Eight Tips for car maintenance six tips for beginners
Sihai: what are the daily car maintenance items? Automobile is a very complex large machinery, in the operation of the mechanical parts will inevitably produce wear, coupled with external human, environmental and other factors, resulting in the loss of the car. According to the driving condition of the car, the manufacturer will make corresponding car maintenance items, so what are the problems worthy of our attention and understanding during the car maintenance?
1. Lubricants should be affordable
As one of the most important automobile protectors, the choice of high quality lubricating oil can effectively protect the engine, reduce wear and make the vehicle have better use economy. But now there are more and more brands of lubricating oil, so many of the main trunk of cars are imported, and they have to be the most expensive. In fact, this is not necessary. The price of imported oil is 30% - 40% higher than that of domestic famous brand, and more than twice as expensive as that of general domestic oil. So it is not necessary to pursue famous brand with high price.
2. Do not blindly pursue high standard oil
Gasoline grade is only a parameter to mark the antiknock ability of gasoline. It has no inevitable relationship with whether the gasoline is clean and fuel-efficient. It is not that the higher the gasoline grade is, the better it is. Even high-end cars are not equal to the need to increase the gasoline grade. What oil should be added should follow the oil standard in the instruction manual, so that the compression ratio coefficient of the automobile engine can adapt to the gasoline antiknock coefficient, which cannot be measured by price.
3. Scientific and reasonable maintenance
Automobile maintenance cycle refers to the interval mileage or time of automobile maintenance. High maintenance frequency is not a bad thing, it can more effectively guarantee the performance of the vehicle. At the initial stage of using the car, it is mainly for normal maintenance, with relatively low cost; when the car is used for a certain period of time or after a certain mileage, it will enter the maintenance period, with relatively high cost. However, when determining the maintenance period, the maintenance period should be adjusted properly according to the maintenance period recommended by the automobile manufacturer, combined with the technical conditions and actual use conditions of the automobile itself. In general, the maintenance period of new cars in good condition can be extended properly; in case of poor condition or poor service conditions, the maintenance period shall be shortened appropriately.
4. Clean the filter frequently
Always pay attention to cleaning the car filter. Don't look down on it. It directly affects your car's fuel consumption. In the process of using the automobile internal combustion engine, the impurities such as dust will be mixed into the engine oil constantly. At the same time, the oxidation effect of air and combustion exhaust gas on the engine oil will gradually generate colloid or oil sludge, which will not only accelerate the wear of parts, but also easily cause the blockage of oil circuit. So clean the car's air filter regularly until you replace it with a new one.
5. Tires should be inflated properly
Tire pressure correction is the most important part of safety inspection. Too low tire pressure will lead to abnormal wear or tire internal damage. Too high tire pressure will make the tire and rim more vulnerable to the impact of uneven road surface and deformation, and even lead to tire blowout. The tire pressure must be checked regularly. In addition to the spare tire, other tires must be checked at least once every two weeks. The tire pressure must be checked when the tire is cold, otherwise the high temperature will increase the tire pressure and the measurement is not correct.
6. Wash the car in rainy days
Washing the car in rainy days is not only because the car is dirty, but also to protect the paint. It is necessary to wash the car in rainy days. Those car owners who pay attention to car maintenance will often wash the car, so as to remove the dust, asphalt, resin, etc. adhering to the paint surface and keep the paint smooth. If another layer of oily protective film is applied to the paint surface, it can also prevent rain from directly corroding the paint surface. And it's better to wash the car by yourself. If you insist on washing the car by yourself for a long time, you can save a lot of money.
