The most common mistake! An NG habit when refueling a car may not think it will cause you to hurt your pocket

An error and bad habit while refueling a car may cause you to lose hundreds of dollars.

A car mechanic posted a video on TikTok, sharing the most common mistakes that many people make when entering gas stations, which is that they are filling up too much.

The account is @sweet_tea, and a mechanical engineer from Texas pointed out that being too full of fuel may cause problems with the purge valve. The exhaust valve is a component used to adjust the engine fuel flow. Its main function is to stabilize the pushing pressure of the gear pressure increase system to protect the engine and gear pressure increaser.

When a car starts, the exhaust valve should be closed, and if this valve is damaged, it will become a state of opening. This is not a big problem most of the time, but after refueling, the oil gun rushes to generate excessive amounts of oil. If there is no valve blockage, the oil will fill the cylinder. When the gasoline/air ratio is too high, there will be no enough oxygen and the car will not get hot.

The mechanic said in the video that when the fuel tank is too full, the exhaust valve will cause the car's "check engine" light to light up. If you continue to refuel too much, you will eventually have to change the exhaust valve, which may cost more than $500 to change one.

The mechanic said that the reason why he posted this video was that when he was refueling, he saw someone next to him who was full of gas and the car made only noise and could not fire. This was the case with many attempts.

Then he explained this truth to the other party, and said that it would cost at least hundreds of yuan to change the air-relieving valve, etc. However, while the other party ignored it, he even directly accused him of just taking care of his own affairs and not taking care of it too much.

The mechanic said in the comment area, "I tried to be a little friendly, and then walked over and said to him, "Hey, it's not good to fill your fuel tank." He immediately responded, "Why do you care about your own business?" "The mechanic said that he actually just wanted to help the other party avoid damaging the gas valve, but unfortunately "good intentions have no good report" and caused humiliation.

According to J.D. Power Research's research, filling up the tank will cause blockage of exhaust valves, and changing one may cost between $100 and $500.

The camera has posted more than 2.1 million views, and a large number of comments have been included in the review area, mostly praise his suggestions, thanks for sharing his experience, and hopes that he can make more videos of this suggestion.
