In the maintenance of the car when the frequency of use is relatively high than oil. In addition to saving gasoline expenses and reducing the number of oil changes, high-quality lubricants can also protect the engine. However, riders often have misunderstandings about lubricants, causing automobile breakdowns caused by improper use of lubricants. Misconception 1: Lubricants can be added more The more lubricating oil is not better, the amount of oil should be controlled between the upper and lower scale lines of the oil dipstick. Too much on the one hand will increase the stirring resistance of the crankshaft connecting rod and increase the fuel consumption. On the other hand, too much lubricating oil will enter the combustion chamber from the gap between the cylinder and the piston and burn to form carbon deposits. These coke deposits will increase the engine compression ratio and increase the tendency to produce knocking. Coking in a red hot state in the cylinder will also cause premature combustion. If it falls into the cylinder, it will increase the wear of the cylinder and the piston, and it will also accelerate the pollution of the lubricant. Misunderstanding 2: When the lubricant becomes dark, it is time to change the oil. This understanding is one-sided. For lubricating oils that do not add a clear dispersant, the darkening of the color is indeed a sign that the oil has been seriously deteriorated, but some automotive lubricants are generally added with a decomposing agent. This clearing agent cleans the film and black coke adhering to the piston and disperses it in the oil to reduce the formation of high-temperature deposits in the engine. Therefore, the lubricant is used. After a period of time, the color tends to darken, but at this time the oil does not completely deteriorate. Misunderstanding 3: Lubricants often add no change Regular inspection of the lubricant is correct, but adding only to it can only compensate for the lack of oil, but it cannot fully compensate for the loss of lubricant performance. During the use of lubricating oil, the quality of the lubricating oil will gradually decrease due to pollution, oxidation, etc. At the same time, there will be some consumption and the quantity will decrease. Misunderstanding 4: Large use of additives Some owners will have a habit of adding additives themselves. This is not a good thing. This practice not only does not bring additional protection to the vehicle, but it also tends to react with the chemical substances in the engine oil, resulting in a decline in the overall performance of the engine oil. A truly high-quality lubricant is a finished product with a variety of engine protection functions. Formulations already contain a variety of additives, including anti-wear agents, and lubricants are the most balanced formulas to ensure full performance of all kinds of performance.
