Automobile maintenance knowledge

The maintenance of a vehicle depends on two indicators of the vehicle, the number of kilometers and the year. When the vehicle is used for different kilometers and years, the items that need maintenance are also different. Give examples of some common maintenance projects:

Engine oil and machine filter:

Engine oil and machine filter generally need to be replaced at every maintenance.

The oil change time and kilometers depend on the type of oil used and the driving conditions of the vehicle.

Synthetic engine oil is generally replaced every 10000 km or 1 year.

Semi-synthetic engine oil is usually replaced every 7,500 kilometers or half a year.

Mineral engine oil is usually changed every 5,000 kilometers or 3 months.

Mechanical filters are usually replaced by oil.

If the road is very congested, it is recommended to replace the vehicle 1000 km and 1 month in advance.

Engine air filters are generally replaced every 20,000 kilometers or so.

Filtration of dirty air in the engine will lead to dirty air entering the engine, and the mixed concentration of gasoline will be reduced, resulting in insufficient combustion of mixed gas and excessive carbon accumulation in the cylinder, which will affect the fuel consumption and power of the vehicle.

There are two types of engine fuel filters:

The built-in ones are generally replaced once every 10W km.

External ones are generally replaced every 20 thousand kilometers or so.

If the fuel quality in the use area is not very good, it is recommended to replace it in advance.

Too dirty fuel filter will cause too dirty fuel to enter the engine for combustion, and the carbon deposit in the engine will form faster, the fuel consumption will increase and the power will be insufficient, so it is necessary to replace the fuel filter regularly.
