Some of us suspect that since he (gpsman1) is in Colorado, he probably drives down hill (both ways

If you use the techniques described in the FAQ, with a lot of discipline, you can significantly increase your miles per gallon, but it takes practice and patience.
I've had my FEH almost a year, and am still learning new tricks to increase my mileage. In very cold weather, I've learned to get my hybrid battery temp up to 15 deg C by using Low Gear.
