Not sure. I used 94 at Sunoco until they eliminated it due to it being environmentally unfriendly. For all those years, I saw no particular advantage of 94 octane in mileage or performance.
It has 110k miles now. Around 100k I got a "check engine" light. I think the MAF was replaced and the intake related items were cleaned (EGR, valves having to do with starting? Can't recall the list) It was something like $500. I noticed no change in performance after the maintenance.
