Castrol 0W20 Magnetic Stop/Start Engine Oil is a premium quality lubrication fluid used in an extensive variety of vehicles/transmissions. It provides excellent thermal, oxidation, shear stability, and high resistance to foaming and corrosion. It resists deposit formation and provides for extended drain intervals. It provides superior low to high-temperature performance. It can be used year-round in all climates. Good frictional characteristics and wear protection help provide maximum cold temperature performance, excellent friction retention, and smooth shifting. High oxidation resistance helps with rust and corrosion as well as fluid change intervals. Meets requirements for foam protection and helps protect against metal-to-metal friction and wear within the transmission.
