Some folks say abuse it from the start and sometimes it seems to make the engine quicker, or blow it up.

Personally I'd keep it 55 or under for the first 500, 65 for the next 500 . Let it run for a couple minutes after each startup, before driving.

When does the dealer recommend the 1st oil change?

The engine that came with the truck was supposedly already broken-in, but with this one you want to be sure the rings seat properly, so go with what the mechanic says.

As for the pcv info: Why don't they send that info to us all?
