I'm about to complete my short block rebuild. I was going to start out with Mobil 1 synthetic oil and Slick 50. But, I was advised not to install synthetic until I change the oil at 500 miles because it would be a waste of money. And, not to install Slick 50 until 2nd oil change at 3000 miles, to give the rings a chance to seat correctly. What do you guys think? Take care.
