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.

That's spark knock.
If it is so bad that you are getting true compression knock, then playing with the timing won't help any......since the fuel ignites BEFORE the spark hits.
Thankfully that condition is pretty rare.
