We know that lower viscosity oils offer better fuel mileage, and as a cost, less protection. Both to varying degrees and possibly at insignificant levels where an xw20 vs xw30 is concerned.
But since the march towards even lower viscosity is the industry trend, will the chemistry of these oils ever match the physical properties of the thicker oils where wear is considered? Are we there yet? Is it even possible? Has reliance on antiwear tech reached that point?
