Five oils
　　Motor oil, transmission fluid (gear oil), brake fluid, steering fluid and petrol; three water: antifreeze, glass water and battery water.
　　Motor oil
　　All known as engine lubricant, the main role of the oil is in the engine running, in the engine needs to lubricate the position of the flow, to reduce wear and tear between the engine parts, to extend the service life of the engine.
　　Spark Plug
　　Spark plugs introduce high voltage current from the battery into the cylinders, creating an electric spark that ignites the gas mixture in the cylinders, thus starting the cylinders and starting the engine. Each cylinder must be equipped with at least one spark plug, and some models are equipped with two spark plugs per cylinder.
　　Oil Filter
　　The oil filter element serves to filter out debris, gums, and water from the oil, providing a guarantee of the oil's quality. It is replaced along with the oil when the oil is changed.
　　Poor quality cartridges meet the following characteristics
　　1) The font on the filter surface is blurred or not clear enough, and the printed paint surface is inferior and thin.
　　2) There is no bypass valve. Once the filter becomes clogged, the engine will not receive sufficient oil lubrication.
　　3) There is no function to inhibit oil return when the engine is switched off, and engine wear will be greater during cold starts. All genuine filters have a sophisticated oil return inhibition design to ensure that the filter contains the necessary oil for the next start-up, reducing wear during cold start-up.
　　4) Poor sealing material of the gasket may cause oil leakage under high temperature and pressure, and even lead to fire.
　　(5) The filter paper is made of different materials, making it difficult to achieve the intended filtration effect.
　　6）Metal oil filter mesh is rough, it is difficult to ensure the oil volume is abundant.
　　Air filter element
　　The role of the air filter element is to filter the dust suspended in the air when the engine is working to ensure clean air intake. The air filter on the car is mostly made of paper, and the replacement cycle is about 10,000 kilometres, and the specific replacement is based on the use of the environment and the use of the situation.
　　Air conditioning filter
　　The role of the air conditioning filter is to filter the dust and pollen into the air conditioning system when the air conditioning is turned on, to ensure that the evaporator box, the air inside the car is clean.
　　Petrol Filter
　　Filter out impurities in the fuel, so that the mixture into the cylinder and then cleaner, both to protect the engine and make the emissions more environmentally friendly, divided into built-in type and external type.
　　Steering oil
　　The role is to make the steering wheel steering effort easier through hydraulic action when the owner is turning the steering wheel.
　　Glass water
　　This one is known to everyone and is used to clean the front and rear windscreen or headlights. Glass water is divided into two kinds of winter and summer glass water, winter according to the local temperature using the lower freezing point of the glass water, summer glass water is mostly for cleaning the role of glue removal.
　　Brake fluid
　　Brake fluid, also known as brake booster fluid, is the medium for transmitting braking pressure in the braking system. When you step on the brake, the brake fluid generates hydraulic pressure, which pushes the air to make the brake pads and discs friction braking, and at the same time, it plays the role of cooling down the temperature.
　　Wipers
　　With glass water, you will inevitably need wipers to clean the front and rear glass. Wipers need to be replaced when they fail to scrape clean, and the replacement cycle is about 1 year.
　　Battery
　　Also known as the battery, the role of the car is not started when the car power supply, the car is mostly maintenance-free batteries, replacement cycle in 2-3 years, the price of 300-1000 yuan range.
　　Brake pads
　　Brake pads, also known as brake linings, are the actuating parts of the braking system. Brake pads directly affect the performance of the brakes. When the brake pedal is pressed, the brake pads will be squeezed on the brake disc or drum to stop the wheel from rotating. Different driving habits can make a huge difference in the wear and tear of the brake pads, and it is recommended that they be checked and replaced in a timely manner.
　　Transmission Fluid
　　Transmission fluid is the oil used to keep the shifting system clean, which ensures that the transmission works properly and prolongs the life of the drive train.
　　Antifreeze
　　Antifreeze is also known as coolant, and as the name suggests, its main purpose is to prevent freezing and dissipate heat from the engine. Of course, antifreeze is not the same as water, and the substances incorporated in it can play a role in preventing corrosion and scale.
　　Clutch plate
　　Role is to transfer power to the transmission, the clutch plate generally do not need to be replaced, when there is an acceleration when the speed of the car is higher than usual, smell the smell of burning, shaking, gear difficulty should be checked and replaced.
