In Arizona we basically have 91 octane, but there are a few places that sell "racing fuel" which is 100 octane. My question is can you mix the two and at what ratio? Also once mixed, can you just reset the tables or would a tune be required? I would like to be able to boost the octane this way without buying octane booster. Anyone done this?
