thats not far from normal. I had a gmc jimmy 2wd with the 4.3 and it averaged 15mpg. It ran great, and thats just how it is. On an all highway trip with moderate speeds you might approach 20mpg. Also AcDelco plugs are best for these motors, not Bosch.


I'm getting 200 miles to a tank of gas and less then 6 months ago I was getting 350 to a tank. We do 90% freeway driving at 70-75 mph
