I seem to be going through a lot of DEF in the 3.0 diesel. 12000km and I have gone through a few tanks already. Anyone else with this issue?

so the more u are in the gas and the more that motor is working the more sut it is gonna create. The more sut it creates the exhaust gets dirtier faster and has to clean more often. The more it cleans the more it uses. Keep in mind u can't compare it to a cummins in a 2500 application. The v8 gas in that truck makes similar horse power/tq.. so that motor still work a decent amount to move it. but when u compare the 2500 gas and diesel.. the diesel makes double the torque.. takes it very little effort to get it Rollin and keep it moving. just something to think about.

you never know there could be something wrong with it.. never hurts to have the dealer check it.

I think I will monitor it more closely in the next couple months and get a better picture of what its actually using. Then go to the dealership if its still using more than I thought. I was told to expect about 10000km out of a tank.

I drove it throughout the summer and now into the winter. Doesnt seem to be much difference. Recent temps have been -20c.

Did a search the dieselmag article stated it was 8 gallons ~30L so even more than you might have thought it was using sadly.
