System oil for marine crosshead diesel engines with sufficient alkalinity to neutralise any strong acids, which may enter the crankcase from the combustion of fuel. It has enhanced load-carrying ability in order to reduce wear in heavilyloaded bearings. Recommended for use as a system oil in high-output, crosshead diesel engines, as well as a piston cooling medium. It can be used in small trunk piston engines whose fuel contains less than 0.5% in sulphur.
