- the present invention is applicable to the field of lubricating compositions, and more particularly to the field of lubricant compositions for marine engines, in particular for four-stroke or two-stroke marine engines, preferably for four-stroke marine engines, or for stationary engines. More particularly, the present invention relates to lubricant compositions whose use promotes fuel savings (Fuel Eco or FE or Gaz Eco or GE) and having good properties in engine cleanliness, especially cleanliness crankcase. The present invention also relates to a method for reducing the fuel consumption, in particular of fuel oil, of a ship or a plant using this lubricating composition. In the automotive sector, because of environmental concerns, there is a growing interest in reducing emissions and saving fuel.
- engine lubricants for automobiles have an influence on these two phenomena, and engine lubricants for automobiles called "fuel-eco" (in English terminology), have emerged. It is mainly the quality of the lubricating bases, alone or in combination with viscosity index improving polymers and / or friction modifying additives, which gives the lubricant its "fuel-eco” properties.
- the fuel savings generated by "fuel-eco” engine lubricants are essentially achieved during the cold start, when the engine is not yet in stabilized mode, and not at high temperature in stabilized mode.
- consumption gains in the NEDC (New European Driving Cycle) cycle according to European Directive 70/220 / EEC are cold (urban cycle) of 5%, hot (extra cycle). -1.5%, for average earnings of 2.5%.

- lubricating composition for a marine engine or for a stationary engine which allows reductions in the consumption of fuel (fuel and / or gas), in particular fuel, which are satisfactory, while maintaining the other performances of the engine.
- lubricant composition in particular the cleanliness of the engine, more specifically the cleanliness of the crankcase.
- a lubricating composition for a marine engine or for a stationary engine having good thermal resistance under severe operating conditions, and more particularly in the presence of fuel (fuel and / or gas), particularly fuel. Indeed, during the combustion of the fuel or gas within the engine, residues and unburnt combustion can pollute the lubricant composition and thus alter its thermal behavior and its detergency properties.
