When should the car's engine oil be changed? How often should the car's engine oil be changed?

Motor oil, also known as engine lubricant, is called the blood of the car. Regularly changing the motor oil of your car is one of the maintenance methods, which can extend the service life of the engine and make it safer and more assured on the road. So how often should the car's motor oil be changed?

When should you change your car's engine oil?

Whether or not to change the engine oil depends on two hard conditions: one is the mileage and the other is the usage time. No matter which one is reached, maintenance is required.

The maintenance intervals for using different types of engine oil are also very different. Mineral oil requires maintenance every 5000-7500 kilometers or every six months, semi-synthetic oil requires maintenance every 8000-10000 kilometers or once a year, and fully synthetic oil requires maintenance every 10000-15000 kilometers or once a year.

How often does a car's engine oil need to be changed?

The oil change cycle also depends on the type of oil.

At present, most of the motor oils on the market are still mineral oil and semi-synthetic oil, which are generally replaced every 5,000 kilometers. The other type of fully synthetic motor oil has better performance than ordinary mineral oil in low-temperature start-up protection, high-temperature viscosity retention, anti-oxidation, cleaning, etc., and has a longer life. Another point is that fully synthetic oil can be used in a wider range of temperatures and can be used in extremely high or extremely low temperature environments, reducing the probability of changing the oil due to ambient temperature. This can be replaced after 10,000 kilometers. There is also a more compromised semi-synthetic motor oil, which also compromises performance and price, and is generally replaced after 7,500 kilometers.

How many kilometers does it take to change the oil?

There is no fixed standard for the time to change the oil in a car. After all, the way each car is used, each person's driving habits, the type of oil and mileage standards, as well as the local environment, etc., will affect the time to change the oil.

If you are using original engine oil, it is recommended to change the engine oil according to the cycle specified in the car maintenance manual. If you buy the engine oil yourself, you need to see whether it is mineral oil, semi-synthetic oil, or fully synthetic oil. Different types have different replacement cycles.

In urban driving, long periods of slow speed, stop-and-go driving, short distance driving below 8km, etc., it is recommended to shorten the replacement cycle, because such driving conditions will affect the life of the engine.

If you encounter severe weather or environment, such as heavy snow, sandy roads, etc., it is recommended to replace the oil filter in advance because it is easy to clog the oil filter and increase the impurity content of the oil.
