Hello everyone, I'm Xiao Li. How to tell if the oil needs to be replaced? It's a very easy thing to do. However, many novice friends lack some common sense knowledge about oil, resulting in frequent oil changes and waste of a lot of money. Today Xiao Li will come to tell you how to judge whether the oil needs to be replaced, share 2 common situations, I hope my explanation can help everyone. If you are interested in the content of car maintenance and car use, don't forget to pay attention to Ha.
In the first case, it is not recommended to change the oil once a year when the vehicle is idle for a long time. In this case, although the vehicle is idle and does not consume the life of the oil, it is also necessary to change the oil to a certain extent. As long as you pay a little attention, you will find that the first thing that many long-term idle used car owners do is to change the oil. This is mainly because the oil will deteriorate after a long time of poor protection, the lubrication effect will be greatly reduced, and even lead to engine wear.
When the oil is not opened, it can be stored for 4 to 5 years in a dry and cool place, for example, the shelf life of Mobil's oil is 5 years. However, after the oil is opened, the shelf life is greatly shortened, and it can only be stored for 6 months to a year, and some oil manufacturers will explain that the oil after opening is recommended to be used up within one year after being stored in a dry and cool place. Although the vehicle is idle, the inside of the engine is not completely sealed, and the oil will slowly deteriorate in the oil pan, thus losing the original lubrication effect. Therefore, in order to ensure that the engine can operate normally, it is also necessary to ensure that the oil is changed once a year during the idle time of the vehicle.
In the second case, the oil needs to be changed when it reaches its service life. The service life of the oil is calculated according to the mileage of the vehicle, and the service life of different models of oil is different. For example, the common mineral oil 5000 km to change, semi-synthetic oil 7000 km change, full synthetic oil is 10000 km change, but the same is a full synthetic oil, Mobil's 0W-20 oil has been able to do 20,000 km before replacing.
Many people go to the 4S shop for maintenance, and it is recommended to change the oil in 6 months or 5000 kilometers. This is actually a wasteful approach, because many cars use fully synthetic oil when leaving the factory, such as the Toyota Vios in my hand is the fully synthetic 0W-20 oil, in fact, it does not need 5000 km to change, its service life is 10000 km. But if you've run 10,000 kilometers in less than 6 months, it's time to change the oil as soon as possible.
In addition to the above 2 situations, many models will have a reminder to change the oil on the dashboard of the car, which is a good procedure set by the manufacturer according to the current model of the applicable oil combined with the odometer of the vehicle, and the mileage will remind the owner to maintain the vehicle as soon as the mileage arrives. As long as the oil is replaced in strict accordance with the model required above in the user manual, then it is completely possible to change the oil regularly according to this reminder. For example, Buick's Yinglang user manual recommends the use of 0W-20 fully synthetic oil, and its dashboard design is 10,000 kilometers to remind the oil to change. Therefore, if you use this fully synthetic oil, you can completely wait for the vehicle to prompt and then change the oil, if the figure is cheap to use semi-synthetic oil, then you need to change the oil when the oil service life is still 30%, this time it is said that 7000 kilometers, the dashboard will not have a prompt but it should also be changed.
The above is Xiao Li's summary of how to judge whether the oil needs to be replaced, I hope my explanation can help everyone. If you think what I'm saying is useful, don't forget to give me a thumbs up. Pay attention to the car Xiao Li, every day will share a phase of the car car small dry goods, thank you.
