Addisol offers a range of automotive gear oil additives, designed to meet extreme pressure, thermal stability and other requirements of the industry's most severe automotive gear oil specifications. Gear Oil Gear oil additives are used to formulate high load-carrying, low wear, energy-saving lubricants for automotive and industrial gear and bearing applications. It has excellent oxidative and thermal stability. It works effectively to prevent the gear surface from abrasion, wear, corrosion and rust and therefore extending its useful life. The main advantage of these gear oils is their reliability under severe operating conditions. ATF Automatic transmission fluid (ATF) is the fluid used in vehicles with self shifting or automatic transmissions. It is typically coloured red or green to distinguish it from motor oil and other fluids in the vehicle. The fluid is optimized for the special requirements of a transmission, such as valve operation, brake band friction and the torque converter as well as gear lubrication. ATF is also used as a hydraulic fluid in some power assisted steering systems, as a lubricant in some 4WD transfer cases, and in some modern manual transmissions.
