    Rec 87 or Rec 90 is 100% gasoline, both will do better than 93 gas, especially in the turbo edish

    The owners manual says to use top tier detergent gas. I feel that all turbo and supercharged engines should run 91+ octane because boost requires a tighter gap spark plug. Nobody wants LSPI ever and especially on a boosted engine! If you trade in your car every 3 years then it don’t matter but if you don’t want holes on pistons and other things related to octane then run the highest possible.

    +1 on this I run 89. My son likes(or at least notices the performance difference) 93 in #3(2014 LT) I have been good with 89 with mine #4 + #5 2013 and 2015 LTs. 93 has never been all that much better for my taste or I don't use more than 1 tank. So 89 octane is my vote.

    I live 5 minutes away from a Costco (Top Tier gasoline) which sells 93 octane for the same price that most other stations sell their mid-grade 89 octane, so I run the 93 there. Since it's warm/hot 9 months out of the year, I find I get a little better mileage from the higher octane as well as running smoother. Now if I could just get out of doing short errand drives everywhere.

    I’m glad I joined these forums and been reading about using higher octane. I have a 2018 Cruze LT automatic. Got it in November. It always seemed a bit sluggish to me and would hesitate at times. Me knowing nothing I always used 87 octane since that what it calls for in the user manual. So I decided to give 93 a try since the gas station I use carries it. I can honestly say, what a difference! Car is no longer sluggish and doesn’t hesitate anymore. Wish I had found these forums when I first got the car. My car is very happy now.

    So this was my first 500mile tank, and it happened after i had put in some 90/0E octane, a bit over 4 gallons into a half tank of gas.... and then at just under a 1/4 tank of gas I filled up with some 93octane...

    There's a Sunoco across the street from my work so I've run 93 in it since I got it. I think I might have put 91 in a few times when I have been traveling but it's pretty cheap insurance is the way I see it.

    Also I don't know if this is the case everywhere but at my Sunoco, the 93 is usually the same price or possibly a couple cents more per gallon than the 91 so why not?
