Zn is an anti wear additive and detergent, whereas Moly is a friction modifier.
They are used together in some oils.
They do different things. Dr Google will explain.
This paper suggests they may not be compatible, having the effect of increasing engine deposits:
From:
https://link.springer.com/chapter/10...642-33841-0_35
'Generally, molybdenum dithiocarbamate (MoDTC) is added into engine oil as an effective friction modifier to improve fuel economy. Zinc dialkyldithiophosphate (ZnDDP) has also been used as a multifunction additive in engine oils for more than 50 years. However, the results of this study showed that the coexistence of MoDTC and ZnDDP in engine oil could cause deposits accretion of the oil in the TEOST 33C.'
Could and might?
And so on.
