My track switched brands of fuel this year. They used to sell VP but changed to Torco. I was planning on using the VP C-16. Torco has a Mach 116 that has very similar specs to the VP. Specific gravity is the same and motor octane is 2 numbers less (115 vs 117). Does anyone have any experience with Torco fuels? Does the Torco fuels tune the same as VP stuff?
