Definitions
- the present invention relates to lubricating compositions for gasoline engine or diesel vehicle engines, allowing a reduction in the fuel consumption of said vehicles.
- Frictional energy losses between the various engine components occur, depending on the engine parts, either in hydrodynamic, elastohydrodynamic, or limit friction regimes.
- the formulation of a fuel-saving engine lubricant is not limited to the selection of these different components independently of each other.
- the interactions between the different components must be taken into account, and the other lubricant performances, such as the stability of the viscosity, the inhibition of the corrosion, the dispersing power ... must not be altered.
- engine lubricating compositions for achieving fuel economy can be formulated by the combination of GTL-type bases, with organic friction modifiers of fatty acid esters and polyols type, and VI-improving polymers of polybutene type, ethylene propylene copolymers, polyacrylates or polymethacrylates, AB Block copolymers obtained by copolymerization of diene such as butadiene and isoprenes with vinyl aromatics such as styrene.
- compositions are for example disclosed in application WO 2008/124191.
- Such bases have the disadvantage of a high cost and it is desirable to develop an additivation to formulate lubricants fuel savers or fuel eco (FE) with mostly conventional bases.
- Organometallic friction modifiers may also be associated.
- the application EP 2078745 thus discloses a lubricating composition for petrol and diesel engines, associating molybdenum dithiocarbamates and zinc dithiophosphates, and making it possible to obtain fuel savings in vehicles equipped with these engines.
- Eco-fueled motor lubricants comprising a mixture of organo-molybdenum friction modifiers such as molybdenum dithiocarbamates, and organic friction modifiers such as monoesters of fatty acids and polyols are described in application WO 2004/053033.

- DTCMo organomolybdenum friction modifiers
- VI-improving polymers of polymethacrylate, polyolefin, styrene type. diene copolymers optionally in combination with VI-improving polymers of polymethacrylate, polyolefin, styrene type. diene copolymers.
- the fuel savings achieved by the engine lubricant must be evaluated globally over an entire standard engine cycle representative of the average conditions of use.
