Are Transmission Fluid and Engine Oil Interchangeable?
1 Answers
Transmission fluid and engine oil are not interchangeable. Transmission fluid is primarily used to keep the gear system clean, ensure the normal operation of the transmission, and extend the lifespan of the transmission components. Engine oil, on the other hand, is a lubricant for the engine system, possessing certain anti-oxidation, anti-wear, and anti-corrosion properties. In theory, the functions of transmission fluid and engine oil are similar—both are lubricants that primarily provide lubrication, cleaning, rust prevention, and heat dissipation. Engine oil consists of two parts: base oil and additives. The base oil is the main component of the lubricant, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, imparting certain new characteristics, making them an essential part of the lubricant.
