high zddp in small engine oil?

Cylinder compression has nothing to do with pressure against the cam/ lifters/ pushrods/ valves.

Yeah good point.

Sounds like you can use the latest sp rated oil even for break in

That's pretty much what I did for the last 3 new predator engines I bought. But I think Walmart supertech synthetic 10,000 mile oil is sn rated.
I looked in the manualsame and they call for SJ, but it doesn't seem to matter.
