As the "blood" of the car, the importance of the oil to the car is self-evident, it is mainly for the engine of the car to lubricate, seal, cool, anti-rust, buffer and other effects. It is precisely because oil has so many effects on cars, so old drivers also attach great importance to the choice of oil products, and even some brands of cars have lost a large number of potential customers because of the phenomenon of burning oil.
However, in the face of all kinds of oil use theory on the Internet, the old drivers must also be confused, today Xiaobian will take stock of the misunderstanding of oil use, see if you have been recruited?
Myth 1: Mixed oil
The problem of mixed use of motor oil involves the mixing of new and old oils of the same brand, the mixing of different brands of oil, the mixing of different label oils, etc., which is one of the common misunderstandings in the use of oil. First of all, the problem of mixing new and old oils, old oils have been polluted and oxidized after a long time of use, and the performance is not comparable to new oils, and mixing is easy to aggravate the wear of auto parts. Different brands of oil manufacturing standards and functional emphasis are different, and mixing will also affect the performance of the oil. Different labels of oil can not be mixed, they focus on different models, forced mixing will damage the engine.
Myth two: engine oil is expensive
As the saying goes, "a penny for a penny", expensive oil must have an expensive reason, choose expensive oil is not wrong, but in fact, this theory has a premise. At present, the oil circulating in the market is various, the price is also uneven, and it is unscientific to use the price alone to select the oil. The choice of oil should be bought according to the needs of the car model itself, the reference standard includes the specified oil series, the use level, the viscosity of the oil, etc., the standard is different from the price, and the most suitable oil for your car may be a little cheaper.
Myth three: the viscosity should be large
The four words "too much" are the solution to this misunderstanding of oil use. The oil itself has a lubricating effect, and good fluidity can make the auto parts get excellent lubrication, so that the interaction between the components is more coordinated. If the product is selected according to the standard of the larger the viscosity of the oil, the better, it will increase the lubrication obstacle and accelerate the wear between the parts.
Myth 4: Add more oil
Adding less oil will make the lubrication effect worse, but adding more oil can make the auto parts get sufficient lubrication? In fact, too much oil will lead to waste, they will enter the combustion chamber to form carbon deposits, not only will cause failure, but also will in turn contaminate the oil itself. Therefore, the amount of oil added is only an appropriate amount, and it is best not to exceed the scale of the oil gauge.
