Abstract (en)

[origin: WO2013087889A1] The present invention relates to a lubricating composition including one or more base oils, at least one dimercaptothiadiazole derivative, at least one ethylene and alphaolefin copolymer, and at least one amine thiophosphate. Said composition can be used for lubricating transmissions, such as gearboxes and axles, preferably the manual gearboxes of motor vehicles, and enables a reduction in the fuel consumption of vehicles, particularly of motor vehicles, due to the combination of the ethylene and alphaolefin copolymer, dimercaptothiadiazole derivative, and amine thiophosphate, which decreases the coefficient of friction of the lubricating composition.
