Yea, new diesels are coming with catalitic converters too now. I stopped using Rotella as well. Just add the ZDDPplus to good regular oil. There are a couple of "off-road" use oils that still have high levels of zinc in them, like the Brad Penn and a few others I can't remember right now. It's been discussed here several times, try searching for it going back a year or two.
