85 Octane

Hi Scotty and others,

I live in Utah and our base octane gasoline is 85 octane.  Why is this?  What is the advantage or disadvantage?  Most vehicles recommend 87 octane, is there anything that would cause this octane to harm a vehicle?

Thanks for your attention.

Utah has cities that are 10,000 ft high.

When the air is less dense, car engines can use fuel with lower octane.
