85 octane regular gas mid west states?
I will be driving car to Wyoming from Tennessee. Will I encounter 85 octane for regular gasoline? Hard to find 87 octane in Midwest? Thank you for any help you can provide.

In the Black Hills area of South Dakota, most gas stations have 85, 87, and 91 octane fuel. Their REGULAR grade 85 octane fuel does NOT contain ethanol so it costs more :? then their PLUS grade 87 octane fuel which contains 10% ethanol. The PREMIUM grade 91 octane fuel also contains 10% ethanol.
