Technosynthese® lubricant designed for all mechanical transmission, synchronised or not synchronised gearboxes, gearbox/differential and transfer gearboxes without limited slip system operating under shocks, heavy loads and low revolution speed or moderate loads and high revolution speed. Very high lubricating decreases friction and wear. SAE 80 grade at hot temperature reduces gearbox drag and fuel consumption. Fluid at low temperature to allow easier gear shifting when the gearbox is cold. Less effort required on the gear lever to shift the gears.
