Although some people will not agree, all non-synthetic motor oil is about the same. As long as it has the correct API service code or higher ie: SC,SD,SF etc. for your engine oil change interval is the most important thing IMHO. As for the lube for the cam, the S/M (1985)says use motor oil. I personally would buy some engine assembly lube, they should be able to get it for you at the auto shop. It's cheap insurance. HTH
