This certification ensures the oil contains the necessary detergent and dispersant packages to handle the soot-heavy environment of a diesel particulate filter (DPF). Conversely, the 15W-40 maintains a thicker film at high operating temperatures and heavy loads, making it the preferred choice for consistent towing in warmer climates or severe duty cycles.
6.7 Powerstroke Oil Additive Safety: Protecting Your Engine in a DPF Environment
The 5W-40 offers superior cold-flow characteristics, which is ideal for regions with harsh winters, allowing for faster lubrication during startup. The Critical Role of Oil in the 6.
Diesel engines generate significantly more soot and metallic particles than their gasoline counterparts. Over time, the oil breaks down, becoming acidic and sludge-like.
6.7 Powerstroke Oil Additive Safety and Performance Considerations
This specific engine, found in numerous Ford trucks and vans, places immense stress on its internals, and the correct lubrication is the primary defense against premature wear. However, if you are a daily hauler, frequently towing heavy trailers over mountain passes, the thermal stability and shear resistance of 15W-40 will better protect the engine under sustained stress.
