Manufactured from solvent refined paraffinic and selected additives offering good chemical stability, high performance to neutralize combustion residues in engines, good filterability, anti-wear properties and excellent detergency. Detergents in marine oils provide excellent deposit control for the high temperature zone of the engine, including piston under crowns and ring belt areas. Dispersants provide similar protection to valve decks, air ports, air blowers, air boxes, oil filters and oil coolers. these oils retain high TBN number during application, even when heavy fuels are being used. They provide excellent protection against wear and corrosion of engine parts.
