What is the Difference Between Engine Oil and Transmission Oil?

[LaCarmen]

Engine oil and transmission oil differ in viscosity and the temperatures they can withstand. Engine oil is used for the normal operation of the engine, enduring the highest temperatures and having the lowest viscosity. Transmission oil is used for the transmission, enduring lower temperatures and having a higher viscosity than engine oil. Details about engine oil and transmission oil are as follows: 1. The main function of automotive transmission oil is to keep the gear shift system clean, providing lubrication and cooling. During driving, the gears operate at high speeds, generating heat through friction, which necessitates the use of gear oil for lubrication and temperature reduction to ensure the vehicle's normal operation. 2. The primary function of engine oil is to lubricate the engine system, providing lubrication, cooling, sealing to prevent leaks, rust and corrosion prevention, as well as shock absorption. It can be said that the condition of the engine oil directly affects the performance and lifespan of the engine, making it a crucial automotive consumable.
