Everything was great, with the exception of a mention of a small amount of soot in the sample. Used Mopar oil filter, changed to Baldwin. Just wonder what they mean about the soot in the sample.UpdateI know there is always soot present in the oil on a diesel, hince the coal black color of the oil. So......? Heres the report, what say you?[ATTACH]4282[/ATTACH]

Soot it exactly what you think it is!!! It's the stuff that coats the inside of your tailpipe. And some of the stuff is gonna get past your pistons rings no matter.IIRC, that's the "insolubles" part of your analysis!! Based on this analysis, keep on driving like you are............ain't no problems with this analysis at all!!!:2cents:Do you run a "bypass oil filter"?????

Yea, I know. Just wondered why the tech mentioned it. Refilled with Castrol again. It was on sale so I snatched up two cases (6gals). Bought Premium blue to replace it when it comes out.

Do you idle for long periods?

Do you idle for long periods?

No, but short trips 4 days a week. That's why there's only 6000 miles on the oil.

That soot level is nothing to worry about. At 8K miles mine is about 0.6% on a good sample, and that's with a bypass.Of course my motor seems to put more soot into the oil than most, but that's life sometimes.
