Description
Mobilgard™ ADL Series oils have been designed for high Brake Mean Effective Pressure (BMEP) medium- and high-speed diesel engines operating on distillate fuels.
Mobilgard™ ADL 40 oils each have a balanced formulation which combats lacquer formation and deposits in severe service applications. Superior load carrying properties help to minimise piston ring and liner wear, and also make the lubricants suitable for marine gearing applications.
Potential benefits of using Mobilgard ADL Series lubricants include helping:
• Extend component and critical wear surface life
• Improve overall engine cleanliness
• Reduce oil consumption
• Increase time between engine overhauls
Features and Benefits
Mobilgard ADL Series oils have demonstrated superior performance in the latest model diesel engines, including engines of MAN Energy Solutions Augsburg, Caterpillar (3600 and C280 Series), Deutz, and Wärtsilä. In extensive field testing on these engines, Mobilgard ADL Series oils corrected many problems normally associated with severe service engines operating on lower quality fuels. Results included dramatically reduced oil consumption, significantly reduced liner lacquering and extended periods between overhauls. These advanced diesel lubricants possess excellent water separation, rust and corrosion resistance properties.
Key features and potential benefits include:
| Features | Advantages and Potential Benefits |
| Increased thermal and oxidation stability | Improved engine cleanliness, reduced liner lacquering, reduced top deck sludge, reduced piston ring groove deposits and bore polishing |
| Superior wear protection | Extends the life of critical wear surfaces |
| Enhanced detergency/dispersancy capability | Reduced deposits especially in the ring belt area which leads to extended cylinder overhauls and reduced oil consumption |
| Stay-in-grade shear stability | Reduced oil consumption and improved bearing protection |
| High TBN levels | Prevents corrosive wear due to higher sulphur fuels |
| Broad range of engine applications | One severe service engine lubricant for all shipboard applications |
Applications
Mobilgard ADL Series lubricants are intended for use in high BMEP engines and in severe duty engine applications where the nature of the fuel and service requires a greater level of detergency/dispersancy and liner lacquer control than is offered by most diesel engine lubricants.
