4 types of oil in cars that need to be checked and replaced periodically

In addition to coolant, windshield washer fluid, etc., on current internal combustion engine cars, there are many types of specialized oils used for different parts. For example, engine oil, gearbox oil, brake oil, etc. Over time and in the environment in which the car is used, these oils often deteriorate and need to be checked and replaced.

If car users are negligent and subjective in not adding or replacing the oils in their cars according to the manufacturer's recommendations, over time it can affect the stability of parts such as the engine, gearbox, brake system, steering system, etc. However, usually, in addition to engine oil, not everyone who uses a car knows which oils in their car need to be replaced, or what the condition of the oil is, or how many kilometers the car has run before it should be replaced (!?)

Engine oil

Engine oil is an important solution that helps maintain the operation of the engine system through the lubrication mechanism, reducing friction and cleaning mechanical parts such as pistons, cylinders or crankshafts. After a long time of use, the engine's fuel combustion process can create soot, dirt... mixed in the oil, causing the oil to degrade and reduce its lubricating ability.

Therefore, according to the recommendations of car manufacturers, depending on each type of car, car users need to monitor, check and change the oil periodically every 5,000 - 10,000 km or about 4 months to ensure the engine always operates stably.

Train oil

Gear oil is a solution that lubricates the gears inside the car's gearbox. For the gearbox to always work well, the quality of the gearbox oil must be guaranteed. With automatic gearboxes, gearbox oil also contributes to ensuring the stable operation of the hydraulic clutch. The fact that gearbox oil often has to work in a high temperature environment can easily cause the molecules in the oil to break down, no longer ensuring working efficiency.

In addition, like engine oil, soot, dirt and metal dust from the operation of the gearbox will mix in the oil, causing the oil to gradually thicken and lose its lubricating effect. Therefore, car gearbox oil also needs to be checked and replaced periodically. According to the manufacturer, for manual transmission cars, gearbox oil should be changed after every 40,000 - 50,000 km of use and after every 60,000 - 150,000 km for automatic transmission cars.

Brake fluid

Brake fluid plays a role in transmitting force from the brake pedal through the brake calipers (brake pads) on the 4 wheels. Brake fluid also needs to be replaced periodically for the braking system to operate optimally. Therefore, it is necessary to regularly monitor and check the brake fluid level. If the amount of fluid in the tank is reduced or drops below the minimum level, it should be replaced. In addition, it is necessary to pay attention to the change in color of the brake fluid. If the color of the brake fluid turns brown or black, it should also be replaced. Normally, if there is no loss, brake fluid replacement is usually done at least once every two years. However, the time may vary depending on the condition and needs of the vehicle.

Power steering fluid

Power steering fluid and shock absorber fluid function as a hydraulic pump to help the driver control the steering wheel more easily and smoothly, while contributing to smoother vehicle operation. Power steering fluid also plays a role in maintaining the working rhythm of the components in the steering system and shock absorber system of the car. Currently, many new car models have switched to electric power steering systems, but many cars still use hydraulic power steering systems. Power steering fluid also needs to be checked and replaced periodically or when the oil color has turned brown or black. In particular, it is necessary to monitor and check the parts containing power steering fluid to prevent oil leakage, leading to loss and causing the steering system and suspension system to operate ineffectively.
