This is very difficult for the first-time drivers, because they do not have much driving experience, can not make accurate judgments from the driving conditions of the car, and can only blindly change from the "XXXX km" of the car dealer or the manual.
In fact, no matter how many kilometers the car travels, as long as it feels that the shift is not smooth, the noise is getting bigger, the idle speed of the hot car is decreasing, the acceleration performance is degraded, or the oil is blackened, the oil should be changed.
2. Use winter and summer oil separately according to the season, and do not use it across seasons.
Although many oils on the market (including some international brands) indicate that the oil can be used in winter and summer (such as 10W40 or wider), this is only a commercial need of the business.
If anyone believes that fish and bear's paw can have both, then you can use it boldly.
3, you must choose the right oil, do not trust the car dealer's special oil.
When buying a car, any car dealer will emphasize the necessity of using special oil to the customer. Even if the car dealer does not add his special oil, he will not give the warranty to the owner. The special oil of many car shops is a few yuan of money, but only a "XX car-specific" sign on the outside, now you understand why the car dealer must ask you to add his special oil.
4, to choose oil according to the condition of the car, do not blindly follow the trend.
According to the matrix, the oil can be divided into three major categories: vegetable oil, mineral oil and synthetic oil.
Vegetable oils are only used in special occasions, mineral oils are used in ordinary motorcycles, and synthetic oils are used in medium and high-end vehicles.
If your car is nearing retirement, there is no need to use high-grade oil. The idea of ​​using high-grade oil (including various additives) to extend the life of the vehicle is just as impractical as eating an ginseng for an 80-year-old man.
Even if it is synthetic oil, don't be too superstitious. Its performance is indeed stronger than mineral oil in some respects, but it is by no means immediate. The idea of ​​adding low-end cars to synthetic oils and car addiction is not feasible.
A famous car is a famous car, unless you believe that you can build a car with synthetic oil to win the championship in Formula One.
Good oil is like a nutritious meal for people. It is enough to do it. Don't overdo it, and keep you prolonging.
5, to use motorcycle oil, do not mistake the car oil.
According to the use, the motor oil can be divided into two categories: motorcycle oil and automobile oil.
Due to the different lubrication methods, operating temperatures and functions, it was decided that motorcycles could not use motor oil.
Some car owners misused car oil (or ordinary motor oil) and found no obvious problems and came to a conclusion: the oil can be added casually.
In fact, this effect is long-term. Just as we have to talk about hygiene when we eat, but the beggar often eats dirty things and does not see him die on the spot, but people believe that the beggar does not live longer.
6, the engine oil should be selected according to the working mode of the engine, not the second and fourth flush machines. The principle of the two-flushing machine and the four-cylinder machine are different, and the lubrication method is also different. Therefore, do not misplace the engine oil.
7, to add by quantity, not to be more good.
Some drivers believe that the more oil, the better the lubrication and heat dissipation conditions.
In fact, too much oil will increase the pressure inside the crankcase, and it will also burn into the cylinder to cause carbon deposits, which will damage your car early. So don't exceed the highest oil level.
In fact, in the end, you can solve the problem by changing the oil here. There are spark plugs, piston rings, etc. It is you who lost the car in the early days. He is the one who makes money in the future.
