I have a 2000 TDI Beetle with 240K miles. I get on average 43-46 mpg. I drive 115 miles to work one way, 230 round trip. I live in Southeastern Utah and work in Southwestern Utah.

Anyways, I start out at 4700ft and over 45 miles work my way up to 7100 feet and then back down to 6800ft as my final destination...and then the reverse when I go home.

I keep my tires inflated to 40 psi and check them regularly, keep the speed below 65mph, but I still cannot crack 50mpg, as some others are with these TDI's. It is a beetle and does have some bad aerodynamics, I am thinking about an "Ernie" Wing.....but would this altitude and the multitude of hills decrease my mpg that much? Roads are quite rough in some spots as well.

Any help is appreciated.
