The literature I have for my 91WL says straight 40 weight oil for the DD.

I'm also changing oil tomorrow. I've been using 15-40 Rotello. Please advise.

Detroits have no glow plugs and "off the shelf" no starting assist.
They are ENTIRELY dependant on engine compression to start. They
also require (not recommend, REQUIRE) straight weight strength required
by the injector followers - you WILL destroy cams
if you run a 15W40 in them,
