Awesome information in this thread - looks like I will be giving the John Deer Plus 50 10W-30 a run in my "new to me" 6.0L.

Thanks Garack, I've been using Schaeffer's 7000 15W-40 syn blend in the 7.3L's with an occasional oil analysis. Been running it this way for almost 10 years. Now that I gave bought a 6.0L I'm trying to find the happy place between the oil sheering properties and cold start benefits. In the 15...

thanks for the link!

I hear ya.....I was hoping to find something about zinc levels, antimony or other wear and antioxidant requirements. So far just the standard - "it's improved" release.

My diesels are all pre 2007 so I'm curious how these new specifications are going to affect my non EGR Diesels.

Does anyone know the difference between CJ-4 and CJ-4 plus oil?

OK, I am a bit confused. What VOA was this for then?

I had the same thought. I thought CST Viscosity@100C was 12.5-16.29. Looked to me like this sample was just about center of mass.

I think it is the New T-6 5W-40. Thanks for posting the VOA. Interesting to see Rotella adding Moly to there additive package.

Nice UOA report.....

DieselTech, I'm not arguing with you and I could be wrong in this situation, but I have not seen many 7.3L UOA reports that have been related to copper core leaching. I have quite a few on the duramax and a cuople of CAT motors - showing copper in the 200-400 ppm range. Couldn't the copper be...

Ernest, keep in mind that the results on a UAO are not to be taken as exact measurements. You can easily see a 3-4 ppm difference in the results of the same oil sample run through the analysis twice. IIRC the test is reading the 4-7 micron range. I do not know why Molybdenum would show up on...

Originally Posted By: sdan27 Yeah, I think I'm going to stick with the Service Pro product. I really liked the way that the Schaeffer's grease looked so I'm still a little uncertain on that one but I think I'm going to stick with the Service Pro engine oil/hydraulic oils. Thanks to all for their...
