Some car owners always care about cars, but many riders use wrong maintenance methods, and the result is naturally counterproductive. Compare it and correct it quickly. 1, too much oil When the oil is insufficient, the bearing and the journal will be poorly lubricated, which will aggravate the wear and even cause the burning of the shaft. But too much oil, the engine also has to fail, that is, crankshaft shank, large end of the connecting rod will produce violent agitation at work, will increase the engine internal power loss, but also make the oil splashed on the cylinder wall increased, resulting in burning row Oil failure. Therefore, the oil should be controlled between the upper and lower score lines of the oil dipstick. 2, blindly like to import tires Some riders particularly like "imported" tires, but tires suitable for European road conditions are often difficult to achieve good performance in China, especially the impact resistance of the tire side is particularly "squeegee", and it is easy to cause tires to rise from the side. In fact, after the tires of many foreign brands are jointly produced in China, they have added a layer of cord fabrics on the side of the tire according to the domestic road conditions, thereby increasing the impact resistance of the sidewalls. 3, free increase in the car equipment The car is like a mobile home to the owner. The pursuit of comfort and luxury in the car is understandable. However, many owners like to install various equipment in the car. If the car is not handled properly, it will affect the car's performance. And manipulation, easy to leave sequelae or affect traffic safety. 4, under the sun washing car paint After sun washing, the car body will soon be dried, but at the same time, it will be easily damaged. Because under the sun, the convex lens effect of water will cause local high temperature on the top layer of the paint, and it will take a long time. It will lose its luster. Car waxing is best done under sheltered conditions, or in the morning or in the evening on a cloudy or sunny day. 5, tank "open pot" busy add water The water tank “opens the pan†and many drivers worry that the temperature of the engine will rise further and turn off the water immediately. This is wrong. The correct method is: stop immediately, and turn off the engine after the temperature of the cooling water decreases. If the cooling water is insufficient, add it slowly. 6, long-term without a car or short-distance car After the increase in car costs, many car owners started to drive less, and some only drove when they were on vacation. In this way, the surfaces of the transmission components such as the engine and the transmission are rusted due to their direct contact with the air. The best way is to let the car run for thirty to forty minutes every few days. In addition, long-term short-distance car is also easy to hurt the car, should run long distances.
