I will be moving in a few weeks to a town at about 5,000 ft elevation. I will continue to use 87 in the Burb because we will need to make periodic runs to a city at about 2,800 ft elevation to make Costco runs every two or three weeks and don't want to have to worry about what's in the tank, particularly because all trips other than those 90 mile hauls will likely be 5 miles or less so a tank may last the entire time between such trips. And I will continue to run premium (whatever that may be) in the GP because of the supercharger.
