That makes it easy, I would think. 95% of the stations around me are all 92. I didn't want to get the full-on 93 tune because of it. I don't think filling up with gas over your octane tune will hurt anything.
This is true. I have the Roush tune which calls for 91 octane, but I have to use 93 because that seems to be all there is in premium grade around here. It's just a little wasted money per gallon for those extra 2 octane points, but there are no ill effects or problems associated with using 93 over 91.
It says 91 because they have to use the lowest acceptable grade for states with shit gas like CA. You pay more for 91 in CA than you do for 93 on the right coast. gasbuddy app will give the lowest prices in your area for premium.
I've got GasBuddy on my phone. They don't specify the octane, though. Would make life a little easier if I could filter that out.
