Servo MARINE 53 is a high quality marine engine oil particularly developed to meet the criteria of high-speed engines and medium-speed trunk piston engines installed in DG sets and ships. These DG sets and ships run on residuals fuels which are the lowest-value products of petroleum distillation. The typical properties of this oil include proper viscosity, oxidation resistance, safety against abrasion and greater TBN retentivity to facilitate enhanced resistance to corrosion thus resulting in longer life-span of the oil. The Indian Oil Corporation Ltd. (IOCL) produces this oil at request.
