Castrol Alpha SP Series Introduction Alpha SP series deployed by parathion compounds made with extreme pressure and anti-wear properties. This series of gear oil showed good thermal stability and oxidation resistance, also has anti-emulsifying, low foaming tendency, etc., while providing excellent rust and corrosion of metal surfaces. Performance Alpha S Series gear oil through the internationally recognized tests, including FZG, Timken TIMKEN OK value and four-ball test, and the results see "Technical Data."
