Method for improving fuel economy of lubricating oil by reducing friction and useful compositions thereof

摘要

The present invention provides a friction reduction comprising mixing an aliphatic carboxylate salt of 2 to 12 carbon atoms (C ₂ to C ₁₂ ) of molybdenum and zinc dialkyldithiophosphate or zinc dialkyldithiocarbamate and a lubricant. The present invention relates to a method for improving fuel economy of lubricating oil. The synergistic interaction of the aliphatic carboxylate and zinc salts of molybdenum results in at least a 30% reduction in the coefficient of friction at 100 ° C.
