MARINE LIFE 100 is a premium quality marine lubricant specifically developed for slow-speed crosshead and large trunk piston diesel engines used in marine propulsion systems. It is formulated using high-quality base oils and a highly alkaline additive system designed to provide outstanding protection under severe operating conditions.The very high alkalinity reserve (BN 100) effectively neutralizes strong acids generated from the combustion of high sulfur residual fuels, helping to protect cylinder liners and piston rings from corrosive wear. The oil provides excellent detergency and dispersancy, reducing piston deposits and maintaining engine cleanliness.
