I have never seen a performance difference useing 110 verses C16.for the past 3 years 110 is what I have used for all racing except NCS events which we are required which to me makes no sense the way the prices are I have never had vapor lock problems with 110 and there is NO performance advantage with the higher octane on the C-12 you would not see a change eather.the actual usable compression of these motors is what keeps you from seeing any performance ganes beyond what they can produce past the 110/111 octane mark

I agree, i can see no performance difference, we have been using Rocket 111 which is the old Unocal 76 brand seems to work very well. The C-12 would be for the NCS Race in April, C-16 price has gotten out of hand.

I have had my best performance with the Rocket 111 its my favorite to use but its hard to find around here unless you order it I had access to it because of a guy I use to work with bought it in 55 gallon drums for his race car

You guys may be on to something. Ever try to writing it down and send it in as a rule change? Sounds reasonable to me.

Your right jim but there are lots of people that think its better because of the "additives" in the C-16 or think there getting a performance gain from it just because it is 116 octane. it is a way to cut costs for host tracks and racers to run a fuel that gives them what they need without wasting there money. unless QSAC is getting endorsement money from VP which I know there not I don't know why they promote it or use it. but the bottom line is people like buying that overpriced over octane fuel I have heard it all to like that's all my car will run on or the other stuff will vapor lock. it could be submitted but I don't think it would get approved just my opinion

Copied from QSAC Rule book:

"TRACK FUEL (11.22.07) All competitors will be required to use a pre-mixed, host-track pro-vided fuel. The fuel specified is VP (brand) C-16 or C-12, mixed with 2 ounces of AmsOil Saber 2-stroke oil per gallon. QSAC recommends that the host track buy fuel in 5 gallon containers. This will allow unused fuel to be sold in 5 gallon increments to participants after the racing event is completed."

You can run the C12 at the NCS

This is the question asked....."Has anybody ran VP C-12 fuel, if so how does it compare to C-16 in performance."

"I" found NO performance gain from C-16.

Btw - thanks dpopham. :thumbsup:

I was reply to the statements about a rule change. It's not necessary as the option already exist. I believe we ran c12 at an NCS in Easley in '08. But I'm not a good judge of performance gain/loss. I just try to go around in circles without running into anything:thumbsup:

VP C-12 is unleaded C-16 is leaded . C-12 burns very clean a good thing, C-16 with the lead in it has much better lubricating qualities.
In our Qsac West point series we test fuel for additives, any fuel found with methyl alcohol/methanol is not allowed.
Even some pump fuel can contain methanol opening the door to add more, so we don't allow any fuel that contains any additive, I know not many clubs have test equipment so its simpler to just mandate C-12 or C-16

Over the last three years I tested many of our racers fuels in a blind test and found a few with methyl alcohol/methanol, Union 76 , and others can on a regional bases can contain these additive.There are some additives out there that are carcinogen's benzine etc. I think that's why Qsac mandates a C-12 or C-16 and other unoxygenated racing fuels.
Thanks Bill Scott

Bill -- what do you use to test fuel and is the equipment expensive?
We use a meter that measures specific gravity against a test solution $30.00 a quart, meter is about $250.00 I think.

we also have chemicals that test for additive about $65.00 2-3 year supply
you have to be a racing entity like Nascar or Qsac to buy them.

There is a simple test for methyl alcohol/methanol called 30/30/30 test, you use equal parts methanol , water , fuel sample, in a beaker this will reveal any water soluble additives including methanol.

If you do seach on racing fuel testing there is tons of info out there, or give me a call.

According to VP Racing fuel site the C-12 & C-16 are both leaded fuels.

You are 100% correct, I should have said lower lead and lower octane. Last time I purchased it, I think it was very close too the same price as C-16 ????
C-10 is unleaded and also worked very will !! . I still like C-16, better Lubricating
Fuel cost per race is minimal compared to some of the other costs, but any place you can save is a good thing !!!

The fuel rules are pretty open to what can be run. Past NCS races have run C-12, Sunoco Racing and CAM II due to availablity/cost issues. As in the past, I think it would be prudent for the host tracks to get QSAC's approval to run any variation from C-16.
