  • Method of improving the fuel economy characteristics of a lubricant by friction reduction and compositions useful therein
    Patent number: 5736491
    Abstract: A method of improving the fuel economy characteristic of a lubricant by friction reduction including mixing the lubricant with a C.sub.2 to C.sub.12 aliphatic carboxylate salt of molybdenum and a zinc dialkyldithiophosphate or zinc dialkyldithiocarbamate is disclosed. The synergistic interaction of the aliphatic carboxylate salt of molybdenum and the zinc salt results in at least a 30% reduction in the coefficient of friction at 100.degree. C.
