I use Valvoline "not street legal" oil, might be over kill but better to be safe than sorry.
My motor been rebuilt 6 years old and like 30,000 miles on it. When a swap heads last month I looked at the cam-did not remove it,just looking at it, seemed it look fine. All lobes seem to look the same.
Amazon sells it but they get sold out now and then.
