I didn't realize that 91 octane doesn't contain ethanol! I know that regular unleaded here has 10% ethanol so I'm assuming 88 octane has it too. Who buys that E85 I'd like to know? In answer to Frank's question, the engine sounds fine.

Thank you. I will use up this full tank and try 91 next time to test it.
