Very Low Fuel Avg

[Brock]

Before we talk about the mechanics. How much weight do you haul? what's your gear ratio? what tires do you run?

Obviously you have a major issue... major!

I was hauling 140,000lbs with 411 gears in a mile out engine that was doing a regen 8 timed a day and I was getting 3.5mpg so unless your hauling heavy, you got yourself a certified lemon.
