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

Motor oil, also known as engine lubricating oil, is called the blood of the car. Regularly changing the engine 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 secure on the road. So how often is it better to change your car’s engine oil?

When should the car engine oil be changed?

Whether the engine oil needs to be changed depends on two hard conditions, one is the mileage and the other is the usage time. No matter which time is reached, maintenance is required.

The maintenance intervals are also very different when using different engine oil types. Mineral oil requires maintenance every 5,000-7,500 kilometers or every six months, semi-synthetic oil needs maintenance every 8,000-10,000 kilometers or once a year, and fully synthetic oil needs maintenance every 10,000-15,000 kilometers or once a year.

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

The oil replacement cycle is also related to the type of engine oil.

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

How many kilometers does a car run to change the oil?

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

If you are using original engine oil, it is recommended to change the oil according to the intervals indicated in the car maintenance manual. If you buy the engine oil yourself, you need to check whether it is mineral oil, semi-synthetic oil, or fully synthetic oil. The replacement intervals vary depending on the type.

In urban driving, long-term slow speed, stop-and-go driving, and short-distance driving of less than 8km and other unconventional driving conditions, it is recommended to shorten the replacement cycle. Because this driving situation will affect the life of the engine.

If you encounter severe weather or environment, such as heavy snow, sandy roads, etc., it is also 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.
