Abstract

An internal combustion engine crankcase lubricating oil composition has a phosphorus content of not greater than 0.09 mass %, a metal detergent additive system comprising one or more metal salts of organic carboxylic acids, and a viscosity index improver comprising a linear diblock copolymer, one block being derived from a vinyl aromatic hydrocarbon monomer and one block being derived from a diene monomer.

Claims (11)

1. An internal combustion engine crankcase lubricating oil composition having a phosphorus concentration, expressed as atoms of phosphorus, of not greater than 0.09 mass %, based on the mass of the oil composition, which composition comprises or is made by admixing:
(A) an oil of lubricating viscosity, in a major amount;
(B) a metal detergent system, as an additive in a minor amount, comprising one or more metal salts of organic carboxylic acids; and (C) a viscosity index improver comprising a linear diblock copolymer comprising least one block derivable primarily from a vinyl aromatic hydrocarbon monomer and at least one block derivable primarily from a diene monomer.
2. An oil composition as claimed in claim 1 wherein the linear diblock copolymer is at least one diblock copolymer comprising at least a polystyrene block and a block derived from isoprene, butadiene or a mixture thereof.
3. An oil composition as claimed in claim 2 wherein the linear diblock copolymer is at least one diblock copolymer selected from the group consisting of hydrogenated styrene/butadien diblock copolymers and hydrogenated styrene/isoprene diblock copolymers.
4. An oil composition as claimed in claim 2 or claim 3 wherein the diblock copolymer has a Shear Stability Index value of from 2 to 50% (30 cycles) and the polydiene block of the diblock copolymer comprises from 40 to 90 mass % derived from isoprene and from 10 to 60 mass %
derived from butadiene.
5. An oil composition as claimed in any one of claims 1 to 4 wherein the diblock copolymer has a Shear Stability Index value of from 5 to 25% (30 cycles).
6. An oil composition as claimed in any of claims 1 to 5 having a sulphated ash concentration of not greater than 1.0 mass %.
7. An oil composition as claimed in any of claims 1 to 6 having a sulphur concentration, expressed as atoms of sulphur, of not greater than 0.3, preferably not greater than 0.2, mass %.
8. An oil composition as claimed in any of claims 1 to 7 wherein the metal salts of organic carboxylic acids are overbased alkaline earth metal salicylates.
9. An oil composition as claimed in any of claims 1 to 8 further including one or more additives, other than (B) and (C), selected from dispersants, detergents, antioxidants, antiwear agents, friction modifiers, corrosion inhibitors, pour point depressants, demulsifiers and anti-foaming agents.
10. A method of lubricating a compression-ignited or spark-ignited internal combustion engine which comprises supplying to the engine a lubricating oil composition as claimed in any of claims 1 to 9.
11. The use of a viscosity index improver as defined in any of claims 1 to 5 to improve the cam and lifter wear in the crankcase lubrication of an internal combustion engine by a lubricating oil composition having a phosphorus concentration, expressed as atoms of phosphorus, of not greater than 0.09 mass %, based on the mass of the lubricating oil composition and comprising a metal detergent system as defined in any of claims 1, 7 and 8.
