The 'golden time' to change car oil at the perfect time

1. Time to change engine oil

The effect of this oil is to protect the engine from wear, prevent rust on engine block parts, reduce friction, prevent deposits and ensure the machine's performance.

The color of engine oil is usually dark amber, when the oil is dirty it will turn dark brown, this is when the lubricating oil needs to be replaced. Previously, manufacturers recommended that car owners should change the oil after 5,000 km, but with new cars and using new types of oil today, the manufacturer's recommendation is increased to 12,000 - 14,000 km.

When changing the oil, you should also pay attention to changing the oil filter because when circulating in the engine, the oil must pass through the oil filter, where the filter will retain soot that can wear out machine parts.

2. Time to change power steering fluid

When turning the steering wheel, the valve sends this oil into the cylinder, then the piston of the power steering system will compress and move the oil inside the cylinder to help reduce the force applied to the steering wheel; therefore, the driver does not have to use much force on the steering wheel to move the car in the right direction.

Power steering fluid is usually clear or red in color. When the fluid turns dark amber or dark red, it is time to change it. However, due to its characteristics of not having to bear much force and being sealed in the cylinder of the power steering system, it does not wear out, so this fluid can be changed after 100,000 - 130,000km.

3. Time to change brake fluid

Brake fluid has the main function of transmitting force, the force from the brake pedal is transmitted through the high pressure pump containing oil to the four wheels. When used for a long time, the brake fluid becomes damp and loses its effectiveness, so when the brake loses its accuracy, it must be replaced immediately to ensure safety.

The color of brake fluid is usually transparent. When the brake fluid turns moss green, the condition of the fluid is very "bad", the vehicle is no longer safe to move... Manufacturers recommend that car owners should replace it after 3 - 4 years of use; if you often travel on mountain passes and have to use the brakes, the replacement time will be faster than recommended.

4. Time to change gearbox oil

The function of this type of oil is to lubricate the gears in the gearbox; the oil does not have to bear load, compression and operates in a closed space so it does not wear out. Therefore, you do not need to pay too much attention to this type of oil and just check the loss to make sure the gearbox has no problems.

Transmission fluid should be replaced every 130,000 - 150,000km; the fluid is bright red when new, turning dark red when it is due for a change.

5. Time to change coolant

The coolant after absorbing heat will be pumped through the radiator and the fan here will lower the temperature of the coolant and circulate it again from the beginning.

The vehicle's cooling system must constantly work under high temperatures and pressures, so corrosion also appears over time... Manufacturers recommend changing the coolant every 2-3 years, or after 40,000km to ensure the engine does not overheat during use.

* Practical uses of motor oil

• - Cooling:Lubricating oil dissipates heat generated by friction and fuel combustion up to more than 350°C in the piston area.
• - Cleaning:Engine oil helps clean the internal parts of the engine.
• - Sealing:Engine oil forms a seal between the piston rings and cylinder walls to maintain pressure in the combustion chamber and minimize the leakage of combustion gases into the crankcase.
• - Contains residue:Lubricating oil will be the place to contain the residues that are kept suspended in the oil, avoiding the formation of large residues that can clog the oil filter.
