Technosynthese lubricant mechanical transmission. This product is specially designed to fit mechanical transmission, synchronized or not synchronized 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. This Extreme pressure lubricant offers an efficient anti-wear protection reinforced with synthetic base stocks for a better resistance at high temperature and longer life time. This product has a high power of lubrication and decreases friction and wear, it has also anti-corrosion and anti-foam properties. This viscosity grade (SAE 80) at hot temperature reduces gearbox drag and fuel consumption. Its high fluidity at low temperature allow easier gear shifting when the mechanical parts are cold. Less effort is then required on the gear lever to shift the gears. Suitable for any type of seal and yellow material used in gearboxes design requiring API GL-4 / GL-5 and MIL-L-2105D standards.
