I agree, everything else looked really good. I normally run this set-up out to 10K miles without much thought. I just thought that I'd run an analysis on this batch of oil because of the injector failures looking primarily for excessive fuel. On a side note, I do use the Schaffers Diesel treat 2000 mixing 3 oz. with 26 gallons of fuel.

Just wondering why the combination of oil? 7k and 9k. Is the moly lube widely used ?

Well I got my latest report from Blackstone today. It read as follows:

Sample was run for 10,326 miles on Schaeffers 15W-40 w/ Mobil 1 303 filter.

AL 3
CR 1
FE 29
PB 7
CU 305!!!!!!
Moly 305
Tin 0
Nickel 0
Manganese 0
Silver 0
Titanium 0
Potassium 3
Boron 7
Silicon 8
Sodium 11
CA 1528
MG 860
Phosphorus 1137
Zinc 1554
Barium 0
SUS Viscosity @ 210F 84.3
cSt Viscosity @100C 16.59
Flashpoint 435F
Fuel <0.5%
Antifreeze % 0.0
Water % 0.0
Insoluble % 0.3
TBN 4.8

This was a lot of highway miles with light towing daily. What can possibly be causing this much copper consistantly in the 2 UOA's. I am about to go to Wal-Mart tomorrow and buy the Delo 400 for $8.50 p/gallon and call it a day. Anyone have any ideas on this. Possible impending premature turbo failure????

Also, note the viscosity climbed out of the 40W range. Could theoil be too thick for the turbo bearings possibly??? Just trying to get a handle on what could be happening here. Thanks.

This is a good read

"It seems to boil down to three things: zinc dialkyl dithiophosphate (ZDDP), heat and new engines. The principle elemental component of ZDDP is sulfur."

Ok, so I read the article you mentioned, which was very informative...thank you. It mentioned that the copper typically happens in new engines less than 1,500 hours. My engine has almost twice that. (2,800 hours) The last 2 UOA's have shown significant CU and FE compared to similar engines, uasgage, mileage, etc. The last batch was run primarily on the interstate at 70MPH and no heavy towing. (Less than 5-6,000 LBS)Always cool down after a long run and don't flog on it until properly warmed up. Any other ideas?

Well, I dumped the most recent batch of Schaeffers after my last UOA showed a lot of CU. I replaced it with the Delo 400 LE that's on sale at Wal-Mart for $8.50 p/Gallon. I plan on resampling at 3,000 miles and see where the CU levels are at. The Schaeffers was in for a little over 1,000 miles. So, I would think that I should get a somewhat better idea on what's going on here. Could the high viscosity on the last UOA be too thick for the turbo bearings? I'm just taking a shot in the dark here.

I'm doubting the Schaeffer's is the problem, I'll be interested to see the results of the Delo though!

I doubt it also, but I wanted to make a switch and do a process of elimination. If the oil isn't the problem, then would that mean the oil cooler or something else that has a copper makeup be on its way out? Maybe someone here knows what may be the cause of the copper.

I'd wait two OCI's before drawing any conclusions with the new oil. It is possible the Schaeffers oil isn't the best choice for your engine hide, but a 3000 mile OCI isn't going to give an accurate answer. Going by what I've learned here it is best to run an oil 2 OCI's before jumping to any conclusions. If your 3K sample shows an improvement in Cu that would be a good sign, if it doesn't then I would suggest re-sampling after 2 OCI's. JMO

I totally agree with you there. Switch oils and make sure it's not the oil :)

When my CU jumped from 173 to 305, that tells me that something is definatly not right somewhere whether it's the oil or something else. Does anyone know or have any experience with the possible mechanical problems that could be occuring here???

Tubo bearings may be a good call. Have you researched and/or posted a question on any of the vehicle/manufacturer forums?

Not as of this moment I haven't. Probably wouldn't be a bad idea though. Thanks for the advice on the manufactuer's sites.
