Stop in for a cup of coffee

OK serious question new pistons, rings and main and rod bearings, re built oil pump (guts) run break in additive in the oil at first? Or is that just for cam changes? I am so confused!


I believe the break in oil is for the break in of new cam and lifters... But not completely sure....

It won't hurt to use it for the first start and break in the cam and lifters JIC....


When it comes to oil/lube, it's best to error on too much vs not enough.... (Just ask her... :D)
