100% synthetic lubricant for all mechanical transmission of high performances and racing cars. For synchronized or not synchronized gearboxes, gearbox / differential, transfer gearboxes and hypoid differentials with limited slip system operating under shocks, heavy loads and low revolution speed or medium loads and high revolution speed. 0% shear loss: Unshearable oil film in extreme conditions. Very high lubricating power which decreases friction and wear. 90 grade at hot temperature to provide outstanding oil film resistance at hot temperature and / or to reduce transmission noise. Fluid at low temperature to allow comfortable gear shifting.
