Servo MARINE 204 is a high grade lubricant for high-speed and medium-speed marine engines with application in land-based diesel generators and marine propulsion. It has improved TBN retention, dispersion and good anti-wear safety which are requisites of an efficient marine lubricant. Moreover, it protects from sticky and corrosive wear when exposed to heat and detaches from water with ease. With a kinematic viscosity of 14.2–15.5 (at 100°C) and viscosity index of 90, it is utilized in highly rated medium-speed turbo-charged piston diesel engines that combust sulphur amounting to 2% or residual fuel or marine diesel oil.
