HEY you guys/gals.. what about a happy middle of the road approach. Lets say we with flat tappets can/could use a product like Cranes Super Lube Break-in Concentrate part number 99004-1 "zinc rich" with each oil change. The company states that it is to be used during break-in periods. Can it be used at every oil change? I'll send them a RFI unless one of you already has the answer?...We are ALL just trying to the best for our trucks....Steve
