Amsoil has just introduced a 5W-30 synthetic oil specifically for European cars. Intended to lubricate modern Euro gasoline- and diesel-powered vehicles, the oil is formulated to stay in grade throughout the extended drain intervals recommended by manufacturers. It's engineering to promote optimum emissions system performance and life, which will help reduce maintenance costs. Friction modifiers and the lighter 5W-30 viscosity maximize fuel economy as well. Amsoil recommends its new oil for VW, Mercedes, BMW and Porsche.
