At the dealer new owner orientation, my dealer said to not worry about changing the oil until the oil life monitor tells you to. My 2500 has 4300 miles and still no indication. I got nervous and changed it anyway, being that it was the first change.
The question is, "How many miles did your Avalanche have on it before the DIC told you it was time for a change?" Please post your Avalanche model too (1500 or 2500).
