Barring a really bad commute or a mechanical problem, every car can get EPA estimates. Driving style has a ton to do with mileage. Also, increasing tire pressure can help too.

I suggest you keep at it. The VUE greenline isn't exactly the best example of a hybrid, but don't let that discourage you. Keep pushing for better mileage.
