Transmission oil RENA Synchro Ultra 75W-140


Transmission oil RENA Synchro Ultra 75W-140
Specialized thick synthetic 75W-140 oil for manual transmissions with maximum loads. Prevents wear at extreme temperatures.
Operating vehicles in extreme competition conditions or heavy off-road creates critical contact loads on gear drives. RENA Synchro Ultra 75W-140 is a thick synthetic oil that forms a super-strong film on gears, protecting them from destruction and scuffing at extreme temperatures. The product guarantees stable manual transmission operation even under boundary friction conditions and excellently absorbs shock loads. For detailed consultation and placing an order, contact our manager.
High-viscosity 100% synthetic oil of 75W-140 class. Kinematic viscosity 28.2 mm²/s at 100°C. Pour point -40°C. Weld load of 3280 N indicates polymer film reliability. Meets API GL-4 requirements.
