Hello. I’ve read a few posts here about the oil consumption issue on some of these 3.0 Duramax. I am afraid my truck is one of the problem trucks. It tripped the low oil pressure code at 4100 miles. The dealership told me the oil level was fine, probably just a sensor. I took it home and let it sit for a few days, since my appointment to check it out was 3 weeks away. I decide to check the oil level myself. The dipstick was bone dry. I went and bought the correct oils and added 3 quarts and checked oil as I added. It ran just fine. I took it the dealership and complained. They did give me a complementary oil change and I thought that was that. I thought maybe the oil was low from assembly. Well now 2000 miles later, I checked the oil because I am going on a 1500 mile trip. The dipstick is again bone dry. The dealership claims that they’ve never seen this issue.
