Message	content of more than 1,200 PPM for break-in; also non-synthetic oil before switching to synthetic. But most of the preference for using zinc is to prevent wear between the cams and lifters during break in and yours are not new. Personally, I think how you break in a rebuilt engine is more important than the oil you use. Lots of good advice out there, but basically run it 2500-3500 for extended periods with no load. There's a suggested patterned sequence of run ins before you actually get out onto the roadway and drive indiscriminately. Search is your friend. _________________________________________________
