Get to cooking Fred! Like Bludawg said, no need to waste fuel on seasoning. Maybe wash it out with warm water and Dawn, in the event there may be residue from the manufacturing process.
I have never cooked on a new WSM, so mine all get a thorough washing before I cook on them.
BTW, you are going to love the ease of cooking on a WSM. Great pits.
