Gear oil is a lubricant made specifically for transmissions, transfer cases, and differentials in automobiles, trucks, and other machinery. Gear oil helps your transmission run smoothly and more importantly, it helps protect critical internal components in your car’s gear systems from wear and heat damage. Transmission oil 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. Supergen’s unparalleled gear and transmission oil provide wear-reducing and extreme pressure protection.
