Well, the early ones had crank issues, if you made it past 15,000 miles yours wasn’t one with the issue. My good buddy complained his was eating oil, he tows a trailer that delivers three golf carts at a time, not exactly a giant load. The start of my oil consumption test is I have to change the oil and put it to the top of the hash marks on the dipstick. He called me two weeks later asking what I did to fix his truck. I replied nothing. I think oil consumption issue is depending on the oil you’re using, we use the dexos oil, explicitly at the dealership. I don’t know what he was changing his oil, but we run our wheel consumption issue went away. His truck is the only truck that I ever heard of a 6.6 gasser eating oil. A lot of other Chevy engines have oil consumption issues. But his was the only 2500 gasser that I’d heard of.
