2016 Ford F-350 Crew Cab LWB Dually 6.7 Mileage

Our 6.7 liter truck mileage has dropped from the 14-16 mpg range on the highway to around 12-13 mpg when not towing. Truck has about 35,000 miles on it. We have seen mileage in town as low as 10.5 mpg...

First think go slap whoever suggested you use any oil type air filter!!! They are notorious for messing with sensors on newer diesel trucks and auto's with sensors in air intake.

They could deny you warranty for having a non approved filter.

There is NO reason to use such a filter on any of the newer diesel trucks!!!

Class Dismissed.
