i drive a ford ranger, it is alot smaller but has the same type of aerodynamics and weight for size. I have found that slowing down alot saves money, it bumps me us a few mpg. When i drive on the highway, im always in the right lane and always way under (55, assuming safe) If you go slower than traffic then when the vehicles pass you their waves they create in the air "push" you along saving you money too. Hope you get you mpg higher.
