First, I agree with the change to Delo. Not that I am blaming Amsoil or Schaeffers or any other expensive oil, but the key is to get as close as possible to "normal" in a UOA, and for Blackstone that is dino oil and 6.5k mile samples.

Next, it's OK to use the dino oil as a flush agent. Nothing says you have to do several OCIs with dino at 6k miles each. Although somewhat of a waste fiscally, you can run three consequtive dino oil OCIs at 2k miles each, to expediate the flush process. Then, after those short flushes, run a "normal" 6.5k mile OCI and sample. Part of the concept is to allow the engine to normalize to the chemisty of the host oil, but part of the concept is also to flush out the previous oils. You can accomplish both with short OCIs. AFTER that, then do a "normal" OCI and sample.

Further, and I'm not sure about this, so take this with a grain of salt, but are the bearings in the Dmax ceramic? I had heard this from another source, but I am unable to confirm. This would change our view of the turbo issue, perhaps? I'm the first to admit that I don't know much about the VGT turbo in the Dmax (and I even drive one!).

I'm wondering why Schaeffers is recommending adding #132 to their engine oils. Is there already not enough Moly in them? How does excess Moly affect Cu and other yellow metals in the engine?

I was actually under the impression most manufacturers had moved over to ceramic turbo bearings...something I heard/read a while back.

#132 contains very little moly, check a VOA on it.

I was actually reading on the dieselplace forums about excessive CU on Amsoil samples. Some as high as 1,000 PPM!!!! It could very well be something in the High $$$ oils that gives the results that we're seeing. I also read that if the bearing are going out, then the tin and aluminum would also be high. As far as the type of bearings that are in the turbo, I will call my Chevy garage tomorrow and find out. It will be interesting to see what results the Delo will return on a UOA.

Is there a possibility that the #132 either has some copper in it or is causing some sort of reaction with the oil cooler? The viscosity has out of the 40 WT range on the high side. I was thinking that the 132 may've been the issue. But I guess the Delo UOA will tell the story whether or not the issue is lube or mechanical related. Any other ideas???

If they have an oil cooler like a Cummins, copper is typically from the leaching of the copper cooler. This is well documented in Cummins engines, and there is even a report from Cat regarding copper from cooler leaching.

The Duramax engines are well-known for oil cooler leaching until a certain point when they are new. This engine is well past new though as it has 68,000 miles and over 2,800 hours. It could very well be just the oil cooler leaching out, but I will see what the Delo UOA says this OCI. If it reads proportionally similar, then the oil isn't the issue. (I don't believe it is at this point, but I am going through the process of elimination.) I use Schaeffers in everything else on the truck, except the Allison. (Transynd). I am a firm believer in the Schaeffers product, but I also know that every product doesn't work in every vehicle for whatever reason.

Ok, the bearings in the turbo are ceramic. Blackstone seems to think that the oil cooler may have a crack developing based on both UOA's. Does anyone know if this would be likely? I haven't read anything about this being an issue anywhere.

A crack would show signs of antifreeze??

I had a spike in copper when I changed oils...different oils affect the cooler differently.

Yeah, possibly. They tthink that the crack might just be starting to form and that antifreeze would be a tell-tale sign of that if the crack gets big enough. The last 2 UOA's were the 5th and 6th fills with the Schaeffers, so there really wasn't a change in oil until just recently. I don't know at this point. The Delo UOA will point me in the correct direction hopefully.

Well I got my latest sample back from Blackstone today. This was the Delo 400 LE 15w/40: Miles on oil 5,624.

Antifreeze % 0.0
Water % 0.0
Insolubles % 0.3
TBN 5.9

DNewton has proven points regarding high dollar synthetic vs. Dino oil in the Duramax engines. This most recent UOA is another to back up what he's already said. Looks as though after this batch of Schaeffer's gets to 3K I'll run another UOA. If the copper returns, Delo will be the choice for this engine, and at a significant less cost to boot. Feed back is welcome as to why the Delo produced drastically lower wear metals.

Could it have something to do with the PAO in Schaeffer's? I have no idea just throwing it out there.

It could possibly be due to something with the #132 that was added to the first 2 batches of Schaffer's. I guess that sometimes more money doesn't always equal better results.
