does a 2023 gmc acadia 2.0 turbo engine use regular gas

91 octane has the same potential energy as 87 , There should be a label for the grade of gas to use . Try not to beat the hell out of it rockford , condition can be a problem down the road for a resale value . Any time you see a chalenger , firebird or camaro for sale it's safe to assume it's been raced . We used to call them disco cars .

Regular is not recommended according to be web site, so better use what is recommended by the manufacturer. I have heard of people damaging engines using low octane fuel in engines requiring high octane fuel, knocked a hole right through a piston due to preignition or ping as that call it.
