Techron MG 15W-40 Engine Oil API CI4+ CI-4/SM has anti-wear protection, that significantly increases fuel economy, minimizes engine wear, and lowers engine-operating temperatures. Detergents minimize deposits and neutralize corrosive by- products of combustion by providing the extra reserve alkalinity (TBN) to prevent rust and corrosion even when fuels containing high sulfur levels are in use. Shear- stable viscosity improving polymers impart improved viscometric characteristics for optimum performance and fuel economy during both cold stars and high operating temperatures in any climate. Antifoam agents assure proper lubrication to all engine parts. Powerful antioxidants and dispersants prolong oil life and extend drain intervals
