High-performance monograde diesel engine oil.
Mobil Delvac Legend 1330, 1340, and 1350 are high-performance monograde diesel engine oils formulated with advanced base technologies and balanced additives. These products are designed to deliver optimal performance to intercooled, turbocharged engines operating under demanding on-road and off-road conditions. Mobil Delvac Legend 1300 monograde is selected for the recommended operating conditions for monograde lubricants.
These products are fully compatible with Mobil Delvac 1330/1340/1350 and are interchangeable.
Key features and benefits
Designing smaller engines reduces lubricant consumption, resulting in the need for frequent oil changes to compensate.
Less additive is used up. The higher position of the upper piston ring brings the lubricating oil film closer to operating temperature.
Increased fuel combustion results in higher thermal stress on the lubricant, leading to increased fuel injector pressure and…
Delaying the engine’s timing improves fuel combustion efficiency, but it also increases the temperature and stress on engine components.
And it increases soot buildup in lubricants under heavy use. Mobil Delvac Legend 1640 is designed to deliver superior performance.
