Do you know some common sense of engine oil maintenance?

Of course, the most important part of vehicle maintenance is engine care, and the most important way to maintain the engine is to make it get the most effective lubrication. Proper use of engine oil can prolong the life of the engine and save fuel. Otherwise, it will be counterproductive. The car owner had better form the habit of checking the oil every week, and take the remaining oil for oil change and maintenance on the car, so as to be prepared.
Some misunderstandings in selecting engine oil
1. Some car owners mistakenly think that a certain brand of engine oil is the special engine oil for a certain brand of automobile when selecting engine oil. In fact, this is wrong. As long as the grade and viscosity requirements meet the requirements of your car, you can buy it.
2. Use additives at will. The engine oil itself is made up of base oil and additives, so as long as the car owners use high-quality oil, they don't need to add any other additives.
3. The more expensive the oil is, the better. The selection of oil should be based on the requirements of the engine. There is no need to use too high-grade oil on the engine with lower requirements, nor can the lower level oil be used on the engine with higher requirements.
4. It's not that the more you add, the better. Too little oil will cause the parts to burn out and accelerate the deterioration of oil. However, if the oil level is too high, it will rush into the combustion chamber from the gap between the cylinder and piston, which will increase the carbon deposition in the combustion chamber.
Method / step
1. How to select the engine oil? The owner must know the temperature and environment of the vehicle when selecting the engine oil, and then purchase the engine oil according to the oil grade and viscosity requirements specified in the vehicle manual. When purchasing, carefully check the grade and viscosity label on the oil package, and select the oil that meets the requirements of the lowest level or above. For example, in Sichuan area, under normal circumstances, the use of multi-level viscosity standard SAE15W-40 oil can be. But Chongqing area is hotter in summer, it is better to choose oil with viscosity of 50. The first few thousand kilometers of the new car is called the running in period. In this stage, the tiny protuberances on the parts will be worn off, so that the fit clearance of each moving part is closer and the movement is smoother. At this time, the selection of oil is more important. In the running in period, oil with viscosity grade of 15W / 40 or 40 is generally selected for running in. Due to the uneven or tight fit clearance of each component after a new car or engine overhaul, it is necessary to run in and adjust it during the running in period. If the oil with larger viscosity is selected, it is not easy to form lubricating oil film on the surface of friction pair with poor matching clearance, which will cause dry friction, resulting in excessive wear, and even mechanical failures such as Bush burning and shaft holding. The oil with lower viscosity can achieve better cleaning and cooling effect due to its better fluidity. If you use a car in the city, because of frequent traffic jams, it is a loss type driving, it is recommended to shorten the mileage of oil change.
2. Don't forget to pack the oil when changing the engine oil. You should do routine maintenance every certain kilometer. Change the oil and three filters. However, each time the oil is changed in a bucket, there will be a little surplus after the oil change.
Don't forget to pack the remaining oil for later use. In this way, when it is found that the level of oil and liquid drops after one or two months and it is necessary to replenish it, the owner can also "rinse" the engine with the accumulated oil from several times of maintenance before a certain oil change to make the oil change more thorough
Do not mix engine oil
Sometimes you find that the oil level of your car is insufficient and you need to add oil. At this time, you must pay attention not to add oil of different brands or models. According to the researchers, the additives used in different brands of oil products will be different, and mixed use may cause deterioration of oil products.
