I just fill up with what’s available and
go. 91 is everywhere in Okla. sometimes in small towns you will find only 87 so I just get it and go. I usually fill up at half tank and I’ve never had an issue.

Not an octane booster but claims it boosts octane.

Default octane

91 octane in most states does not have ethanol blend. 93 octane in all states has ethanol added.
