first off the corvette, cobalt ss/sc, trailblazer ss/sc all come from the factory already broken in. that info is from my foremans and all of my journeyman mechanics. you can not properly break in a motor on synthetic due to its properties. regular motor oil has something in it. i can't remember exactly what, but it helps seat everything properly
