Can Engine Oil and Transmission Oil Be Used Interchangeably?
1 Answers
Engine oil and transmission oil cannot be used interchangeably, as their friction systems are different. Engine oil serves functions such as lubrication, cleaning, cooling, sealing, wear reduction, rust prevention, and corrosion protection for the engine. Transmission oil, used within the transmission, is a cleaning product that maintains the transmission system. It is categorized into automatic transmission fluid (ATF) and manual transmission fluid. ATF is specifically designed for automatic transmissions, while manual transmission fluid is tailored for manual transmissions. The quality of transmission oil directly impacts the transmission's performance. Methods to determine the quality of transmission oil include: 1. Observing the oil's fluidity; 2. Checking for bubbles; 3. Assessing the oil's viscosity; 4. Smelling the oil's odor.
