I'd like to get my Duramax oil analyzed also just to see if it really needs the changing when the computer on the dash says it does! Or if the service manager is just pulling my leg on the mileage deal. I change mine about every 7-8000 miles anyway but I'm not towing the Monte all the time either!

My dealer swears by the DIC and I know he's not after my money, because I change it myself. Like you, I do it around 7,500 the DIC usually says I have about 25% of time remaining at that point.
