Well I have about 15 gallons of race fuel Sunoco 112 Octane I believe. It has been sitting in my garage for a year or two but I know for a fact that I put fuel stabilizer in before I left and not sure if anyone else did while I was gone. I asked them to but not 100% it was done, I am assuming it was taken care of.
If you want some of it, let me know. Located in Northern Colorado. Negotiate prices. I think I paid $6/gallon but won't charge that of course.
