I only drive 18-21 miles a day. So my fuel economy kinda sucks. I filled up with gas today and after hand calculating the mpg. I was at a whopping 12.9 MPG.

I drive 9 miles each way to work. My truck doesn't have time to warm up either. It's been pretty cold all week in Nebraska.

Last time I was on the interstate on a 200 mile trip I averaged 25.3 mpg hwy. @ 63-65 mph.
In the summer I avg about 16.8 mpg city.
