Preacherboy, in your case, if you are not idling your truck and it is still turning black,.. Then you still have something wrong with either your engine, or its programming. I have seen a lot of CM870 engines with clean oil.

The benefits of having perfectly clean oil in the engine all the time are huge. It is well known by now that a CM870/CM871 will yield about 40% less wear in most of its components when set this way.

The bottom of the engine is fine so I will be doing the top end this year. Hopefully we will find an issue with the head. I did the bubble test and found two bad injectors. I am going to see if that works and then look at programing. A reputable guy (who works with Unilevers and is on this board) did the tune so I dont think that is it.
