So last last week I had to do a road trip. Left central Michigan for Phoenix Thursday Friday then return back to Michigan right away on Sunday Monday, total 4,500 miles driven. While stopping for gas I noticed many of the gas stations sold 86 octane fuel once I got past say Texas. I thought 87 was the standard for the USA. Any one know why states out west sell 86?
BTW I was driving a 2023 Equinox average mpg was 32 worst was 23, best was 40 plus while driving thru Texas with a huge tail wind.
