Running a steady diet of 93 should be no problem, IMO. Premium here and further west and north of Arizona is generally always 91 and it is hard to find a station with 93. It seems that East of here premium is 93.
BTW, my 1995 EVO runs great on 87 octane. For those that think your EVO needs high octane, it doesn't. The owners manual for my EVO says it needs 87 or higher octane fuel and that is what I use.
Interesting. Thanks. I'm just trying to figure out why my 07 EGU would now be showing signs of a lean tune after all these years. Just doesn't make sense. Don't want to through money at it if not necessary.
Unfortunately it's either 87 or 93 in this area.
