V.P. C-11 vs. C-12
We've got a 1992 Camaro J/SA car, 350 TPI. We run C-11 now, and
are happy with it. All I can get for this weekend is C-12. What should we expect, and what should we watch for. Thanks, J.R. |

You may be able to lean out the carburetor and/or run a little more timing as detonation will be less of an issue...

Re: V.P. C-11 vs. C-12
I doubt that you will see any difference between the two fuels. I switched back and forth several times between 11 and 12 and did not see any real difference. I typically run C12 in my car.

Re: V.P. C-11 vs. C-12
Mine is just a tick quicker on C11, but mine has to be fattened some up to see it.
I doubt you will see much difference.

Re: V.P. C-11 vs. C-12
Guys, Thank You for the help. Mike & Ed, your answers this morning
were right in line with what V.P. told me this afternoon. We don't try to complicate things, but living in Canada can have its challenges. To get C-11 shipped to me for this weekend with freight was $50.00 a gallon. A local snowmobile racer and V.P. Dealer has fresh C-12 in stock for the "Rock Bottom" price of $25.00 a gallon. The joys of being Canadian. Thanks again everyone. J.R. |

Mike, I just printed NHRA's approved fuel list, looking for something else. I don't see that one listed. Lowest Renegade shown is "110+".

Re: V.P. C-11 vs. C-12
Renegade offers a lineup of race fuels for virtually every application, but they didn't submit all of their fuels to NHRA to be added to the accepted list. So for now, the Pro Crate 108 can only be used where the accepted fuels list doesn't apply. But Renegade may look at adding more of their fuels to the list.

Re: V.P. C-11 vs. C-12
NHRA may not want to add any more fuel blends to the list, but we'll see.
I'll give you some info on fuel specs. Sunoco 110 motor octane is 106 VP 110 motor octane is 107 VP C-12 motor octane is 108 The Renegade Pro 110 motor octane is over 108 |
