Sabrina,

This morning it was cool (in the 40's) and it took me about 10 mile to get the ECO gauge above 35 on 45 miles per hour roads, but in the afternoon it was warm (in the 70s) and it only took me about 3 miles to max out the ECO guage. I think you will see much better mileage in the summer half of the year. During the winter all cars run richer to deal with the cold temps. I'll bet a Jetta wouldn't come near 25 mpg on a short commute in a MN winter as it would never get to full operating temp either. You are probably getting a little better mpg on your daily commute and a lot better on any trips or errands around town. Enjoy your car and when the plug-in hybrid comes to the marketplace trade up, you may never have to buy gas again!
