Anyone used this yet (15W40 flavor) in their PSD?
I bought a case at Rural King on sale very cheap and figured I'd give it a go in my 05 PSD with the 6.0h. I have been using Rotella T4 10W30 and the truck seemed to like it especially when I lived in WV and had to start it during the winter but now that I'm in Central Florida and the wife hauls the horses pretty often I figured the 15W40 would offer a little extra viscosity during the hot months and we all know how bad the HEUI system beats up oil anyway.
I mean, its good enough to be the "only one" for Cummins so it has to be good, right!
