Planning an EGR Delete? Check Your Oil System First
Installing a SPELAB 6.7 Powerstroke EGR delete kit helps reduce soot—but only if your oil system is healthy. A failing oil cooler or pump can undermine performance gains.
Tip: Many owners upgrade the oil cooler and gaskets during EGR delete installation for added protection.
EGR System & Long-Term Oil Health
The EGR (Exhaust Gas Recirculation) system in your 6.7 Powerstroke is designed to reduce NOx emissions by rerouting a portion of exhaust gases back into the intake. While effective for emissions control, this system introduces a range of performance and maintenance drawbacks—especially when it comes to oil cleanliness and engine longevity.
If you're driving a Ford F-250, F-350, or F-450 and you’re serious about performance or reliability, understanding how the EGR system affects your oil—and what you can do about it—is essential.
How the EGR System Harms Oil Health
-
Exhaust gases carry soot, ash, and unburnt fuel particles
-
These particulates re-enter the intake and mix with oil mist from the crankcase
-
The result? A thick sludge that clogs intake runners, dirties your oil faster, and reduces fuel efficiency
-
Dirty oil = shorter oil change intervals, poor turbo lubrication, increased wear on lifters, cams, and injectors
This is one reason why many diesel owners choose to delete the EGR system—especially if they want their oil to last longer and run cleaner.
