LUBRICATING OIL COMPOSITIONS |
| 摘要 |
A lubricating oil composition having a sulphated ash content of less than or equal to 1.2 mass % as determined by ASTM D874 and a phosphorous content of less than or equal to 0.12 mass % as determined by ASTM D5185, which lubricating oil composition comprises or is made by admixing: an oil of lubricating viscosity, in a major amount; an oil-soluble or oil-dispersible polymeric friction modifier as an additive in an effective minor amount; and, an oil-soluble or oil-dispersible dihydrocarbyl dithiophosphate metal salt as an additive in an effective minor amount. |

1. A lubricating oil composition having a sulphated ash content of less than or equal to 1.2 mass % as determined by ASTM D874 and a phosphorous content of less than or equal to 0.12 mass % as determined by ASTM D5185, which lubricating oil composition comprises or is made by admixing:
(A) an oil of lubricating viscosity, in a major amount; (B) an oil-soluble or oil-dispersible polymeric friction modifier as an additive in an effective minor amount, the polymeric friction modifier being the reaction product of solely:
(i) a functionalised polyolefin;(ii) a polyalkylene glycol;(iii) a polyol; and,(iv) a polycarboxylic acid; and, (C) at least one oil-soluble or oil-dispersible dihydrocarbyl dithiophosphate metal salt as an additive in an effective minor amount. |
