Yeah but it sounded like he was saying Trevor's was the same, and he was running e85. Did I interpret wrong?

Yes because we haven't seen inside Trevor's cylinders yet. Regardless he has an exhaust valve leaking and so far no one has had a burnt or bent valve so that really only leaves us with the carbon buildup option.

BP mostly unless I don't feel like driving to one and won't be beating on the car then it's whatever 92 octane is nearby.
