A lubricant composition is provided which mitigates the negative effect of zinc in ZDDP with respect to wear on timing chains by using in contact with the timing chain a lubricant composition comprising an ashless zinc-free organophosphorus compound and optionally zinc dialkyldithiophosphate, together providing about 50 to about 1000 ppm phosphorus, preferably about 300-800 ppm phosphorus, and more preferably about 500-750 ppm phosphorus; less than about 350 ppm to lower than &#x3c;1 ppm zinc from ZDDP; and at least about 100 ppm molybdenum from an organomolybdenum compound (preferably molybdate ester); wherein the Mo:Zn ratio is at least about 0.2:1 and the Zn:P ratio is lower than or equal to about 1.1:1; or in the alternative an organomolybdenum compound providing between about 300-700 ppm molybdenum, in combination with ZDDP providing zinc between about 200-800 ppm zinc, wherein the ratio of Mo:Zn ratio is at least about 0.4:1 to about 3:1.

Lubricant additive for reducing timing chain wear

A low-phosphorus lubricating composition having less than 600 ppm phosphorus, comprising at least 85 weight % of a lubricating base blend, and an additive comprising the following, as weight % of the total composition:

Ultra low phosphorus lubricant compositions

The present invention relates to an engine oil lubricant composition for use in internal combustion engines comprising one or more molybdenum containing compounds that deliver 1-1000 ppm molybdenum to the finished oil, one or more phosphorus containing compounds that deliver 25-650 ppm phosphorus to the finished oil, and one or more poly(meth)acrylate viscosity index improvers (VI improvers) that may or may not be functionalized, for improved fuel economy and turbocharger related deposits. In addition, the composition comprises an antioxidant system which is carefully balanced to provide improved fuel economy, comprising an aminic antioxidant, a phenolic antioxidant and an ashless dithiocarbamate. Additionally, the formulated oil may contain a dispersant poly(meth)acrylate, in addition to the PAMA VI improver, to reduce the amount of traditional succinimide dispersants.

Fuel efficient lubricating oils

A low-phosphorus lubricating composition has less than 600 ppm phosphorus, comprising at least 85 weight % of a lubricating base blend, and an additive comprising the following, as weight % of the total composition:

An antioxidant lubricant composition has at least 50 wt % of a lubricating base oil and

Lubricant antioxidant compositions containing a metal compound and a hindered amine

Novel molybdenum compounds are prepared by reacting a hindered amine with a molybdenum source, in the presence of one of (a) water, (b) a diol and water, and (c) the reaction product of a fatty oil and a multifunctional amine, and water. Lubricant compositions containing these new compounds are more stabilized against oxidation and have improved friction reducing properties. Synergy is observed when the novel compounds are combined with a diaryl amine in a lubricant composition.
