Yes, it matters to the engine. Weight--or viscosity--requirement for a particular engine doesn't change with new oil technology, assuming one remains with the single weight oils. I don't think it wise to use a heavier than specified weight, especially in the winter, or a lighter than specified in the summer. But the new additives are shown to have an anti-corrosion and wear benefit.
