Subject: Re: Suitable Engine Oil
Here in North America the removal of zinc from most oils is a cause for concern as that is what protects cam lobes and lifters from excessive wear. Fortunately, for now over here we have available Shell Rotella 15W 40 oil formulated with highly stressed diesels in mind and possessing the needed additives for our elderly designs. This subject has been widely discussed on many other forums and not being a petroleum engineer can not comment further . I do believe the philosophy of using any cheap oil is incorrect.
