91 Octane? What do you guys use? 87, 89, 93? That's what I have available to me in my area, it says on the cap (91 Octane). Gas is getting kind of expensive here in Maine, and I've been running Premium. I mean... 1.9L, 138HP normally aspirated engine seems like it would only need regular? I know its cleaner burning (Premium) but besides that...? |
