Lubricant developed to meet the current demands of four-stroke diesel engines used in the marine sector, operating with current low-sulfur diesel fuels (less than 50 ppm) and not equipped with after-treatment systems. Formulated with highly refined base oils, which give it high resistance to oxidation and degradation, in addition to providing stable viscosity at high temperatures and low volatility, reducing lubricant consumption. Balance composition of detergent and dispersant additives, it eliminates deposits on valves and piston rings, preventing their buildup and preventing wear and oil leaks.
