E85 for more than 3 years now. Only use 93 when I can't find E85 traveling.


Keeps the tailpipes nice and clean and my wife says it smells like popcorn when I start the car.


One thing to keep in mind about E85...the non-ethanol part is standard gasoline, but the octane of the 'filler gas' varies widely from supplier to supplier.


I have seen 83 octane used and 93 octane used. RaceTrac uses 87 octane here in Florida. There are a few pumps around that use 93 octane as the filler. That's the gas I use when going to the Dyno.



Just something to keep in mind if you are chasing a magical 'octane number'.
