Engine oil plays a role in lubricating the engine, reducing wear, preventing rust and corrosion, etc., and is known as the "blood" of the car. Changing the oil is an important part of car maintenance and is very critical to the driving and life of the car. The timing of changing the oil is also very important, change too early, feel a waste of money, change too late, it is not good for the car. So how often should you change the oil?

Is "5000 km oil change" the standard answer?
When it comes to oil change intervals, many car owners will answer "once in 5000 kilometers", is this true?
In fact, the oil change cycle is affected by many factors, not only depending on the mileage, but also on the type and quality of oil, driving habits, road conditions, season, and the newness of the car. Generally speaking, the oil change cycle specified in the car manual is long, and different situations should be considered in the actual use process.
* Depends on driving conditions
If your car is not used frequently, you can decide whether to replace it according to the mileage and shelf life of the oil.
If you commute by car and are constantly stuck in traffic, it's different.
In the congested road conditions of the city, the car frequently turns off and starts, which puts great pressure on the oil. After the performance of the oil exceeds the critical value, it cannot effectively protect the engine. In this case, the replacement cycle should be shortened.
If the owner has bad driving habits such as long-term sharp acceleration and frequent sharp braking, it will accelerate the wear of various components in the car, and the replacement cycle should be shortened under the premise of the mileage of oil use.
If driving in dusty areas or low temperature areas for a long time, the oil change interval should also be shortened. On the contrary, if the environment is clean and the air is clean, the oil change interval can be appropriately extended. In areas with poor road conditions, the oil replacement cycle should also be shortened.
* Look at the old and new of the car
If it is a new car just bought, its parts need to be run-in, the friction generated will increase, and the oil consumption value of the new engine can only be reached after running for a period of time. At this time, the oil is used quickly, and the frequency of replacement is naturally high.
If it is an old car that has been driven for three or four years, the friction between the parts is not large, and the lubrication efficiency of the oil is high. As long as the working condition of the engine is normal and the use environment is good, the oil change interval of 5,000 kilometers is completely feasible.
* Look at the type of oil
From the perspective of time, mineral oil generally begins to oxidize after about 3 months of exposure to the air, and its function is reduced. Semi-synthetic oil is 6 months, fully synthetic oil can be 1 year.
In terms of mileage, mineral oil generally begins to decay at 5,000 km. Semi-synthetic engine oil is generally 7500 km, and fully synthetic engine oil is generally around 10000 km.
Therefore, specific issues still need to be analyzed on a case-by-case basis and cannot be generalized. If you still have questions about when to change the oil, you can buy the oil test paper, the price is not expensive, so that you can determine more clearly and conveniently whether you need to change the oil!
