Beard.....03- .05 in the 1/8, just swithing fuels? That would be about .10 in the quarter!!! What else did you do? Change tires, take weight out and ice the intake??? Or did you spin on the first run and hook on the second??

There are too many variables, I think, to just say a fuel picks you up over another fuel. For example, did you cool all of your fluids down to where they were on the first run? I know my car picks up a little on the second run, just from the oil, trans fluid and rear end being warmed up. Did you run the same lane? Did you leave the line exactly the same? Did you shift at exactly the same rpm?

I was comparing et's from my log books from when I used VP, Sunoco Blue, and now Sunoco Purple........and I've found I'm running faster now then ever. So take it for what it's worth!!
