Re: Parafin based outboard oil
As member Ben Walker has stated, most engine lubricants come from paraffinic-based crude oils. Really your choice in oil is either conventional base (paraffinic), a blended or semi-synthetic base (both paraffinic and PAO), or fully synthetic (PAO). <br /><br />Paraffinic crude is often wrongfully associated with waxy oils. But during the oil refining process dewaxing is performed and the maximum amount of wax is removed. Believe it or not, a small amount of paraffin is actually beneficial in terms of helping the oil to resist changes in viscosity with temperature, increasing its lubricating properties, and increasing oxidation resistance. <br /><br />These days, paraffinic based crude oils are highly refined into motor oils that will exceed your engine manufacturer's specification.
