead of halfway?

Travis, thanks for that post only got warned once about my fuel, so I brought my jug to have tested. Kinda felt a bit stupid doing it that way but the official never said a word, checked my gas and gave me the thumbs up. I've met several racers who had issues race after race they only cured their issues up by switching fuels. Your results may vary. Joe

Jody, I think this might be a div 7 thing. The year before last at Sonoma, the div 7 guy told me my fuel (C11) was "marginal" and he would let it go but don't come back with it next round. I took the jug down to fuel check and one of the div 6 guys was there and checked it, said it was ok. Just to be safe, I bought 5 gallons of fresh and used it the rest of the weekend.
Ran the rest of the season with what was left in the barrel, all div 6 races, and nobody complained.

Couple of years ago, I had some C12 in my fuel cell from the Fall Vegas race.

I brought the car home and left it on my open trailer, covered up, all Winter .
When I went to Firebird in March, I siphoned the old stuff out , wiped out the cell and put 5 gal. of fresh C12 in it.

After T.T. 's , I took the old stuff over to fuel check... Whatta ya know? ...It checked right in the middle..Exactly the same as the new stuff.

Needless to say, I added and burned up the old stuff all weekend.
FWIW, I never had a problem with C12 bought at NHRA races.

I never failed Fuel Check. I always bought my fuel at the track the day of the race. Whatever was sold at the track was what I used that weekend.

It does seem odd. Fuel passing at Woodburn the week or two before then marginal or failing in a different Division with a different meter.
