Honda claims in the manual and website that they add 'stuff' to the factory oil to help engine break-in. Somewheres in this forum someone posted their oil analysis results from the 1st oil change, at around 7500mi. There IS stuff in the oil- molybdenum, I think? As I recall in the thread, nothing exotic that you can't add yourself at any time. Honda is not just blowing smoke. I can't speak as to exactly what Mo does for the engine, however.

I fear to tread further into the oil-change-interval wars. It's almost like religion or current politics- quite polarized, eh?
