Transmission oil RENA Synchro Ultra 70W-90
Transmission oil RENA Synchro Ultra 70W-90
Synthetic 70W-90 oil for uninterrupted transmission operation. Ensures ease of gear shifting and protects bearings.
Temperature fluctuations create high loads on manual transmissions, impairing the smoothness of their operation. RENA Synchro Ultra 70W-90 is an innovative synthetic transmission oil that ensures stable ease of gear shifting in any weather. Its strong polymer structure completely prevents wear of bearings and gear teeth, reducing mechanical friction losses. The product maintains operational reliability at extremely low temperatures. Contact our specialist to discuss supply details and calculate specifications.
100% synthetic oil of 70W-90 viscosity class. Kinematic viscosity 16.0 mm²/s at 100°C. Pour point -55°C guarantees excellent start. Tribological weld load of 3280 N confirms shear stability. Meets API GL-4.
