So, actually, I would expect running 10% ethanol gasoline to maybe cause problems.

It is the only thing that makes since. I have filled up with 93 octane and those I have had trouble with are ethanol blends of 10-15 percent per volume. The higher octane fuels without ethanol such as shell's v power I have not had any trouble and if you could find some Amoco 103 fuels I am sure it would do even better. Factory tuned SR20DETs where meant to run on 98+ Fuels.
