Technosynthese® high Performance anti-emulsion gear oil specially formulated to lubricate outboard big engine high loaded propeller boxes. This product is specially developed for outboard big engine propeller boxes operating under shocks, heavy loads and low revolution speed, or moderate loads and high revolution speed. It is formulated with “Extreme Pressure” additive, anti corrosion and anti-foam properties for efficient anti-wear protection, better resistance at high temperature and extended life time. It is also reinforced with synthetic base stocks to increase oil film resistance even in the most extreme conditions. This produts offers a viscosity grade (SAE 90) at high temperature to provide outstanding oil film resistance at high temperature and high load, and to reduce transmission noise.
