I live by the “all because it CAN run on 87 octane, doesn’t mean it should “
I personally use 93 octane. And realistically it’s not much more in price (in my area).
It may also come down to the modifications you have on your machine.
Though everyone has a different opinion about octane ratings and the use of them in their machines. I MAY not be getting any benefits from the 93 but I’m ok with it. And if I am getting an edge or benefit, then great. Either way I’m happy.
