C-11 question
 

I have (2) 5 gal un opened pails of C11 in my trailer from Oct. .is it OK to use?

Re: C-11 question
 

You should be fine if it was stored correctly. Meaning, if the fuel was on a wooden floor or wood planks, and if the daytime inside trailer temps weren't far higher than the night temps, it should be usable. The Renegade crossover fuel, Pro Crate 108, has a shelf life of 2 years when stored correctly.
If you have any doubts, 2 new pails of fuel are far cheaper than a piston or two.

I felt pretty good till I read your last sentence. .so your saying if the fuel is bad it will go lean? It's been sitting in the trailer on a wooden floor all winter had one freeze but hasn't been past mid 80,s here in the DFW cluster F

Should be OK to run. As far as passing check might be another matter.

You should be fine. Take both cans over to fuel check if you're going to a sanctioned event and they can tell you if they are legal. I've never heard of C11 burning pistons before.

Hi Bruce, when you ran the small blocks was c11 faster than c12 and was there a difference in consistency for you? You can PM me if thats better.
Thanks

C11 is faster in low compression motors. Most low compression racers use C11 over C12. Jim

I am also interested

I like C11 for a lot of reasons. For me it has proven to be faster without suffering any reliability issues. I am the reason my cars have suffered reliability issues over the last 20 years or so. It all comes down to tweaking your combination. Obviously, you have to double check your metering/jetting and timing after every mechanical change you make. It's what makes the sport fun.

My thought is the light ends of gasoline that evaporate quicker (butane, etc.) have the higher octane ratings than the heavier molecules. Maybe the problem becomes detonation instead of going lean?
