Bought HP4 engine oil (please Read)

[brian400ex]

I had an older quart of HP4 engine oil laying and i bought a new quart today. The new kind doesn't have Moly while the older stuff has moly. Will it hurt to mix the two?

the new formulated motorcycle is designed more for clutches and engine, while the old stuff with the moly was made when they didnt know moly was not good for the clutch components mainly your friction plates i think, my advise dump the moly and spend the money and buy another quart of the new stuff.
