From what I've seen the odds are looking at it being three lines but I don't want to give bad/wrong info. I have nothing to in my resources for Olds motors in the mid '80's to break down what would state which would be needed. Sorry for not being able give usable info.
it's calls for 10w30 conventional are Sythetic i heard run conventional in them older cars but everybody has a there own judgement
Maybe a hi-mileage oil would be a good suggestion. As for conventional oils made today they are not like what was out there in the '80's. They don't have the needed zinc in them so a zinc additive would be needed regardless unless it's something like Valvoline's racing oil line or vintage car blends.
