General knowledge of automobile maintenance High grade gasoline is not suitable for all models


How can we better drive the car and what should we pay attention to while using the car? Xiao Bian has specially arranged relevant automobile maintenance and beauty knowledge, hoping to help owners!

Air conditioning and maintenance should pay attention

A lot of my friends' cars are relatively old, they always feel that they have taste in the car, but they usually have a hard time to clean. When the sky is hot, they don't feel much like they open the window, and they are always cold and allergic to the nose. In fact, the air-conditioner condenser is stained with a lot of sediment. After a long time, the condenser will be rusted and the service life of the air conditioner will be shortened. Therefore, it is very important to make maintenance for your car's air-conditioning.

Bumpy roads do not open the skylight

It is best not to fully open the skylight on bumpy roads, or the related parts may be deformed due to the excessive vibration between the sunroof and the slide rails. Second, the partition must be opened before opening the sunroof to prevent the sunroof motor from being overloaded and causing a malfunction.

Finally, in the season of heavy sandstorm, it is better to clean the skylight track every month to avoid accumulation of excessive sand in the track, increase friction, and wear parts.

High-grade gasoline is not suitable for all models

Many people are keen to use high-grade gasoline and even consider the label as the standard of fuel purity and quality.

In fact, the gasoline number only indicates the octane number of gasoline, that is, the antiknock property, and it has nothing to do with the purity and quality. The No. 97 oil, which is used as the No. 93 oil engine, will have a phenomenon of “delayed combustion”, that is, it will not reach the point of self-ignition until it reaches the head. The combustion is incomplete, causing pollution and waste.

Oil adjustment can reduce fuel consumption

Many people like to enjoy the sensation of boosting fuel, but do not know that this is at the expense of increasing fuel consumption, and the increase in fuel consumption does not increase the number of kilometers traveled by the vehicle. Therefore, in order to save energy, ask the owner to drive at a constant speed. When accelerating, please slowly add fuel. Also, please try to avoid using brakes to adjust the speed and use oil to adjust.

Clean engine cooling system before adding antifreeze

The owner must clean the engine cooling system before adding antifreeze. The descaler and cleaning agent are included in the antifreeze. If the engine cooling system is not cleaned before use, the tank should be soaked with a 10% caustic soda solution for one hour. Then, the flushing liquid is discharged, and then repeatedly washed with demineralized water 2 or 3 times to remove the original accumulated scale in the engine cooling system. After the flushing, the antifreeze liquid can be filled.
