Are their oils with molybdenum in them to seal it even further? Sorry if this is an idiotic question, just want to enhance my limited knowledge.

Rep Power: 401 From the factory, manufacturer's use their OEM oil plus several addatives including molybdenum (i believe it's molybdenum disulfide) to help the engine break in properly. You want to leave this oil in for a good 5000 miles before you change it out. Once you're past the breakin, you really don't need the amount of molybdenum in your oil that was in it from the factory. There are moly addatives you can get out there, but even most of them say "beneficial to newer engines" on the bottle. Soluble molybdenum is used during the breakin to assist in the amount of heat the engine is producing. (a new engine runs at a somewhat higher than normal operating temperature during breakin) Moly helps dissipate that heat, as well as smooth out the surfaces of everything in the engine during the breakin period.
So just use whatever oil suits your needs best, and IMO, dont worry about adding molys.
