I'm sure many have been down the ethanol road before? Ethanol may assist the Sugar industry & give higher octane & yes, even cleaner fuel. Old school (non-ethanol) Higher Octane fuel is naturally cleaner yes due to additives but also due to less (bad) additives. A point few people even realise. This was my main point, sorry. I have found that even though 95 octane in a say, 9.4:1 engine is OK, with 98, it gets bit better economy whilst not needing fuel injector cleaner. I would NEVER suggest 91 octane. Have you not heard the Hyundai's & Daiwoo's beside you pinging there little hearts out? 91? Yes, I think so. Yes, even though they are twin cam?

Sensible rule -of-thumb: Multi-valve = higher Octane fuel = better
