Eni Rotra MP/S 80W-90
EP oil for limited-slip differentials and oil-immersed brakes
SAE 80W-90
Mobil Delvac Modern Axle Oil 80W-90 Limited Slip is an extra high performance automotive gear lubricant formulated from select base oils and an advanced additive system specifically for limited-slip differentials. It is recommended by ExxonMobil for applications requiring API GL-5 performance, such as heavy-duty differentials, axles and final drives where extreme pressures and shock loading are expected. It is recommended for limited-slip differentials, axles and final drives in passenger cars, on-highway light and heavy-duty trucks, buses and vans, off-highway construction, quarrying and agricultural equipment, and other industrial and automotive gear applications under high speed/shock load, high speed/low torque or low speed/high torque conditions; it is suited to initial fill, top-up and refill wherever SAE 80W-90 limited-slip gear lubricants are recommended, though not for transmissions or transaxles calling for engine oil or ATF. Key benefits include excellent frictional properties for effective limited-slip performance, good thermal stability and resistance to high-temperature oxidation, protection against low-speed/high-torque wear and high-speed scoring, excellent rust and corrosion protection, effective low-temperature lubrication, good resistance to foaming, and compatibility with typical automotive seals and gaskets. The oil meets or exceeds API GL-5 and carries TE-ML 21N and TE-ML 05N approvals.
