Ok I'm really confused. Regular gas is 87 octane. 85 is not 87 octane Nor is 87 85 octane. You will see 85 octane at higher altitudes in parts of the west as a substitute for 87 octane regulars gas but .... remember what goes up also comes down.
We run most of our high RPM 2 cycle engines, for example a chainsaw, and they perform better at altitude 7,000'.
