ABSTRACT:
Novel zinc additives are provided which function as antioxidants and extreme pressure agents for lubricants and possess high thermal stability. In addition, they exhibit good filterability performance and good corrosion resistance. The zinc-containing additives are formed by admixing (i) at least one zinc dialkyldithiophosphate wherein each alkyl group contains 6 to 12 carbon atoms and is branched on its beta-carbon atom, and (ii) at least one zinc alkanoate wherein each alkanoate group is branched on its beta-carbon atom, in a ratio of 6.0 to 8.0 equivalents of (i) per equivalent of (ii).
