My car likes to be a couple percent richer on C11. I have found nothing else as fast in my car as C11. Slightly faster with no tuning changes. Everything else likes 13.1-1 to 13.2-1 like that Sunoco crap that won't always pass fuel check, likes 12.8-1 to 12.9-1 with C11. Always passes fuel check as well. Faster and checks legal. Have to haul it in the trailer. Not safe.
