Definitions
- the invention provides a lubricant composition having a kinematic viscosity at 100°C of less than 12.5 mm 2 /s and a HTHS viscosity of at least 3.5 mPa.s at 150°C and a shear rate of 10"/s, which composition comprises, or is formulated by blending :
- any suitable base oil may be used provided it meets the requirements of having a kinematic viscosity at 100°C of 2-8 mPa.s and a VI of at least 120, preferably from 120 to 160.
- the base oil is selected from one or more of synthetic oils, hydro- isomerised petroleum-derived hydrocarbons, and hydrocracked petroleum-derived hydrocarbons, or a mixture or one or more of these base oils with a mineral, vegetable or animal oil, preferably mineral oil. It is preferred that the base oil is either one or more synthetic oils.
- the mineral oil is preferably selected to have a kinematic viscosity at 100°C in the range from 2 to 8 mm 2 /s.
- suitable mineral oils include petroleum-derived mineral oils which have been refined, for example, by acid refining, solvent refining, hydrotreating and the like.
- the mineral oil component is a conventional mineral base oil, such as solvent neutral base oil, but may also be a more highly refined base oil, for example, a white oil, or maybe a mineral oil derived from alternative sources, for example, oils derived from coal tar or shale.
- the copolymer is a random block copolymer meaning that it is formed of blocks of monovinylarene homopolymer and blocks of copolymerised (poly monovinylarene- conjugated diene).
- a preferred copolymer is styrene-butadiene copolymer, that is a copolymer formed by copolymerising styrene and butadiene to form a styrene- butadiene/styrene (SBS) block copolymer. Further details of such copolymers and their methods of manufacture are given in EP-A-081852, the disclosure of which is incorporated herein by reference.
- An example of a suitable SBS copolymer VI improver is Glissoviscal PG (trade name) supplied by BASF.
- the lubricant composition according to the invention may be used in any application where lubrication is needed, provided it meets the requirements of that application. However, it is especially suitable for internal combustion engines, including both gasoline and diesel-fuelled engines.
