Abstract: Although the lowering engine oil viscosity is effective to improve the fuel efficiency of automobiles, its research has not been advanced because of the concern about a plain bearing lubrication. The plain bearing performance was evaluated with low viscosity base oils using a newly developed apparatus which enables the simulation under the automotive conditions. As a result, it was found that the friction coefficient and the contact condition between the plain bearing of Cu-Pb alloy and the shaft were different from that of Al-Si alloy. It is important to consider the plain bearing materials for the design of engine oils.
