Recommended oil

#1
doing a heavy tuneup on a "new" '85 Southwind, chevy 454, 45K and am wondering what recommendations for oil weights there are out there - summer and winter. I used Mobile 1 synthetic in my other cars, various weights. Thanks in advance and for any other advice on maintenance peculiar to these engines. ThX

Re: Recommended oil

Mobile 1 should work. The diesels require a special weight diesel oil. however, the Chevy 454 should purrr on syntetic oil.
