Two-phase lubricating oil composition |
| 摘要 |
Lubricating oil compositions are provided herein that comprise a mixture of: (A) a hydrocarbon as a low-viscosity constituent, (B) a polyalkylene glycol (PAG) as a high-viscosity constituent wherein the oxygen/carbon weight ratio is in the range of from 0.450 to 0.580, and (C) a compound as a control constituent wherein the oxygen/carbon weight ratio is in the range of from 0.080 to 0.350. Methods of lubricating a surface using such lubricating compositions are also provided herein. |

1. A lubricating oil composition comprising a mixture of:
(A) a hydrocarbon as a low-viscosity constituent, (B) a polyalkylene glycol (PAG) as a high-viscosity constituent wherein the oxygen/carbon weight ratio is in the range of from 0.450 to 0.580 and the density at 20° C. is in the range of from 1.000 to 1.050 g/cm3, and (C) a compound as a control constituent wherein the compound comprises one or more ester groups and has an oxygen/carbon weight ratio in the range of from 0.080 to 0.350. |
