Annex: need for maintenance:
As the age and mileage increase, the technical condition of any vehicle deteriorates: the body of the car loses the light of the past, the fixed parts become loose, the co-operation gap between the various sections increases by wear and tear, and the various vehicle protection fluids, such as oil, gear transformer oil, cooler fluids, are corroded, muddled, spoiled and disabled, which, like human blood, directly provide the various parts of the vehicle。
Basic orientation of vehicle maintenance:

1. Body maintenance. Car maintenance is also called car beauty. The main objective is to remove all oxidation and corrosion from the outside and inside of the vehicle and then protect it. These include, inter alia, painting maintenance, carpet maintenance on cushions, maintenance of bumpers and skirts, maintenance of dashboards, maintenance of electroplating processing, preservation of leather plastics, maintenance of tyres and wheelbarrows, maintenance of windshields, maintenance of chassis, maintenance of motor appearance, etc。
2. Indoor maintenance. In order to ensure that cars are in the most appropriate technical condition. This includes, inter alia, the maintenance of lubricating systems, fuel systems, cooling systems, brake systems, and petrochemicals (fuel nozzles)。
3. Refurbishment of body. Examples include the diagnosis and treatment of deep scratches, the repair of multi-material safety poles, the repair of hard-on-wheel (shield) damage, the refurbishment of leather and fibre-optic materials, and the renovation of engine colours。
After 60,000 kilometres of domestic vehicles, major maintenance is required if no major maintenance was previously available. After 60,000 km, there is a need to replace spark plugs, oil, oil filter cores, petrol filter cores, empty air filter cores, empty adjusted filters, belts, brake blades, cooling fluids, brake oil, etc. If excessive maintenance has previously been done, only routine maintenance is required after 60,000 kilometres。
Car maintenance is not that complicated. The vehicle was maintained only for the replacement of oil and tangible items。
The oil included oil from the vehicle, cooling fluids, brake oil, gear tank oil, diversion oil, etc。

Visible items on the car include rainbrushes, belts, various filters, brake blades, brake plates, tyres, spark plugs, fuses, etc。
Maintenance was performed by replacing vulnerable items and oil and by inspecting other parts of the vehicle。
Brake oil can easily be ignored by many carmates. Brake oil is an easy liquid to suck. It is recommended that the companion check the amount of water contained in the brake oil while maintaining it。
If the brake oil is up to 3 per cent, it will need to be replaced immediately, otherwise the power will be reduced and the brake distance extended。
When the brake oil is replaced, a professional shop or a 4s shop needs to be replaced. The carmate is not advised to replace the brake oil himself。
