Choosing good engine oil can make the car more durable and more powerful. Good engine oil, especially fully synthetic engine oil, not only protects the engine and reduces the number of oil changes, but also saves gasoline expenses. Therefore, it is twice as expensive as ordinary oil and is the best choice for many car owners.
Under normal circumstances, when selecting engine oil, you should pay attention to the following four elements:
1. The selection of oil should be based on the requirements of the engine. It is not necessary to use too high-grade oil on engines with lower requirements, nor can you use lower-grade oil on engines with higher requirements.
2. Multi-grade oil should be selected as much as possible. Multi-grade oil has a better protective effect on the engine due to its savings, long life and high efficiency. Based on the characteristics of multi-grade oils, premature blackening and lower oil pressure than ordinary oil may occur during use, which is normal.
3. Some domestically produced brand-name engine oils are of quite good quality, and their prices are much lower than similar imported products. You can use them with confidence and there is no need to blindly pursue “foreign oil”.
4. If the engine is in good condition and the seasonal temperature is low, oil with lower viscosity should be used as much as possible to make the oil passage smooth. For example, in hot seasons or under severe engine wear, selecting high-viscosity engine oil will help form oil films and reduce engine wear.
Tip: There are hundreds of engine oil brands on the market. Choose a better grade of oil. Although it is a bit expensive, it will protect the engine parts better.
The amount of oil should be slightly lower than the scale on the oil dipstick, and do not overfill it.
There are several issues to pay attention to when changing the oil yourself.
Under normal driving conditions for new cars, if synthetic oil is used, the oil can basically be changed every 10,000 kilometers, and some can even be dragged for 20,000 kilometers. Car maintenance professionals believe that “normal driving” means driving frequently on the highway with little stop and go. However, if you often drive in the city, there are traffic lights everywhere you go, traffic jams will occur at all times, and most of the distance per trip will not exceed more than ten kilometers. This driving method belongs to “lossy driving.”
In the case of “lossy driving”, engine wear is relatively large and the oil requirements are relatively high. Therefore, it is recommended to shorten the interval between oil changes to effectively protect the engine.
Tip: It is difficult to decide whether the oil should be changed by naked eyes or touch. However, after long-term use, the oil will accumulate a large amount of impurities. If the oil is not replaced with new oil in time, these impurities will wear out the engine and shorten the life of the car.
JinMobil 0W40 engine oil and Mobil No. 1 0w40 engine oil are really good. Fully synthetic engine oil does have very good performance and good liquidity. Whether it is cold start in winter or high temperature resistance in summer, it is excellent, and the oil change cycle is long, which can protect the engine to the greatest extent. However, fully synthetic engine oil is not suitable for small cars worth tens of thousands of yuan.
