Superior shear stability produces stay-in-grade synthetic ester containing multigrade engine oils. Provides a high degree of anti-wear performance for stressed components. Provides enhanced high temperature deposit control resulting in a cleaner engine and thus promoting longer engine life and performance retention. Suitable for gearboxes and transmissions where engine oil technology is specified providing good pitting protection. Balanced frictional properties give precise clutch control/ operation. Also provides good corrosion protection, better oxidation/ nitration resistance and lower volatility than conventional products.
