Feature and Potential Benefits
Mobilgard 300 is formulated from high quality paraffinic base oils that have excellent thermal stability and oxidation resistance. These base oil characteristics are augmented with a balanced additive system that includes special high temperature oxidation inhibitors, alkaline detergents, a load carrying component and defoamant. The formulation has maximum antiwear properties, good rust protection in the presence of salt water, and excellent water separation characteristics.
When used as recommended in crosshead type diesel engines, Mobilgard 300 system oil offers the following features and potential benefits:
| Features | Advantages and potential benefits |
|---|---|
| Improved thermal and oxidation stability | Reduced deposits in piston cooling spaces and crankcase, Better piston cooling efficiency |
| Enhanced detergency | Cleaner crankcases and circulation tanks |
| Excellent rust and corrosion properties | Longer bearing life, Protects critical bearing surfaces |
| Good water tolerance and separation capability | Effective lubrication in the presence of water, Longer oil life due to efficient water separation |
Applications
Mobilgard 300 is recommended primarily for use as system oil in late model, high-output, crosshead diesel engines, especially those engines employing the system oil for piston cooling. It will prevent or reduce deposit formation in the piston cooling spaces, thus maintaining piston cooling efficiency and reducing the incidence of piston top burning and piston crown cracking. It will also prevent or reduce crankcase deposits and will provide outstanding protection for heavily loaded bearings. Its reserve alkalinity allows for the burning of high sulphur fuel. Good rust prevention and water separation characteristics make Mobilgard 300 an excellent system oil in older design crosshead diesel engines which have water-cooled pistons and where crankcase deposits can be a problem with lower-quality system oils.
