Develop good driving habits and check the oil level regularly. A high oil level will not only increase the resistance of the engine during operation, causing unnecessary power loss, but also cause oil leakage; a low oil level will damage the engine due to poor lubrication. Therefore, if the engine oil level is too low, check whether the engine has oil leakage and abnormal oil consumption; turn on the ignition switch before starting the engine, and the oil level indicator and oil pressure indicator light up, and they should go out after starting the engine.
Use oil with appropriate viscosity. If the oil viscosity is too low, the oil film is easily damaged and parts are stuck; if the viscosity is too high, additional resistance to the movement of parts will be generated, making it difficult to start the engine and increasing power loss. Therefore, when changing the oil, refer to the viscosity recommended by the manufacturer in the driver's manual as much as possible.
(1) Select oil according to the climate
When the ambient temperature is low, select oil with a lower viscosity to facilitate engine starting. When the ambient temperature is high, choose an oil with a higher viscosity to facilitate movement and maintain the oil film;
(2) Choose the oil according to the vehicle condition
For engines in good condition, the clearance is small, so an oil with a lower viscosity can be used. For engines in poor condition, the clearance is large, so an oil with a higher viscosity can be used;
(3) Use special oil
Due to the high combustion pressure of diesel engines and the sulfur-containing diesel produces sulfurous acid diluent oil after combustion, diesel engines should use special oil for diesel engines that can neutralize sulfurous acid.
(4) Reasonable use of automobile engine maintenance products
Enhance the lubrication performance of the engine, avoid engine wear, and replace repair with maintenance.
Regularly change the engine oil, use high-quality engine maintenance products for maintenance, regularly clean the sludge, colloid and carbon deposits inside the engine lubrication system, keep the lubrication system clean, and use engine protection products to effectively improve the lubrication performance of each component, reduce wear, and increase the service life of the components.
For the automobile engine lubrication system, as long as regular maintenance is done, it can not only extend the service life of the engine, but also reduce unnecessary economic losses.
(5) Cleaning the oil channel
The cleaning method is: after the waste oil is drained, inject thin oil or filtered high-quality diesel into the engine oil pan, the amount of which is equivalent to 60%-70% of the standard oil level capacity of the oil pan, then run the engine at idle speed for 2-3 minutes, and then drain the washing oil.
