Are gear oil and transmission oil the same?
1 Answers
Gear oil and transmission oil are the same. Transmission oil includes manual transmission oil and automatic transmission oil. Manual transmission oil is collectively referred to as gear oil, while automatic transmission oil has a higher grade and is also called drive oil. At the same time, ordinary gear oil cannot be used in automatic transmissions; automatic transmission oil must be used instead. Gear oil is mainly composed of petroleum lubricating base oil or synthetic lubricating oil, blended with extreme pressure anti-wear agents and oiliness agents to form an important lubricating oil. It is used in various gear transmission devices to prevent tooth surface wear, scratches, sintering, etc., thereby extending their service life and improving power transmission efficiency. Gear oil should have excellent anti-wear and load-bearing properties as well as suitable viscosity.
