|
General features
Vehicle gear mineral oil with very good lubricating and anticorrosive properties, high resistance to oxidation and high ability to transfer loads.
Application
It is intended to lubricate gears of vehicles, in particular gearboxes and final drives of cars, trucks and earth works machines operating in difficult conditions i.e.:
· high speed and low torque,
· low speed and high torque,
· and for those machines and devices, manufacturer of which recommends API GL-4 gear oil.
