• High viscosity index, which helps provide effective lubrication over a wide range of temperatures
• Excellent shear stability, which promotes effective gear protection
• Good oxidation stability, which helps against the formation of sludge
and other harmful deposits
• Improved low-temperature performance (versus a WB101 fluid)
Applications
Suitable for use in applications requiring Volvo Transmission Oil 97304, WB102.
