Who is "they"? I don't know about the Duramax, but every GM vehicle I've driven in the last ten years has an oil life indicator. It's very simple: you wait until the oil life indicator tells you to change the oil.
If it's the clowns at the oil change place telling you to change every 3000 miles, consider their motivations. Let's take my wife's Trailblazer, for example. It takes 7 quarts of oil per change and I have to change the oil about every 15,000 miles. If I changed every 3000 miles I'd be buying an extra 84 quarts of oil every 15,000 miles or .0056 quarts/mile. So driving 20,0000 miles per year that's 112 quarts of oil per year. If an oil shop's markup on synthetic oil is 2 bucks a quart, they stand to make an extra 224 bucks a year by convincing me to change every 3000 miles. (Actually I do my own oil changes, but at the current price of Mobil 1 it's still ridiculously expensive to do an oil change.)

Dad bought the 202 new in 1962, and I recall quite clearly going to the dealer with him to sign for it.
