I used to run it in my Cummins, not my PSD. It has a API CJ-4 cert so it will work fine in a PSD. Where are you located? How cold does it get in the winter?
I ran 15w40, usually delo or delvac depending on which was on sale, year round in Mass for 5000-7500 miles. If you live in Canada then a 10w30 or 5w40 might be a better idea.
The 10w30 version of the JD oil seems to be treating this guy well..
