"The problem with doing mileage tests over a short distance like this is that if during the test the Duramax happened to do a DPF regeneration and the Ford didn't the results are meaningless. I think it takes roughly a gallon of fuel to clean the DPF so on a run where only a few gallons of diesel is required the mileage result could be way off."
When the particulate filters fist came out it seemed that everyone doing a test would go to great lengths to trigger a regen before starting the test. I don't see that anymore are have wondered how that affects the test data.
