A friend sold his boat and was cleaning out his garage and offered me some oil free! Of course i took it. Free is always the right price. Thirty quarts of racing oil. The problem is most of it is straight 50wt. Eighteen quarts pennzoil gt racing, api sg/cd, some valvoline racing 50wt sg, some valvoline vr1 racing 20w/50.
I'm about to break in a new solid flat tappet in a ring-and-bearing 440 for my old bracket car, and i was planning on using delo diesel 15w40 and lucas zinc additive for break-in, then the diesel oil after that. The question is- can i add a quart or two 50wt to the mix after break-in? I dont know how much if any zinc is in the 50wt racing. Im using a seven quart milodon pan, one quart low. Thanks for any help guys.
