Forest, I use Delo 400 LE 15W40 in both engines. The series 60 is 38 qts according to the Detroit book. I don't know about gen. I feel any good brand is fine. I used Shell in my other MH. The reason I'm using Delo is I understand that is what MHT used when they changed the oil when I bought the coach last year.
