Servo MARINE 304 is an anti-wear, temperature-resistant and highly immiscible marine engine oil. This oil is manufactured specially for high speed engines and state-of-the-art rated pressure charged, medium-speed, trunk piston diesel engines which are inner combustion engines where a gudgeon pin links the connecting rod directly to the piston. These engines burn high viscosity residual fuel having over 2% sulphur content. The oil is extensively used in applications like marine propulsion and land-based diesel generators. The flash point of this oil, calculated by the Cleveland Open Cup (COC) procedure, is 230 deg C. The COC procedure determines the temperature at which the oil vapor catches fire when a flame is passed above the oil surface.
