I've noticed just the opposite: I seem to get better mpg with my Insight at my normal elevations, which run from about 4500 to 9000 ft, than I do near sea level. But it's not really a fair comparison, as the driving is very different. The higher elevations include a lot of climbing and descending mountains, often on twisty roads, and flat stretches tend to have little traffic so I can cruise at economical speed.. Sea level includes a lot of California freeways, which are either bumper-to-bumper or going like a bat out of hell.
