SINO S.O Marine Oil DF-HD is formulated with highly refined base oils and a balanced additive system to meet the demands of heavy duty marine diesel engines. It delivers good acid neutralisation, strong wear protection, and stable thermal performance for engines operating under long, continuous running conditions.

It helps maintain engine cleanliness by controlling deposits, supports reliable lubrication at elevated temperatures, and provides protection against frictional wear and corrosion. Recommended for crankcase lubrication of trunk piston engines running on low sulphur distillate fuels, it supports longer service life and dependable performance.
