Had a question for california drivers. I got my honda hatch sport with the TSP stage 1 Ktuner flash and have been just running 91 premium since that's the highest octane we got, but have been tempted to mix a couple gallons of e85 or 100 unleaded with the 91 to make a 93 octane. I don't have an e85 fuel flex kit but have read I don't need one to blend so long as I only use a couple gallons. Just wanted to see if anyone has done this and see if its worth exploring. Any advice would be nice.
