the moly that is found in a UOA from the first 5K miles of a new honda engines life is not so much in the oil-to begin with at least.
Certain Honda engines use Molybdenum as afriction coating on the skirt of the pistons (and other places as well) and this is esp. true on the B16A2 DOHC VTEC engines (as well as all other B-series VTEC engines). Inital wear causes an elevated level in the first oil change and there is some moly in the break-in oil too.
THis is not a miracle oil that will determine whether or not your engine will last 20K miles longer, but it may make a difference whether or not the piston rings seat well.
I had a 99' Civic Si(r) w/ the B16A2 160hp engine (redlined and made power all the way to 8000rpms:
) and i changed my oil at 600mi. and noticed at high revs some black puffs of smoke. My friend tried to tell me that it was from not elaving in the break0in oil longer but, her had it too as these engines have a lot of valve overlap and thus, causes some blck puffs at 7000+rpms.
however, i did have allot of consumption w/ this engine and would lose up to 1.5 quarts in 3K miles. After this started to happen I believed my friend and still kinda do. Id leave it in until 3K miles and youll be okay. Heck, even 1500miles, but not 600miles. nope.
