摘要： Certain citric esters and amides, and certain mixtures thereof, e.g., mixtures comprising citrate oligomers, exhibit excellent anti-wear activity in lubricants. Many of these compounds or mixtures of compounds also exhibit a high degree of anti-wear synergy in combination with zinc dihydrocarbyldithiophosphates. The compounds of the invention are thus valuable tools that can allow one to reduce the amounts of zinc, and phosphates, that are used in the lubricant without sacrificing anti-wear performance.

摘要： An improved organic and molybdenum friction modifier combination is disclosed, the combination resulting in a synergistic result of both initial friction reduction performance and a further retention and durability of continued friction reduction performance. These results will produce added benefit from, e.g., formulated passenger car motor oils targeting lower viscosity formulations to help improve fuel economy.
