I don’t think there is a regular 85 octane lowest in Nebraska is 87 octane. E85 is the ethanol version but your vehicle has to be able to use it.
Some 87 here can have small amounts of ethanol if it says so at the pump and that can be used in normal vehicles. Older cars pre2000 don’t run well with it and some with carburators can get vapor lock
