Def

[f100cleveland]

Just wondering how much DEF the newer trucks use. Its not a Super Duty but my work truck has used over 280 gals of DEF. Its a 2012 Mack Granite dump truck with a 425hp Volvo engine. When its really cold and working it hard it drinks alot of it. It has averaged out to be around 195 miles to the gal. Seems high. How many miles to gal do the pickups get?

I have not heard any of the drivers talk about this, I will ask around, that does seam high to me also.
