just run whatever has been in there, the gm shit for coolant... oil run regular 5w30 until about 1000-1500 miles.. it'll scrub off any leftover metal in the car.

I've always been in the habit on a fresh motor to change the oil at 50, 100, 500, 1000, 1500 miles

after that a nice synthetic is always lovely like redline or mobil1 or royal purple...

spark plugs on a boosted motor NGK TR6's work wonders.
