Once DC's oil consumption test is over, 5W40 goes back in. If that doesn't stop the oiling, will try the 15W40. This is the only vehicle I've owned (gas or diesel) where the OEM was this anal about oil standards (and got it wrong on the standard). Even my dealer is questioning the CF vs. CI-4.

I have noticed that while driving at night with lighting behind me, that when I
accelerate hard that a fair amount of particulate matter is exhausted.
Is that normal, or could that be evidence of oiling past the turbo seals.
I really can't see it in the daytime.

That is a real good indication. If you inhale motor oil vapors you will get either soot (if it burns) or oily exhaust which in theory will get burned in the catalyst which will also make soot. Keep in mind that VGT blades rotate (change pitch) and are subject to oil/sludge coking causing them to stick/malfunction.

The best way to tell is you are getting oil through the seals:
1). Eliminate the CCV as a cause (install a Provent or just open vent).
2). Thoroughly clean your CAC hoses to the original bright red condition. Don't forget to clean the rubber boot from the airbox to the turbo. A little biodiesel and a dish brush cut right through the oil without damaging the silicone lined hoses. Ether works well too.
3). Reassemble and drive the vehicle. Over time, monitor the CAC hoses, especially the turbo to the intercooler hose for fresh oiling. The intercooler to engine hose will continue to foul until the all the oil is purged from the intercooler.

I have mine down to a small amount in the first 4 inches of the CAC hose past the turbo. If you do find oiling, need to find the reason (filter constriction, light weight oil, defective turbo, etc..). Finally, forget about arguning the point with DC. They will tell you it's from the CCV and that it's normal regardless of the sorce or damage it will cause over time.

Thanks for the info. FYI the only 0w40 oil run through my CRD was what came
from the factory. I've mostly run 5w40.5w30 and15w40 in descending order.
Also since no one answered my thread, have you seen a need to adjust your emergency brake? I have to push mine
almost all the way to the floor to engage.

Where's your smiley face? I don't think you were talking about wheels.

OK, now that's funny. No, talking about some other kind of treads. Anybody who says the Libby is too small for them I say BS! If I can get shoehorned in there, so can they.
