| titleOfInvention | Multi-functional lubricating fluid |
| abstract | The present invention relates to multifunctional lubricating fluids that can be used in the various members of self-propelled vehicles, in particular in the engine, the transmission or the hydraulic circuit and relates to a lubricating composition comprising at least one base oil of groups I to V, and a mixture of at least two polymers having a difference in Shear Stability Index (PSSI), measured after normalized test KRL 20 hours at 100 ° C of at least 25, and having a viscosity profile such that: (1) the viscosity of said composition, measured at 100 ° C, after Bosch-30 cycles test according to CEC-L-14-A-93 representative of the engine shear conditions, is between 15.0 and 20.0 cSt for a grade 50; (2) the viscosity of said composition, measured at 100 ° C after KRL shear test 20 hours according to CEC-L-45-A-99 representative of shear conditions in gearbox, is between 11.0 and 14.0 cSt for an oil starting from grade 50; (3) the viscosity of said composition measured at 40 ° C after KRL shear test 3 hours, according to CEC-L-45-A-99, is between 61 and 75 cSt for a starting oil of grade 50; in which the polymers of the mixture are chosen from polymers of the viscosity-improving type preferably chosen from poly-alpha-olefins (PAO) with a kinematic viscosity at 100 ° C. of greater than 90 cSt, polyisobutenes (PIB), Polymeric esters, olefins copolymers (OCP), homopolymers or copolymers of styrene, butadiene or isoprene, polymethacrylates (PMA) and optionally among the type of pour point-type polymers preferably chosen from polymethacrylates ( LDCs). |
