I have a few stupid questions for you guys! Lurked the forum a bit, but still have some stupid questions.
Bought a 2018 Cruze, and found in the manual that apparently I should only use 87 and higher, with no more than 15% ethanol. I have no idea what the dealer filled me up with, but I put in 89 for the **** of it. Gas mileage is minimally better, but the car feels much more peppy and smooth. It's not as sluggish or jerky as it was previously during acceleration.
Here's the question everyone seems to debate, is there any reason to use 91, or look for lower ethanol levels? Would a higher rating actually increase efficiency or performence more so?
Second question, I currently live in a high altitude city. Once I move to sea level in the next few months, would it be beneficial to use a different octane level? Apparently air pressure is a factor in all this.
Sorry for the stupid questions, never owned a decent vehicle or something with a turbo, so all the debates on the subject can be confusing for an idiot like myself ? With my previous rust buckets I just tossed in good ole 85, but that's apparently a bad idea with this vehicle.
