As we know, it has a high frequency of using the lubricating oil when your car was maintained. And the lubricating oil with high quality can not only protect the engine, reduce the times to change the oil, but also save more money spent on gasoline. In viewing of it, for many car owners especially the new users, they tend to think that when the color of the lubricating oil has become black, it is time to change it. So is it true? If you are not sure, we suggest you first surf on the internet and find out some information on the related Automobile Diagnostic Website to have a better knowledge of the common sense of the auto.
Well, improper use of the lubricating oil is sure to cause the car trouble, so what is the error using of it? The "inappropriate" using methods generally comes from four "misunderstanding" for the lubricating oil by the car owners.
For the following four "misunderstanding", the relevant technical staff has given the professional explanation:
Error 1: Often added, but never changed
It is correct for always checking the lubricating oil. However, just supply it but never replace, it can only compensate for the lack of quantity, and can not fully compensate for the property loss of the lubricating oil. During the use of the oil, the quality will be generally decreased because of the contamination, oxidation and other reasons. Meanwhile, there will be some consumption, and the number will be reduced.
Error 2: Large function for the additive
The real high quality lubricating oil is the final goods with a variety of motor protecting function. Many additives have been contained in the formula, including the anti-wear agent. And as to the lubricating oil, the most important is to keep a balance of the recipe to make sure a full playing of all kinds of the performance. If you add other additives to your car by yourself, it will not bring the additional protection to your vehicle. Instead, it will be much easier to react with the chemicals in the oil, and cause the comprehensive performance of the oil decreased.
Error 3: When becoming black, it's time to change the lubricating oil
This is not a comprehensive understanding. For the lubricating oil without cleaning dispersant, the black color of the oil is really the mark of seriously deteriorated oil. However, the lubricating oil that used in the modern automobiles are generally added with the quiet dispersant, which will wash the coating adhered to the piston and the black carbon deposit, and then disperse them in the oil, so that it will reduce the generation of high temperature sediment of the engine. Therefore, after a period of time of using, the lubricating oil will become black, but it doesn’t mean it has been gone bad completely.
Error 4: The more the better
It is better to control the amount of the lubricating oil between the upper and lower scale line of the oil level gauge. Because too much oil jumped into the combustion chamber from the gap of the cylinder and piston and burning into carbon deposit, which will increase the compression ratio of the engine, and increase the tendency of producing detonation. Moreover, the carbon deposit within the cylinder once showed in the red state, it is much easier to cause preignition, and if dropped off the cylinder, it will accelerate the abrasion of the cylinders and pistons, as well as speed up polluting the lubricating oil. Secondly, too much lubricating oil has also added the stirring resistance of the crankshaft connecting rod, as a result, it will make the fuel consumption increased.
So have you completely understood the nature of the black color of the lubricating oil? If still not and bothered by many other malfunction for the daily use of your car, maybe you should go for a online auto repairing store and try a new Auto Diagnostic Tool, such as Launch X431 Diagun III Auto Scanner, Launch X431 IV GX4 Master and the Autel MaxiSys MS908 Automotive Diagnostic tool, etc for a full checking for your car and then you will be much easier to find out where the problem is. Only under which can you suit the remedy to the case.
