The owner often reflects why it is to repair a minor problem, 4S shop was able to pull out a high price maintenance list? Look carefully at this list, it really makes people laugh and laugh. Obviously, I feel that air-conditioning is not cool enough, and how these "engine-clear carbon" and "fuel-oil circuit cleaning" items are incredible? This makes me think that the situation is very similar to the current hospital, obviously it is a bit of a headache. However, doctors can arrange dozens of inspection items, and the name “excludes the causes one by one†and “data support diagnosis results†seem to be for the sake of patients, but actually maximize the benefits.
After tossing around and catching a cold, the cold is still a cold. The medicine is still the medicine, but the inspection fee is more expensive than the medicine. The water truck engine and the oil road contamination do exist, but there is no need for dismantling and cleaning in the absence of obvious symptoms. If you are worried, regular use of special fuel detergents can reduce these situations.
In order to maintain the brightness of the water truck paint surface, the manufacturer's manual will also mention waxing the water tanker, but there has never been any manufacturer will advise the owner to seal construction. On the one hand, the sealing glaze industry does not currently have uniform technical standards and construction specifications. On the
Other hand, the polishing prior to sealing the glaze has an effect on the original paintwork. New waterwheels should not be particularly done. The most important factor should also be that after sealing the glaze will affect the repair of the paint. The partial paint on the glazed paint will cause terrible orange peel effect.
Nitrogen is used to inflate tires for general purpose cars and light trucks. Based on the characteristics of inert gases, the benefits are good, but they are minimal. Not to mention, because it was impossible to empty all the air originally present in the tire before it was filled with nitrogen, so it was impossible to fill nitrogen with true high purity. But what is the amount of nitrogen originally in the air, you know? 78% by volume, so how much difference can you make with nitrogen compared to normal inflation? In addition, tire manufacturers also emphasize that regardless of the use of air or nitrogen, it must be The tires are regularly maintained and the standard tire pressure is maintained. The use of nitrogen inflation does not replace the maintenance of daily tire inflation pressure.
In addition, compared with general high-pressure air, high-purity nitrogen is oxygen-free and contains almost no water and oil. It has a low coefficient of thermal expansion, low thermal conductivity, and a slow temperature rise, which reduces the rate at which tires accumulate heat. It has non-flammable and non-flammable properties. Characteristics, so that the probability of puncture is effectively reduced. Because nitrogen has certain inert gas properties, it is not flammable and has good thermal stability. Typically used in very professional tire applications or harsh environments such as F1 racing tires and aircraft tires. Many people listened to it and found it reasonable to spend a lot of money on filling their cars with nitrogen. How difficult it is to say clearly, but many people feel at ease.
Do not dare to say that the anti-wear agents on the market are fake, but those so-called nano, aerospace technology you better not believe, as often played on TV, after using an anti-wear agent, the oil row Air can continue to drive hundreds of kilometers of advertising videos, and you'd better not believe it. Advertising dare to shoot, but because manufacturers know no one dares to do so. Be careful about driving and diligently changing the oil than any anti-wear agent.
Lao Lin bought a used car and thought that it should be maintained. At the repair shop, the staff recommended him an engine nano-anti-wear agent, which claims to reduce fuel consumption and extend engine life. The most important thing is that in the event of an oil spill accident, anti-wear agents can fully guarantee that the water truck continues to travel for several hundred kilometers. Seeing such magic, Mr. Wang will also save money. Things are so simple,
A few days in a foreign business trip, due to poor road conditions, the car's oil pan was smashed by stones, the oil was really leaking, but there was no maintenance factory near the time, and the promotion of nano anti-wear agents was vivid. Mr. Wang intends to drive the car home and then repair it. Only two kilometers away, only a loud crack, the engine was declared scrapped.
The vehicle still has to be maintained and repaired immediately. If there is something wrong with it, it will be repaired immediately. If you love it, it will bring you more benefits!
