Is Gear Oil the Same as Transmission Oil?
1 Answers
Gear oil and transmission oil are essentially the same, but they are used in different locations, hence the difference in names. Gear oil is generally used in gear transmission mechanisms such as automobile steering gears, transmissions, and drive axles. Transmission oil is a lubricant that keeps the vehicle's transmission clean, ensuring its proper operation and extending the lifespan of the transmission components. Below is some relevant information about gear oil: 1. According to the standards of the American Petroleum Institute (API), vehicle gear oils are classified into quality grades such as GL-1, GL-2, GL-3, GL-4, and GL-5, with corresponding quality grade labels on the packaging. 2. The higher the number after "GL," the higher the grade, meaning it can meet the requirements of gears operating under more demanding conditions.
