Now our high-speed transportation network is more and more developed, like the north, Guangzhou, and Shenzhen, it is very likely that every time we go out, we have to run on the urban expressway or highway for a while. However, many times, because we are too busy, the inspection of the safety aspects of the car is still not in place, and I understand that many friends see that every one or two months, we occasionally look at whether the tire pressure is too low, whether there is a nail and the depth of the tire pattern is enough to be more "superficial" things.
And many of the details that are hidden deeply and seriously affect driving safety have been ignored. Understand brother today to take you to know, those old drivers are easy to ignore the details of the impact on safety. Check your car after you learn it!
The tire wall is scratched
Many friends know to check tires, but only check the tire pressure and the tread is stuck in the nails, which are obvious. What many people don't know is that the tire wall is the thinnest and most vulnerable part of the entire tire, and the damage to the tire wall is not easy to find, but it will seriously affect driving safety. The most likely situation to cause scratches on the tire wall is in our daily life, it is inevitable to park on the side of the road, and occasionally ride on the road teeth.
If you do not pay attention, the side tire rubs into the road tooth, the tire wall is "cut" by the road tooth like a knife, cutting off a piece of skin from the already thin tire wall, which is very easy to hurt the tire cord layer, and soon the tire wall will form a bulge. There is also a situation, driving on the road surface with poor road conditions, the tire wall on the inside of the tire is easy to be cut by sharp stones, and it is difficult to check the situation on the inside of the tire during daily inspection, which is easy to be ignored.
Therefore, I understand that friends suggest that if you often do the "dangerous action" that is easy to cause harm to the tire wall when you use the car in daily life, or often drive on the road surface with poor road conditions, you must often check the tire wall, once you find that the tire wall is damaged or bulging, please do not risk the risk of bursting the tire at any time, repair the tire wall or ignore it, the car is very easy to burst the tire when driving! So when the tire wall is damaged, be sure to replace the tire in time!
Oil
Engine oil can be regarded as the "blood of the car", mainly responsible for the internal heat dissipation, lubrication and cleaning of the car engine. The use of oil has a lot of places to pay attention to, like we usually care most about the amount of oil, the oil ruler pulled out to observe can know whether there is too much or too little oil, this is the most basic aspect. In fact, the oil is not only the right amount to use, but also refer to the car's instruction manual, use the appropriate viscosity, quality grade and confirm whether it is genuine oil.
Brother understand some friends, in the purchase of oil only choose the expensive not to choose the right, for example, the car requires the use of the original label of 0w-20 viscosity of the oil, and he feels that the use of a higher viscosity of the oil on the engine protection will be better, and chose the well-known big brand of 15w-40 higher viscosity oil. The use of high-grade oil increases the internal resistance of the engine when it is running. Cause increased noise, increased fuel consumption or is a small matter, if you use high-grade oil for a long time, it is easier to cause the engine's heat dissipation efficiency to become worse, the cleaning effect is reduced, and the damage to the oil pressure pump is huge, over time, it is easy to let the engine enter the old age in advance.
The worst thing is the fake oil. If the oil that does not meet the requirements of the manufacturer is added, at most it is a "chronic disease" that shortens the life of the engine and makes the economy worse. The fake engine oil is the "arsenic" of the engine, and in the face of inferior fake oil, it is likely that it only needs to be recruited once, and the engine will be overhauled or even scrapped. Therefore, for the sake of the car, I understand that my brother recommends that friends try not to covet cheap, buy oil in unknown channels, or buy some brands of oil that have never heard of it.
Wiper
When we use cars in daily life, the frequency of wiper use is low, and if our car is often parked in the open air, the wiper is exposed to the sun's rays, high temperature and ultraviolet rays will make the rubber of the wiper deteriorate, plus sand, leaves, dust and other debris stained on the wiper, it is easy to cause damage to the wiper blade. When it rains, it is found that when the wiper moves, a small water droplet is generated on the windshield, or several water marks, which seriously affects the line of sight. Especially at night, the small water droplets will become a "convex lens", the light in front of the light through the small water droplets after focusing in the eyes, just like a small light bulb attached to the windshield, will have a blinding effect on the driver, seriously affecting safety!
Is there any way to extend the life of a wiper? Yes, understand the brother to teach everyone two points:
Try to park your car in the underground parking lot, not only to avoid the high temperature of the sun, but also to eliminate the invasion of leaves, dust, and bird droppings.
When driving safely, occasionally spray water to scrape to keep the wiper clean between the wiper and the glass. Otherwise, wait until the dust, gravel, garbage, etc. on the top are piled up, and then move the wiper, the damage of the wiper blade is a small matter, and the front windshield is hung scratched one by one, and it will be painful to think about.
If the wiper can no longer guarantee a clear field of vision, brother understands that friends should replace the wiper in time. After all, two wipers are only a few dozen dollars, and the value is not high, but it will seriously affect driving safety.
Write to the end
These are some details that Brother Understand found in his daily use of cars that are easy to be ignored by everyone and are very harmful. If netizens also have some discoveries in safety when using cars in daily life, welcome to leave a message and communicate with brothers, share with more netizens, and enrich our car knowledge together!
