| Four major errors in the use of lubricating oil |
| Time:2016-5-21 |
Automotive lubricants in the maintenance of the frequency of use is very high. High quality lubricating oil in addition to engine protection, reduce the number of oil, but also can save the cost of gasoline. Also note that don't use undeserved cause for lubricating oil vehicle failure, improper use in general, source to riders of lubricating oil four "misunderstanding".
For the following four kinds of misunderstanding, the relevant technical personnel to give a professional explanation:
Misunderstanding one: oil is often added to change
Often check the lubricating oil is correct, but only add to make up for the lack of oil, but can not completely compensate for the loss of performance of the lubricating oil. In the process of using, because of pollution, oxidation and other reasons, the quality will gradually decline, and there will be a number of consumption, so that the number of.
Misunderstanding two: the use of large additives
The real quality of lubricating oil with a variety of engine protection function of the finished product, the formulation already contain a variety of additives, including antiwear agent and lubricant most is fastidious about the balanced formula to ensure the full play of the various performance. Adding other additives not only can not bring extra protection to the vehicle, but it is easy to react with the chemical substances in the oil, resulting in a decline in the overall performance of the oil.
Myth three: what time should the lubricating oil black oil change
This kind of understanding is not comprehensive. For the addition of the quiet dispersion of the lubricating oil, the color black is indeed a serious deterioration of the performance of the oil, but the use of modern cars are generally add a quiet oil. This quiet agent will adhesion on the piston glue film and black carbon washing down, and dispersed in the oil, reduce the formation of sediment in the engine high temperature, so the lubricating oil using a period of time after color to black, but when the oil did not completely deteriorated.
Misunderstanding four: lubricating oil can add more on
The amount of lubricating oil should be controlled between the upper and lower marks of the oil gauge. Because too much oil from the gap between the piston and cylinder in fleeing into the combustion chamber to form coke. These carbon will improve the engine compression ratio, increase the knock tendency; coke in the cylinder was glowing red also easily lead to premature combustion, such as falling into cylinder exacerbate the cylinder and piston wear, but also accelerate the oil pollution. Secondly, the lubricating oil is too much to increase the friction of the crankshaft connecting rod, so that the fuel consumption increases. |
