I have 1500 miles on my new 2500HD, and I'm going to change the oil. I've been a hot rodder for 35 years now. The question is not about my timing on the oil change, but the oil that is the best for this new engine. What is everybody using? How long have you used it? Is there some oils to stay away from?

I hope I've asked all the right questions, I'm sure there's a boat load of information in everybody's head in this forum, so thanks in advance.
