1.5% fuel in oil

[BlueF350]

I just received my latest Blackstone report and my fuel is back to 1.5% after the 11B23 update. I had been at 1.5% forevever and then last fall my regens started to happen every 200 miles and my fuel in oil went to 4.5% then 5.5%. Now my regens are 575-775 miles apart and this last change went really well. Plus, the truck runs so much better with the 11B23 that I'm really enjoying it. I'll keep testing the oil every 5k miles hoping that we can stay the course on this.

With all this regen BS, it is good to stay on top of your oil reports. Mine went from 4.5 to >.5 when the DPF/DOC fell off while off roading...................

Do you guys have your oil tested just to see how your engine is doing as far as wear and tear? I remember reading a blackstone thread a long time ago that explains all the test results but I couldn't find it?

a Blackstone report is a good check on how the engine and oil are working so I do it every time.
