Lubricating oil composition for use in all transmission systems

A lubricant composition for a full transmission system, comprising:

• (A) at least an ashless dispersant of 0.5-5.0 wt % based on the composition, being mono(polyisobutenyl) succinimide, or bis(polyisobutenyl) succinimide, or multi(polyisobutenyl) succinimide, boronated mono(polyisobutenyl) succinimide, or boronated bis(polyisobutenyl) succinimide, or boronated multi(polyisobutenyl) succinimide, or borophosphorated mono(polyisobutenyl) succinimide, or borophosphorated bis(polyisobutenyl) succinimide, or borophosphorated multi(polyisobutenyl) succinimide, or mixture from any combination thereof;
• (B) at least a friction modifier of 0.1-2.0 wt % based on the composition, being long-chain phosphate, or long-chain phosphite, or long-chain phosphonate, or long-chain fatty acid ester, or long-chain boronated fatty acid ester, or long-chain phosphate amine salt, or long-chain phosphite amine salt, or long-chain phosphonate amine salt, or mixture from any combination thereof;
• (C) at least a phosphorus-containing antiwear additive of 0.1-2.0 wt % based on the composition, being the mixture of thiophosphoric acid fatty amine formaldehyde condensate, thiophosphoric acid benzotriazole formaldehyde condensate, and thiophosphate and amine salt thereof;
• (D) at least an antirust additive of 0.01-1.0 wt. % based on the composition, being calcium alkylbenzene sulfonate, or alkyl calcium alkylbenzene sulfonate, or sulfurized alkyl phenate, or mixture from any combination thereof;
• (E) at least a sulfur-containing extreme-pressure additive of 3.0-6.0 wt % based on the composition, being sulfurized olefin, or sulfurized polyolefin, or alkyl polysulfide, or mixture from any combination thereof;
• (F) at least a metal deactivation additive of 0.01-1.0 wt % based on the composition, being thiadiazole disulfide, or alkylated thiadiazole dimer, or thiadiazole fatty amine formaldehyde condensate, or adduct of thiadiazole and long-chain olefin, or mixture from any combination thereof;
• (G) at least a viscosity index improver of 0.1-25 wt % based on the composition, being polymethacrylate, or polyisobutylene with a molecular weight of 800-2000, or mixture from any combination thereof;
• (H) at least a pour-point depressant of 0.1-2.0 wt % based on the composition, being polymethacrylate, or poly(α-olefin), or mixture from any combination thereof;
• and
• (I) at least a highly refined mineral oil with high viscosity index, or polyolefin synthetic oil, or ester synthetic oil, or mixture from any combination thereof, of 56.00-96.08 wt % based on the composition.
