What is the Difference Between Transmission Fluid and Engine Oil?
1 Answers
The differences between transmission fluid and engine oil are as follows: 1. Different Environments: Transmission fluid, also known as gear oil, is used in the transmission system. It is a type of transmission lubricant designed for lubricating gears in transmissions, reducers, and differentials, operating at relatively lower temperatures. On the other hand, engine oil is used inside the engine to lubricate its internal components, enduring high temperatures and pressures, thus requiring higher oxidation resistance and stronger shear stability. 2. Different Functions: Both serve lubrication purposes, but transmission fluid prevents gear surface wear, sintering, and other issues, extending service life and improving power transmission efficiency. Engine oil, meanwhile, performs functions such as cleaning, lubricating, and cooling within the engine.
