I don't have the time to read for hours right now. Too busy at school right now.
I'm leaning toward keeping the newer suff and selling the older type.

The newer "low emissions" diesel oils still have a good bit of zinc, but imo, guys pay too much attention to zinc levels. Afaik, an oil made from a better base [better grade of crude] would not need as much zinc etc to be "good". There was some internet chatter some time ago about the fact that Brad Penn oil was not all that high in zinc. Afaik, they have since added more, perhaps just so people might think it's better now. Even if it really didn't need it.
Then again, I would not use the low zinc oils with the "starburst" symbol.
Although the foaming issue could be a valid concern, imo, if a diesel will live with it, it's pretty good lubricant. Fwiw, Ray Barton, the Hemi guy, told my buddy to use 15/40 diesel oil in his mopar race engine, which he does. Note - that was probably before the newer spec diesel oils existed though
And, if you dig around, you can read opinion that there IS such a thing as having too much zinc and maybe phosphorous too......
Sorry for the mud, Tom.
