Transmission oil RENA Synchro Ultra 75W-90
Transmission oil RENA Synchro Ultra 75W-90
Universal synthetic 75W-90 transmission oil for reliable manual transmission protection. Ensures smooth synchronizer operation and reduces mechanical losses.
Temperature fluctuations create high loads on manual transmissions, impairing their smooth operation and accelerating part wear. RENA Synchro Ultra 75W-90 is an innovative synthetic transmission oil that ensures stable ease of gear shifting in any weather. Its strong polymer structure prevents wear of bearings and gear teeth, reducing friction losses. The product maintains operational reliability at extremely low temperatures. Contact our specialist to discuss supply details and calculate specifications.
Fully synthetic transmission oil. Kinematic viscosity at 100°C is 16.0 mm²/s, viscosity index — 110. Pour point reaches -40°C. The product is characterized by a weld load of 3280 N. Meets API GL-4 classification.
