Zinc dialkyldithiophosphates (ZDDP) are the most important group of ash-containing AW additives, offering not only outstanding wear protection but also antioxidant properties that contribute to extending oil lifespan. The structure of the alkyl groups significantly influences the stability of ZDDP and their AW/AO performance, making the choice of the right ZDDP critical. With LUBIO® AW 1, we offer a versatile all-rounder with an optimal balance of reactivity and stability. However, we also have more thermally stable or reactive ZDDP variants in our portfolio.
