I own a 2007.5 LMM with 60000 miles each time I change the oil and filter the oil life gets shorter and shorter it has 2000 miles on it since i last change the oil and the DIC has said to change it three times within the 2000 miles my dealer does not evan know what is going on with it and yes I reset the oil life indicator each time I change it frustrated in Florida

 

What do you mean by shorter? There is less over a period of time? It doesn't last as long? It turns blacker sooner? You may have some sort of electrical ground thats setting off the sensor or you may have a more serious problem causing your truck to leak oil.

 

the dang dpf stuff

 

thats what I am thinking DPF crap
