Abstract: The influence of additives X and Y on the filter property of 8 kinds of base oils, the influence of the content of each single agent and cosolvent in additives on the wet filter properties of base oils, and the relationship between wet filter properties and average particle size of emulsion were studied. The results showed that the dry filter properties of the 8 base oils decreased slightly, while the wet filter decreased significantly. The main component that makes the wet filter property of base oil process worse was the cosolvent of additive, tetraethylene glycol monomethyl ether. After adding additives, the bigger the average particle size of the emulsion formed by the base oil, the worse its wet filtering property. The higher the content of ether cosolvent, the worse the wet filter properties.
