I am going to take a photo to prove the it can be done..its all how you drive.

I have a 40 mile round trip commute to work 50/50 city/highway and in the summer time I WILL hit 300 before I fill up every time.

In the winter time with winter fuel I cant do it I may see about 260-280.

My city speed is 40-45 mph and I never go over 65 mph on the interstate. Ease off at the lights and brake ahead of time to roll to the lights, stop signs whatever....lol.

I've followed my fuel mileage for a long time and I see 17-19 mpg every fill up.

2000 4x4 Auto @ 89000 miles.

On a good note I used to commute 6 days a week, my new position I commute 3 days a week
