Lubricant Viscosities

Usage:

928G 6XR

The proper oil viscosity grade is determined by the minimum outside temperature when the machine is started. The proper oil viscosity grade is also determined by the maximum outside temperature while the machine is operated. Use the column that is called "Min" on the table to determine the oil viscosity grade that is required for starting a cold machine and for operating a cold machine. Use the column that is called "Max" on the table to select the oil viscosity grade for operating the machine at the highest temperature that is anticipated. Use the oil that has the highest viscosity for the ambient temperature when you start the machine.

Machines that are continuously operated should use oils that have a higher viscosity in the final drives and differentials in order to maintain the highest possible oil film thickness. Consult your dealer if additional information is needed.

For BIO HYDO (HEES) oil, tank temperatures should not exceed 100°C (212°F). Do not use BIO HYDO (HEES) oil in hydraulic systems with clutches or brakes. Do not use BIO HYDO (HEES) oil in machine hydraulic systems with jacket water cooling such as large track-type tractors or off-highway trucks.
