I use 93 always because compared to 87 and 89 it drives noticeably better and has better fuel economy. First started using premium fuel with the Camaro and never turned back.
Around me, North Western Indiana, certain gas stations have 91 and the others have 93. Marathon, Luke, and Family Express has 91 where Speedway and Pilot have 93. Maybe try a different station? Really tho it's a negligible figure.I think all we have around here in iowa is octanes 87, 89, and 91. Havent came across any 93 yet
Filled up in Gary Indiana 3 days ago for 3.98/gal. Premium. Lowest they have been in awhile.Im afraid to ask what anyone else is paying for gas lol. Probably better than me
Midgrade should be more than fine for that. The heat isn't too bad yet for this area to bump it up to premium. I don't ever recommend regular. Always midgrade at least. Just beware of Illinois drivers. They think the left lane on the highway is for going just the posted speed limit and that's it. Regional tractor drivers from this area feel like lane signalling is not needed as well. Oh, and fill up before crossing the into Illinios. The gas instantly gets higher right over the border.Question for those of you living in the flat parts of the US. For driving across Kansas, Illinois, and Indiana on I-70 in an ECO MT, what octane would you recommend? Basically I'm going to be sitting on Cruze control for hours on end. Central Missouri is hilly enough that I'll run 91 or higher depending on what's available. Northeast of Columbus, Ohio I'll run 91 or higher to handle the hills of the Appalachian mountains.
