Contrary to the above...
Driving in mountains does not improve MPG, unless they are Florida mountains.
Much above 1,000 feet, the mixture will get progressively richer until the exhaust is smoking like a diesel.

Addis Ababa is the same altitude as Denver. We used the smallest jets we could buy and they could have been still smaller.
If you spend appreciable time at altitude, Mike, change jets. Also, because of the temperatures you ought to switch all the lubricants to Amsoil, which could improve MPG.
I use and talk about, but don't sell Amsoil.
