Base oil formulation containing (i) a Fischer-Tropsch derived light base oil and (ii) a Fischer-Tropsch derived gas oil. The formulation can be prepared by back- blending a Fischer-Tropsch derived light base oil with a Fischer-Tropsch derived gas oil, for instance derived from the same Fischer-Tropsch synthesis. Also provided is the use of a Fischer-Tropsch derived gas oil in a base oil formulation containing a Fischer-Tropsch derived light base oil, for the purpose of improving the cold flow properties of the formulation whilst maintaining its flash point above a desired target value, and/or for the purpose of reducing the concentration of a cold flow additive in the formulation, preferably with less of a reduction in the flash point of the formulation than theory would have predicted to occur due to the incorporation of the Fischer-Tropsch derived gas oil.

The air release rate of lubricating compositions is significantly enhanced when the composition is formulated with one or more vinyl aromatic-olefin block copolymers that forms a micelle-like structure in the oil. Compositions having the specified copolymers retain less than about 2.5% air after 1 min. at 50°C when tested by ASTM D 3427.

摘要:
An object of the present invention is to provide a grease composition for resin lubrication which is capable of keeping good the sliding lubrication between a resin member and a-metal member, and between a metal member and another metal member over the long term. The present invention provides a grease composition for resin composition which is characterized by including a base, a thickener, and at least one of a nonpolar wax and a polar wax. Further, the grease composition for resin lubrication is applied to a telescopic shaft for vehicle steering or an electric power steering apparatus, thereby to improve the durability, and to achieve a longer life.
