Lubricant additive for reducing timing chain wear |
| abstract |
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 <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. |
