Effects of Motor Oil Composition on Engine Wear 690774
A taxicab test was conducted to determine the effect of motor oil composition on engine wear. It was found that detergent-inhibitor treat, antiwear additive level, viscosity and V.I. improver type all affected wear in one or several engine areas. Moreover, it was shown that with an optimum balance of components, multigrade oils can be designed which are as effective in controlling wear as single-grade oils.
