I just changed the oil in my 2010 6.2L today. It looked pretty clean on the dipstick and I was hesitant. Just under 3000 km which is approx 1850 miles.
Well when I looked in the drain pan, which included what came out of the filter, the oil did look dirtier, and I was glad I changed it.
I used the AC filter PF48 and GM oil this time, dealer gave me a good deal when I bought the truck on some filters and oil. On my 2007 and other vehicle I have always used mobil 1, but I am thinking I may switch to some other syntehetic, such as Penzoil platinum or Castrol Syntec. I'll have to do some research on Bob's oil site, and see what the latest is.
As a note to anyone with the 6.2L, I loosened the oil filter and then let it drip out until I finished removing it, seemd to let a lot of oil out, more than my 6.0L did in the past. Now as far as the oil drain plug is concerned, I knew to have the edge of the drain pan as far as I could over from the plug, and wow did it shoot far over from the pan plug, seemed a lot more furhter than the 6.0 L had done previously and I did a lot of oil changes on that vehicle. It's a 15mm wrench for the drain plug.
So my view is change it, but be careful.
