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.

ONLY as long as you STAY at high altitude.
I has something to do with atmospheric pressure and air density.
85 stays 85 no matter what you do.
And when you hit the valley, it's not quite enough.
But not likely to cause a major problem either.
