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.Has anybody ran VP C-12 fuel, if so how does it compare to C-16 in performance.
We use a meter that measures specific gravity against a test solution $30.00 a quart, meter is about $250.00 I think.Bill -- what do you use to test fuel and is the equipment expensive?
According to VP Racing fuel site the C-12 & C-16 are both leaded fuels.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
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 ????
