Misunderstanding 1: lubricating oil often needs to be replaced
It is correct to check the automobile lubricating oil frequently, but only replenishing without replacing can only make up for the shortage of oil quantity, but cannot completely compensate for the loss of lubricating oil performance. During the use of lubricating oil, the quality will gradually decline due to pollution, oxidation and other reasons. At the same time, there will be some consumption, reducing the quantity.
Misunderstanding 2: additives are of great use
High quality lubricating oil is a finished product with a variety of engine protection functions. The formula already contains a variety of additives, including anti-wear agents. Moreover, the lubricating oil pays more attention to the balance of the formula to ensure the full play of various performances. Self adding other additives will not bring additional protection to the vehicle, but will easily react with the chemicals in the engine oil, resulting in the decline of the comprehensive performance of the engine oil.
Misunderstanding 3: When the lubricating oil turns black, it's time to change it
This understanding is not complete. For the lubricating oil without detergent dispersant, blackening is indeed a sign of serious deterioration of the oil, but the lubricating oil used in modern cars is generally added with detergent dispersant. This tranquilizer washes the adhesive film and black carbon deposit on the piston and disperses them in the oil to reduce the generation of high-temperature deposits in the engine. Therefore, the color of the lubricating oil tends to turn black after a period of use, but the oil is not completely deteriorated at this time.
Mistake 4: Add as much lubricant as you can
The amount of lubricating oil should be controlled between the upper and lower scale marks of the oil dipstick. Because too much lubricating oil will rush into the combustion chamber from the clearance between the cylinder and the piston to form carbon deposits. These deposits will increase the compression ratio of the engine and increase the tendency to produce detonation; The carbon deposit in the cylinder is red hot, which is also easy to cause early combustion. If it falls into the cylinder, it will aggravate the wear of the cylinder and piston, and also accelerate the pollution of lubricating oil. Secondly, excessive lubricating oil increases the stirring resistance of the crankshaft connecting rod, which increases fuel consumption.
