Description

Mobilube HD 85W-140 is a hypoid gear oil from the Mobilube range for axles and final drives in trucks, commercial vehicles and off-highway machinery. It is designed for gears working under extreme tooth pressure and shock loads.

The oil is rated API GL-5. The data sheet lists no equipment-maker approvals.

Typical figures: viscosity 27.5 mm²/s at 100 °C, viscosity index 97; after the 20-hour KRL shear stability test the viscosity is 27 mm²/s.

Application

Axles and final drives in trucks, commercial vehicles and off-highway machinery operating under extreme tooth pressure and shock loads.

Worth knowing

This oil’s specification list is a single line, API GL-5, and that is what separates the two Mobil 85W-140 cans in the catalogue. Mobilube HD Plus 85W-140, in the same SAE grade, adds API MT-1 and the Mack GO-J, SAE J2360 and Volvo 97321 approvals, so HD does not satisfy documentation that calls for one of those codes. The article on what makes SAE J2360 broader than GL-5 shows where that requirement for truck and bus axles comes from.

Mobilube HD-N 80W-140 also lists only GL-5, but its SAE grade is different: SAE J306 sets the 150,000 mPa·s limit at -26 °C for 80W and at -12 °C for 85W. The data-sheet figures differ too: 25.3 mm²/s against 27.5 mm²/s at 100 °C, viscosity index 125 against 97. A matching API class does not make it a substitute where 85W-140 is specified.
