What is the absolute best hardware fix to stop raw fuel from diluting the engine oil on a 2008-2010 6.4L Ford diesel?

Every 2008-2010 6.4L Powerstroke owner lives in fear of "making oil." The factory active regeneration cycle dumps raw diesel into the cylinders on the exhaust stroke, washing past the rings and severely diluting your engine oil—the ultimate recipe for spun bearings and cracked pistons. We all know that dropping the factory emissions equipment and re-routing the setup is the ultimate hardware fix to stop this wash-out, but what are your real-world oil analysis results?

Did removing that factory restriction completely stabilize your oil levels, or did you still need to change your oil viscosity or service intervals?

To answer your question about viscosity and intervals: Yes, removing the DPF restriction completely stops the 'making oil' crisis because it completely deletes the post-injection command from the ECM. However, do not fall into the trap of thinking you can now run 10,000-mile oil changes like a standard semi-truck.The 6.4L Powerstroke is still incredibly hard on engine oil due to the massive shearing forces from the high-pressure oil pump and the tight tolerances on the lifters. My Blackstone reports showed that even with 0% fuel dilution, the oil still breaks down chemically around the 5,000 to 6,000-mile mark. I stick strictly to a High-Quality Conventional or Synthetic 15W-40 and still dump it every 5,000 miles. I didn't change my interval to save money on oil changes; I did the hardware fix to save my rocker arms and crankshaft from spinning a bearing.
