When the dpf is deleted people are typically claiming a +5MPG improvement on ford 6.4L and 6.7L Cummins guys are claiming a 2 to 4 mpg improvement. Even ford claims that a dpf regeneration cycle can use up to 17 liters of fuel.Q
Nothing I have found any where supports the claim that the dpf system does not hurt fuel economy.
The dpf system on a diesel is nothing like the catalyst system on a gasoline engine. I believe that the converter on a gas engine has little to no effect on fuel economy.
If you dont live some where smog is a problem then getting over all lower fuel economy and burning up to 17l of fuel to reduce NOx, make your diesel particulate smaller and more harmful is irresponsible.
