IMPROVED LUBRICATING COMPOSITIONS |
摘要 |
Lubricating compositions particularly for crankcase lubrication of gasoline and diesel engines in automobiles and trucks have improved viscometric properties by the incorporation of an ashless dispersant and a dispersant viscosity improver with increased boron content of at least 0.02 wt. % of the composition, preferably in the form of an ashless dispersant borated to a higher level. |
