1. Clean the water tank regularly. Rust and scale will limit the flow of coolant in the cooling system, reduce heat dissipation, lead to overheating of the engine, and even cause engine damage. So it is necessary to clean the tank regularly to remove rust and scale.

2. Replace oil and filter element regularly. Any quality grade of lubricating oil in the process of use will change the oil quality, in order to avoid the occurrence of failure, should be combined with the use of conditions for regular oil change, and make the amount of oil moderate to the upper limit of the oil ruler is good).

3. Keep the crankcase well ventilated. Now most gasoline engines are equipped with PCV valve crankcase forced ventilation device), but the pollutants in the channeling gas will be deposited around the PCV valve, may make the valve blocked. Therefore, it is necessary to regularly remove pollutants around the PCV valve.

4. Use lubricating oil of appropriate quality grade. For gasoline engine, SD-SF gasoline oil should be selected according to the additional device and service conditions of the intake and exhaust system; The diesel engine should choose CB-CD diesel engine oil according to the mechanical load, and the selection standard is not lower than the requirements specified by the manufacturer.

5. Clean the fuel system regularly. Regular cleaning of the fuel system to control the formation of carbon deposits can keep the engine in the best condition.

6, maintenance of filter. Three filters refers to air filter, oil filter and gasoline filter. Three filters play a role in filtering the air, oil and gasoline on the automobile engine, thereby protecting the engine and improving the efficiency of the engine.

7. Clean the crankcase regularly. During the operation of the engine, the high pressure unburned gas, acid, moisture, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, and the metal powder produced by the wear of the parts is mixed together to form sludge. Therefore, the crankcase should be cleaned regularly to keep the engine clean.

The above is some knowledge to extend the life of the car, now private cars have no specific mandatory scrap years, as long as the annual inspection can pass can continue to drive, so you have to take good care of their own car oh.
