Those numbers look pretty good. None of the wear metals are anywhere near being out of spec or excessive. The only thing that even remotely concerns me on that analysis is the viscosity. It's on the verge of being too low and down into the 30 weight range, however it still is a 40W, but just barely. Overall though, you have nothing to worry about on that analysis.

The Calcium, Zinc, and Phosphorus are all additives that are put into the oil, all to help reduce wear in the extreme pressure and high wear locations. I'm guessing this was the newer CJ spec oil, based on the low zinc and phos levels. The oil companies had to lower the content of those two in order for the oil to meet the new spec. That's why you'll see those numbers lower than the universal averages...since the average is from years of the older spec oils which had higher contents of those additives.

On a note about those additives, the long term effects of the reduction of them is not yet known, but it is widely believed among many that the effect is going to be an increase in engine wear. There's just not enough data out there yet to show whether it will or not.

I'll be curious to see the OUA's on engines as the CJ spec oil is used. The Zinc and Phos kind of 'plate up' on the engine's metal parts to help protect them, but once that plating is worn down, I don't know if there will be sufficient additives to continue to protect the engine, unless there is something else in the oil, such as Moly to make up for the loss of Zinc and Phos. Time will tell I guess.

Synthetic oils are just fine for use in a diesel engine and will not harm them in any way at all. I've been running a synthetic in my diesels for the past 6 years.
