👉 Car fluid, also known as engine oil, is a crucial component in vehicle maintenance that lubricates moving parts within the engine, reducing friction and wear while dissipating heat. It also helps protect against corrosion by forming a protective film on metal surfaces. Different types of car fluid, such as base oil, oil filter oil, and transmission fluid, serve specific functions within the engine, ensuring optimal performance, efficiency, and longevity. Regularly changing the fluid as per the manufacturer's recommendations is essential to maintain the vehicle's health and prevent costly repairs.
