What kind of gasoline should be added in a car，Eating coarse grains or fine food is clearly written on our car's instructions，But I know，There are very few people who really read that manual，It is estimated that when the manufacturer designed the car, I also know that everyone rarely goes through，So labeled this information on the fuel tank cover。

Different engines of each car，The method of doing work is different，Therefore, the demand for fuel is different，So the manufacturers before the factory have clear regulations，Add error oil has a great impact on the car engine。If a car is added with too high label gasoline, it is okay to say，At Seabetbest, it only cost more money;But if a high -marked fuel engine is used with low label fuel，That is to say, if luxury cars eat coarse food，It may lead to insufficient fuel in our car，generate a certain amount of carbon deposits，to make the car jitter obvious。

Objectively，On the basis of oil products，Generally, the combustion value of the high label gasoline is even better，It can make the fuel fully burn，to achieve the purpose of fuel saving;And high -marked gasoline contains lower sulfur content，Not only can the environment be protected，It is not easy to produce oil dirt，At the same time, it will avoid body jitter。It can be seen that it is necessary to add gasoline with the label.For example, the manufacturer recommends that your car is plus 92 gasoline，The label of the fuel tank cover will be indicated:Gasoline with labeled No. 92 and above，It can effectively avoid the error oil that the car employees can give us wrong oil.。

There is another detail that is not noticed by many friends，That is the air pressure value of the tire，Its air pressure is suitable and not suitable for the performance of the entire vehicle。For example, the load capacity of the car、Dynamic、smoothness、Through sex、smoothness、How much is the life and fuel consumption of tires，All are closely related to the pneumatic pressure of the tire。

Most of the car's fuel tank cover will also indicate the air pressure value that the tire should use at different loads of the car。Of course，Changing with temperature，The air pressure value must also be adjusted，It is necessary to keep the vehicle under a suitable air pressure condition。

Tire's air pressure is too low，The contact area of ​​the tire and the ground will be too large，thus leading to seabet ioa larger friction with the ground。Not only does the tire losses large, but also increases fuel consumption.If the tire pressure of the tire is too high，Especially under the conditions of hot weather，We can imagine that the tire is a plump balloon，There is a little squeeze in the outside world，or bump，Balloon will explode。Similarly，Although the tire will not be so fragile，But there are still great hidden dangers for our driving safety。So，Knowing our car tire pressure is very important for our travel，Many tire pressure monitoring devices on the car，At this time, we can refer to the value on the fuel tank cover，It is very important to keep it in a reasonable range。

In addition to the labeling on the information，There will be one on the cover of the fuel tank，That is the drainage hole。There are many drainage holes on the car, for example:Drainage holes in the sunroof、Drainage holes under the door panel、Trunctarial drainage holes、cabin drainage holes and air conditioning drainage holes。Other drainage holes are well understood，For example, it can be drained very well when it rains，So why is there a drainage hole here?

In fact, its role is the same as its surface meaning，It is used to discharge liquid matter。After all, there is still a gap in the fuel tank cap，Some friends may also staggered the fuel tank cover inadvertently。Including the time of car washing，When rushing with water, it will inevitably not enter the water from the gap，Plus everyone may have gasoline splash when cheering，Will gather at the position of the fuel tank entrance。At this time, the importance of drainage holes appears，The role of his existence here is to discharge these water or residual liquids in time in time。If there is a stagnant water，It seabet myis very likely to enter the gasoline tank，In this way, it will cause certain damage to our engine。Of course, we must pay attention to cleaning up this drainage hole，Never let this small hole be blocked。
