Yes. I was aware of emissions/converter durability being the driving force behind it all. The disappearance of flat-tappet cams from new car engines made it possible (and probably cost-effective, overall) to make the change-over.
I was not aware that any mfr was specifically running a high-ZDDP oil during the break-in interval (but it certainly makes sense). Thanks.
Now you've got me wondering if you might be able to source the good stuff for your pushrod, fresh rebuild, or race engine at the local Honda store.

Not sure if you are a fan of Royal Purple, this is a Royal Purple Thread after all.....they make a product specifically for breaking new motors and their product description says "especially for motors with flat tappet camshafts" it also names Zinc as an ingredient.

No basis for opinion - I can't remember ever seeing RP in any of the local stores.
Although I've always used GM's EOS (EO$$$?), I'm not so dedicated to it that I wouldn't consider using the RP break in lube, although I won't ever go back to a flat-tappet cam. The guys over in the Classic section might be interested.
