so according to ford it is normal for this engine to make its own oil?

Unfortunately it is. All the EPA crap does this to our trucks. Hurts the motor and gives lousy mileage. DPF and CAT delete and tuner are the only way to fix it. A mild tune will not hurt the truck and deleting will only make it last longer.

If the tuner has shut off the regen cycle then eventually you will plug things up. Not sure about your tuner but my Spartan has different tunes that will run with the regen cycle not hurting the cat/dpf. If you just run the tuner and a dpf delete pipe then same thing, eventually you will plug the cat.

Always been adding 15qt and it reads slightly above the stick. All this talk makes me want to measure the amount I drain out every time.

I found this


Injector O-Rings
A TSB has been published on the Ford 6.4L diesel injectors concerning the premature wear of the injector O-rings. The O-rings prevent diesel fuel from leaking out of the fuel system and into the crankcase. This leaking into the crankcase creates oil levels to rise and damages the engine.

This could be the same problem the 6.7 are having.
