Hello everyone, I'm Xiao Li. Some time ago, I went to do maintenance for my car, and met a Sylphy who was also doing maintenance, he used fully synthetic engine oil, and he had a simple conversation, I disagreed with him very much about changing the oil viscosity, because the viscosity of the oil used in his own car was not right, and the age of the Sylphy car was not large, so he had to use 10W-40 oil, which was used in the north in winter, and the engine may be difficult to start.
At that time, I told my friend to get me the SP level 0w-20 fully synthetic engine oil, and then the owner of the Sylphy smiled when he heard it, in fact, there is no need to change the fully synthetic if you drive less, many people are stupid and have more money to do this. I just responded to him at the time with a perfunctory remark that was not bad for money, but I found that many novice friends have this misunderstanding in the maintenance of the car, and today I will tell you that only 2,000 kilometers a year, is it necessary to use fully synthetic engine oil.
Not to mention how many kilometers you drive in a year, fully synthetic motor oil is essentially different from ordinary mineral oil, fully synthetic motor oil is a synthetic motor oil, and its oil film quality is higher. When the engine is running, the higher the quality of the oil film, the better the protection of the engine, which has nothing to do with how many kilometers you drive in a year.
The engine needs organic oil to lubricate when it runs, and the quality of the engine oil determines the degree of wear and tear of the engine, and the engine with fully synthetic oil will definitely be healthier. Let me give you an example, can you run in sneakers the same way as running in sandals? You can't say that you only run 2 kilometers a day, you don't need to wear sneakers, right? Although you can run 2 kilometers in sandals, your feet will definitely be more sinful. It's not a big problem to use mineral oil in the engine and you can maintain it on time, but in the long run, it must be better to use fully synthetic engine oil.
There will be more impurities in the mineral oil, although it is only 2,000 kilometers a year, and it is far from reaching the replacement cycle, but the engine is in a state of high temperature during the operation of 2,000 kilometers, and if there are more impurities in the oil, it will become carbon sludge in a high-temperature state. These things will have a strong stickiness, adhere to the various parts inside the engine, and these things can not be discharged when changing the oil, over time will cause the engine running resistance to increase, fuel consumption will become higher, and the power will become worse.
The fully synthetic engine oil is a synthetic engine oil, the quality is better, its molecular arrangement is more uniform and the impurities are less, just like the rice we eat, each grain is uniform, full and clean, not only is it not easy to form sludge inside the engine, but also can assist in cleaning the inside of the engine, so do you say it is necessary to change the fully synthetic engine oil? and only drive 2,000 kilometers a year, you use mineral oil maintenance I think it will be more wasteful of money.
The life of mineral oil is generally 5,000 kilometers or 6 months, this oil is a very ordinary engine oil, I do not recommend that you continue to use it after 6 months, whether you drive enough 5,000 kilometers or not, I recommend replacing it when it expires, because I have suffered losses. If a bottle of mineral oil is 150, you have to change it twice a year to be 300, right? And a bottle of fully synthetic engine oil is also more than 300, you can change it once a year, or even you can change it once a year and a half, which virtually saves money.
I myself used the kind of fully synthetic engine oil I said at the beginning of the article to basically change it after more than 10,000 kilometers, and if I drove less than 10,000 kilometers, I would change it once a year and a half. The car I use now is less than 100,000 yuan, just a second-hand car of 60,000 yuan, and I don't drive much now, but I still choose to use a good engine oil, not for anything else, I hope it is durable, after all, there is no money to change the car now.
