    摘要: The embodiments described herein relate to particular formulations and methods that provide reduced engine deposits. The lubricant composition includes a base oil having a NOACK volatility of from about 5 to about 15 and a zinc dialkyl dithio phosphate composition. The zinc dialkyl dithio phosphate composition has at least about 65 mole percent of zinc dialkyl dithio phosphate compounds derived from all primary alcohols, wherein the zinc dialkyl dithio phosphate composition has greater than about 40 mole percent zinc dialkyl dithio phosphate compounds having alkoxy moieties derived from alcohols having four carbon atoms.
