Lubricant Composition |
| 摘要 |
A lubricant composition comprising from 75 to 95 percent by weight polyalphaolefin base oil; and from 7.5 to 25 percent by weight oil soluble polyalkylene glycol (OSP) additive, wherein the polyalkylene glycol has a viscosity at 40° C. from 15 cSt to 50 cSt and comprises units derived from propylene oxide and units derived from butylene oxide; wherein the lubricant composition exhibits a four ball EP weld load result of at least 160 kg and an air release value at 75° C. of less than 3 minutes is provided. |
