Manufacturer's description

Mobilgard 300 C is a premium quality system oil specially formulated to provide superior engine cleanliness, better wear protection and longer oil life compared with conventional system oils, designed for two-stroke, crosshead marine diesel engines operating under severe conditions. It has sufficient alkalinity to protect against strong acids from the combustion of fuel sulphur, plus enhanced load-carrying ability to reduce wear in heavily loaded bearings and gears. It is recommended primarily as system oil in late model, high-output crosshead diesel engines, especially those using system oil for piston cooling, where it prevents or reduces deposit formation in piston cooling spaces, maintains piston cooling efficiency, and reduces piston top burning and crown cracking. Its good rust prevention and water separation characteristics also make it well suited to older crosshead engines with water-cooled pistons where crankcase deposits can be a problem. Formulated from high quality paraffinic base oils with excellent thermal stability and oxidation resistance, plus proprietary detergent and anti-wear additive systems, Mobilgard 300 C delivers enhanced crankcase cleanliness and excellent protection for heavily-loaded engine parts, along with good rust protection and excellent water separation.

Applications

• Mobilgard 300 C is recommended primarily as system oil in late-model, high-output, crosshead diesel engines, especially those using the system oil for piston cooling.
• It prevents or reduces deposit formation in the piston-cooling spaces, maintaining piston-cooling efficiency and reducing the incidence of piston top burning and piston crown cracking.
• It also prevents or reduces crankcase deposits and provides outstanding protection for heavily loaded bearings and gears.
• Good rust-prevention and water-separation characteristics make Mobilgard 300 C an excellent system oil in older-design crosshead diesel engines with water-cooled pistons, where crankcase deposits can be a problem with lower-quality system oils.

Performance & benefits

• The high-quality paraffinic base oils used in Mobilgard 300 C have excellent thermal stability and oxidation resistance.
• The formulation includes proprietary detergent and anti-wear additive systems to deliver enhanced crankcase cleanliness, along with excellent protection for highly loaded engine parts.
• Mobilgard 300 C also provides good rust protection in case of water contamination, and excellent water-separation characteristics.
• Enhanced detergency and improved thermal and oxidation stability: better piston-cooling efficiency and cleaner crankcases and circulation tanks.
