They recommend running Joe Gibbs Driven BR 30 oil for the first 400 mi, which I am doing. After 400 mi change out that oil and just run conventional 10 W 30 oil. Never anything synthetic. Don't baby the engine but don't go to hard on it. They actually recommend getting it checked for emissions right away to tell if something is out of the ordinary, like a sensor that went bad, or the cat. Setting the timing is critical, I'm good on that there is no pinging just straight up acceleration. The issue with doing the emissions test right away is that, if it doesn't pass your truck is labeled as a gross polluter, and you have to go to a star test only station, they can't tell you why your truck didn't pass. I did get the guy to mention that the cat may be the issue. I am having my shop take a look at the numbers Monday, and then go from there.
The engine is not full broken in until about 2000 mi. If I remember correctly, I talked to them on the phone about recommendations. They also recommend running the engine for 15 min at 1,300 rpm, and 20 min at 1,800 rpm.
