There is a saying that it is easy to buy a car and difficult to maintain a car. For card friends who are out of the car all year round, raising a car is a university question, and there will be a big hidden danger if you are not careful. However, some card friends just don't study seriously and play smart. Take a look at the following four points, you have not been tricked!
Add a small amount of oil
Small oil is a self-employed small gas station, the most obvious difference with PetroChina, Sinopec is that the oil price is relatively cheap, but the source is unknown, the quality of oil can not be guaranteed. But despite this, the market for small oils is promising.
Oil cost is the majority of the daily expenditure of Kayou, aside from the increase in oil prices, the general diesel price of PetroChina and Sinopec is about 6 yuan / liter, and the small oil is about 4 yuan / liter. The difference of 2 yuan is extremely attractive in the sluggish freight market, and adding small oil is the choice of the vast majority of card friends.
However, there are many impurities in the small oil, and if it is used for a long time, it will easily cause diesel filter blockage, fuel injector blockage, engine carbon deposition, etc., increase the content of harmful gases in the exhaust gas, and then post-process the sensor alarm, and the car limits the torque and speed limit. Therefore, from the perspective of vehicle maintenance, it is not recommended that card friends add small oil, especially for the delicate national six post-processing.
Urea is water-mixed
Starting from China IV, diesel vehicles must use vehicle urea, and urea plays a catalytic role in effectively controlling the problem of exhaust pollution. Although the price of urea will not be more expensive than the price of oil, or even much cheaper, it is impossible to stand that some more thrifty card friends will mix water into urea to reduce the amount of urea used and save costs.
However, after the urea is added to the water, the concentration will be reduced, the function will be weakened, which will lead to damage to the urea pump, damage to the urea nozzle, engine weakness, emissions exceeding the standard, etc. Maybe you will say that this is how you operate, and there is nothing wrong with the car. I'd like to say wait, there will be.
However, this method has not been used since the beginning of China VI, and The national VI vehicle has added a new vehicle urea liquid quality sensor, and it is necessary to use regular qualified urea to operate normally.
Fix the car to go to the street shop /do it yourself
Often walking by the river where there are not wet shoes, the car will always fail after driving for a long time. However, the number of regular manufacturer repair stations is too small, and the second is that the charges are too high, and many card friends do not like to go. In comparison, roadside maintenance shops are much more economical, and card friends who know a little technology even solve it themselves.
However, the roadside maintenance shop water is also very deep, not to mention the technical maturity, the quality of accessories can not be guaranteed, there may also be substitution repairs, false maintenance items, maintenance list fraud, spare parts to shoddy and other unscrupulous behavior, these are the lessons learned by people who have come.
Either it was fixed and it didn't take long to break down again; or the money was too much and the car hadn't been fixed. If you have to repair it in a small shop, it is recommended that card friends find a familiar and trustworthy shop.
Use a traditional water dispenser
Whether the water sprinkler is good or the hydraulic retarder is good, it has always been a controversy in the circle, some think that the water sprinkler is low in cost, the effect is remarkable, and can meet the daily water demand; some think that the liquid is light and light, the technology is more secure, and the wear of vehicle parts can be reduced.
With more and more examples of accidents caused by downhill brake failures, liquid slowness has also been recognized by more and more people, although many of them still insist on using traditional water sprinklers. It is not that these card friends put safety aside, on the contrary, the price of liquid slowness is really not very friendly to card friends.
It is reported that the original price of liquid slow is about 20,000-30,000, and the price will be higher if it is installed in the later stage, which is also the biggest resistance to the popularization of liquid ease. In fact, if you really want to investigate deeply, the water sprinkler is not necessarily cheaper than the liquid slow, because in addition to the purchase of the previous purchase and the addition of the water tank, the water fee is not a small amount in the long run.
It is recommended that card friends who often run long downhill sections should still install liquid slowness on the car, give themselves more protection, and give their families more peace of mind.
Editor's Note
I don't know if you have found that behind these little clever people have a common purpose - to save money. Truck three points rely on maintenance and seven points rely on maintenance, according to statistics, a truck needs an average of about 30,000 maintenance costs per year. Just as the so-called driving money to the car to spend, there is no money to take home, do not want to save some how to do.
In the end, it is because the freight market is too depressed now, and if the income is considerable, truck drivers are not willing to do this kind of thing because of small losses. (Text/Maggie Cheung)
