I agree Charlie, my 85 Mustang Stocker runs a couple hundreds quicker on Chevron 89 midgrade than VP C12.And putting C12 in my 8.4-1 compression 302 is like feeding my dog steak and lobster.

Rory, have you tried C11 in the Mustang? I found it is worth a few hundreds over C12 in my low compression combo. I going to try C9 next, supposed to cost less and possibly quicker according to VP.

I wasn't talking about pump gas, I was talking about the major fuel suppliers providing a lower octane fuel that can be checked by the NHRA.
The lower cost would be welcomed by a lot of us.

Jim, I did try some C11 several years ago, didn`t pick up any, but all I did was pour it in the tank. Maybe with tuning there may be something, but personally, I`d like it if a lower cost approved fuel was available too. About 10 years ago, when I first started running the Mustang, I tried VP Motorsport 110 or Red, I can`t remember the exact name. It was on NHRAs list of accepted fuel, but it would never pass fuel check, even from a newly opened drum. Another racer at the same meet had his same blend of VP fail as well.

Sunoco 110 (Purple) is by far cheaper than similar VP fuels. It is on the approved list.

I know the brand Rocket Fuel was lots cheaper than VP and Sonoco a few years back. Not sure if they are around anymore

We have used both the Sunoco and VP fuels. VP may be marginally better but not significant enough to justfy the higher cost of VP.

Either fuel at a 105 octane rating is overkill for our 9:1 motor. It would be nice if the NHRA would allow VP, Sunoco, Rocket, et al to provide a fuel that is 100 octane and 95 octane that is easily checked by the NHRA.
All I am looking for is to use a fuel that will help our car run better.

Does anyone know what the fuel inspector is looking for at fuel check? Specific Gravity? Purity of the Fuel? Other elements?

C9 is 92 MON, C10 is 96. Any reason those won't work for you?

This past weekend I paid 42.50 for 5 gallons of Sunoco purple and 67.00 for 5 gallons of VP C11. Total ripoff.

I remember the old man Heffler pushing rocket fuel at me a couple of years ago. Said he got the same performance as when he ran VP C11. Figure I will find some and give it a go. Just got to find someone who sells it in the Dallas area
