Abstract (en)
[origin: WO2013164449A1] The present invention concerns engine lubricant compositions comprising at least one base oil, at least one polymer viscosity index improver and at least one polyalkylene glycol, obtained by polymerisation or copolymerisation of alkylene oxides comprising from 3 to 8 carbon atoms, including at least one butylene oxide, the quantity of polyalkylene glycol being 1 to 28% by mass relative to the total mass of the lubricant composition. Using at least one polyalkylene glycol, obtained by polymerisation or copolymerisation of alkylene oxides comprising from 3 to 8 carbon atoms, including at least one butylene oxide, in a base oil, improves engine cleanliness while not increasing, or indeed while decreasing, the consumption of petrol or diesel fuels by the engine.
