If you are using it in the winter I'd go synthetic 5-30. Apparently it flows a lot better in the cold than conventional.

But since you've already changed it maybe plug it in first before starting in the cold. I am using the Boss Oil cam oil in the truck now which is a conventional oil with more zinc or whatever in it. I try plugging it in first for an hour or two before starting in the cold. It makes quite a difference. Once all my conventional oil is used up I think I'll go synthetic in everything, truck and Rambler included.
