What is Gear Oil?
The vehicles we use every day, such as cars, trucks, and motorcycles, are complicated pieces of machinery, requiring proper maintenance and care. One product that is essential for the normal operation of these vehicles is gear oil. Gear oil is a lubricating motor oil made specifically for transmissions, differentials, and transfer cases in cars, trucks, and some industrial machinery. It has a high viscosity, or thickness, to ensure maximum protection of essential moving parts. Gear oil is similar in some ways to the motor oil used for engine lubrication, but has many different properties in order to cope with the different demands that are placed on it. Motor oil, for example, needs to be able to take a great degree of heating without breaking down, since it lubricates the parts in an engine that are directly adjacent to where the combustion takes place. Gear oil, however, does not reach the temperatures of engine oil. In contrast, it is associated with parts that move somewhat slower
