I wouldn't run the 85 in cars..

I got 91 at Sams in Bullhead....did a small trip... 23.4 mpg.....filled up with Maverick 87...did same trip.....20.4mph.... hmmmmmmmmmmm. If it calls for 91 you should run it.

Its funny how gas changes through the states. Montana had 91 Ethanol Free at most stations and Red Dye diesel was really common.
Since being in AZ, think I saw 1 Ethanol Free in Havasu and no Red Dye anywhere. I run Red dye in a heater to save a few bucks over regular D.

I filled up with 85 coming through Idaho once. At the pump I wasnt sure what I was looking at. Made me a little nervous.
