NOVELTY - Creating an additive system to reduce wear and friction for lubricating oil based on modified graphene and modified silver nanomaterials, comprises: (i) generating graphene modified with oleyamine; (ii) generation of modified nano with oleyamine and oxalic acid; and (iii) create an additive system by mixing modified graphene and modified silver nano into the base oil, in which this additive system contains 10 g/l modified graphene and 0.8 g/l modified silver nano. USE - The method is useful for creating an additive system to reduce wear and friction for lubricating oil based on modified graphene and modified silver nanomaterials. ADVANTAGE - The method utilizes additive system: has good stability, compatible with commercial lubricating oil products; and increases lubricating efficiency of commercial oils when mixed in accordance with the recommended ratio for use, reduces wear, metal friction, reduce emissions, and reduce fuel consumption and prolong the number of kilometers that need to change the vehicle's oil.
