Re: VP Reformulating C11, C23 and C25
 

We had several 5 gallon containers of C12 bought in 2008, originally filled from a barrel but full and stored in a shed. Last spring we finally got the car back together, poured in the old fuel and set the record first pass, fuel tested fine,
A few weeks ago still using up rest of the old fuel ran great numbers on the dyno...just my experience yours may be different.....

The octane was raised about 7/10s of a point in c11 c23 somewere from 7to 9 and the c25 was raised about a full point. The pro stock motors were having a problem with detination so the change to c 25. C11 was always for a little lower compresion motors and when ran in higher compresion motors it to had its problems. It maybe just to bring things more in line with todays motors higher rpms. I think the prices will be about the same but if car gas goes to 5 dollars race gas will follow. Tom

I had trouble many years ago with C-12 not passing. Since I started running the Volare I have been using C-11 with no problems. Found out the hard way you can't store any race gas in anything but metal cans. The plastic gas cans are ok for the weekend but you must return race fuel in a metal container after the race. It will last a long time stored properly. That includes fuel cells. Jim

Is there any reluctance at the fuel check by NHRA to pass non VP fuels ??? I used Rocket for a while and it seemed they wanted to moan and groan a little or was it my imagination ???
