    Anyone living up in the mountains run 85 instead of 87? Depending on time of year I live at either 4500 or 9000 feet, and if I can save a few dollars running 85 at high altitude (if it truly doesn't matter) then that's more money for tires, lights, etc. Anyone have personal experience running 85 octane long term?
