Hey guys I was wondering which grade oil is recommended for a 89 Brougham w/ 5.0 (Olds 307 4bbl carb)? On the oil filler I see it says 5w30, but I called the Cadillac dealer and my service advisor said I could use 10w30?? Which is reccomended and which is best???
Also, to double check this car takes 5 quarts of oil right? (That's what my Chilton said).
Thanks guys.
