91 is what we have here and it’s great. 91 Ethanol free is too rare and expensive.

Costco in my area has 93. With the 36 gallon tank I don’t intend to buy gas anywhere else.

Same here. I try to get Cosco premium every chance I get. Plus I try to fill up every week so that way I don’t spend as much each time.

Use Costco exclusively in all my vehicles. Supposedly top tier gas for quite a while now. (Won't pay a dollar more a gallon everywhere else.) Anybody had any issues that can definitely be pinned on Costco gas?

i have been running in my 2018 Raptor for the past 2yrs and no problem.

I run E-85. Only $2.40/gallon and it’s 100-105 octane.
BUT you have to have a tune and a fancy new high pressure fuel pump so you can burn through it faster!

Only premium. It’s not that much more.

Last time I ever pumped regular was when I rented a car.

Anyone measured the air fuel and knock/degree sensor on non tuned for different grades?
