First of all, excluding the Mobil series, I myself don't have great requirements for sound, but after changing the Kim Mobil once, I really feel that the sound is a bit noisy. Secondly, Shell and Castrol are okay, but the power may be difficult to meet the diesel engine. I recommend the PAO class to the point, because I have the best experience of changing the imported GT engine oil, and the sound is also the most comfortable, and the feeling of being at ease is the most comfortable.

Shell, as one of many motor oil brands, is both fuel-efficient and quiet.
Among them, the gray shell engine oil is mainly used for silence, with Shell's advanced power cleaning and dispersion technology, which is specially designed to prevent dirt particles from agglomerating and forming sludge, in terms of removing oil sludge is four times that of ordinary mineral oil, in addition, an important function of the gray shell is to lubricate the engine parts of the car, so that they run more smoothly and obtain better engine performance.
Precautions and key points for engine oil:
Motor oil does have its expiration date, which can be seen on the product box. In the case of sealing, the general shelf life of motor oil is 5 years; However, if you have used it before, and then tighten the lid and continue to sit idle, its shelf life will only be about 2 years; If you use it after it has expired, the deposits at the bottom of the oil will increase significantly, and you need to filter out the deposits inside before using them.
Moreover, its effectiveness will be greatly reduced. Although it does not damage the vehicle, it is still recommended to use it within the warranty period. Generally speaking, if the engine oil expires, it cannot be used in principle.
Because engine oil is a highly absorbent substance, it will absorb moisture in the air for a long time, causing oil deterioration.

If you want to make less noise, as long as you don't use the original factory, because my car has been used before, the disadvantage is that the noise is loud, and it is uncomfortable to run more people, and it has to be the magic red engine oil I use now, with the addition of liquid molybdenum, the anti-wear protection ability is very good, the mute effect is obvious, and the fuel consumption is half lower than before, and the maintenance experience is much better.
-
I can change the GT Magic Red engine oil to use, I am now changing this engine oil with particularly high quality, using PAO base oil and liquid molybdenum additives, the composition is particularly good, and the driving feeling of the car has always been in a state. The driving power is particularly sufficient, and the car drives fast, the engine sound is still very strong, and the feeling of driving is much improved. I usually walk some difficult roads, and the power of the car is completely OK, so it is not difficult to run at all.

Currently, Shell.
The quieter effect of the engine oil will be better, this brand is also one of the world's three major lubricant brands, and the performance is also good in other aspects, and it also focuses on cleaning performance. Fast and silent engine oil can be recommended to use Shell gray shell engine oil and German GT engine oil.
But in addition to choosing the brand, the choice of viscosity grade will also affect the mute effect. If the oil is used with too little viscosity, the oil film formed by the oil on the friction surface of each part is thin, and the parts that move with each other cannot be separated, and when running, the parts will collide with each other and friction, which is also one of the reasons for the noise. Therefore, after deciding on the brand of engine oil, we need to learn how to choose the right viscosity grade.
The selection of viscosity grade should be comprehensively considered in combination with the driving habits of the owner, the driving environment of the vehicle, the vehicle model, etc., and the maintenance manual of the vehicle should also be referred to. If the driving conditions are harsh and the temperature is low, you need to use a 0W or 5W series oil.
If it is a new car, the general high temperature viscosity value is low, you can use a 30 viscosity value of the oil, or even a 20 viscosity value can be; However, for old cars or old engines, oil with a viscosity of 40 is generally used, because the gap between the internal parts of the engine is large, and the oil with high viscosity value is required, which can form a thick oil film on the surface of the parts to prevent friction and wear between parts.
The viscosity grade will also affect the display of engine performance, so car owners should carefully choose the right viscosity grade for their vehicle.

It is a commonly used car engine lubricant for our car owners. It is called the "blood" of the car. Therefore, we must not be careless when choosing a motor oil brand. So, with so many products on the market, which brand of oil is the best? Is brand oil quiet?
Three brands of motor oils:
In fact, there is no best engine oil, only the best oil for us. If there really is the best engine oil brand, there will not be so many engine oil brands on the market. Most oil brands have their own unique features, so we need to choose for ourselves.
There may be many car owners who think that Shell oil should be the best one, but in fact, one of the most recognized points of Shell oil is its cleaning effect. Taking the Heineken series as an example, the biggest core technology content of its products lies in the unique active cleaning technology, which can effectively prevent dirt from disturbing the inside of the engine while cleaning the engine, so as to ensure the quiet and smooth operation of the engine, so it is recognized by the majority of riders.
However, Shell oil products cannot be used for long periods of time, and engine performance is unstable at medium and high speeds, which is the advantage of another brand, Mobil Oil. In the eyes of car owners who pursue oil quality, Mobil Oil is impeccable. In addition to the suitable performance of the oil itself, the performance index of Mobil oil is also quite high.
Most of the engine oil needs to be changed every kilometer, but high-quality Mobil engine oil can be used for 10,000 kilometers, which is also a major feature of synthetic engine oil - long replacement cycle, so too lazy to change oil, car owners who have no requirements for engine oil should choose Mobil oil.
In the cold old branch key area, due to the influence of temperature, the viscosity of the engine oil will become very high, which will increase the wear and tear of the engine during cold start, thus bothering riders in northern China, and Castrol oil solves this problem well. The biggest feature of Castrol is that it has good fluidity at low temperatures and has good cold start protection for the engine. Its unique magnetic protection feature means that even if the vehicle is parked for a long time, it will not completely flow back to the bottom, which will minimize the wear and tear of the engine the next time the vehicle is started.
Moreover, Castrol's cleaning ability and duration are not bad, so it also has a place in the market.
Silent effect: Asking whether the mute effect is good or not is actually asking whether the friction of the engine parts is small. When it comes to the above three common oil brands, Shell is the clear winner.
There are many types of Shell oil, one of which is Gray Shell oil, which is mainly used for mute. After using ash shell oil, it can not only effectively clean the dirt inside the engine and keep the engine running smoothly, but also has a significant lubrication effect, which can greatly reduce the engine noise. I believe that many friends who use it for the first time will be shocked.
However, the oil price with good silent effect is not low, and the stamina is insufficient. The oil change interval is much faster, and it is not stable enough when the engine speed becomes high. Therefore, if there are no special requirements, try to use other types.

At this stage, the actual effect of Shell oil oil is better, this brand is also one of the world's three major engine oil brands, and its performance in other fields is also very good, and it also focuses on cleaning performance. Fast acceleration and silent engine oil can be recommended to use Shell oil ash shell oil, French GT engine oil.
However, in addition to the selection of well-known brands, the selection of viscosity grades will also jeopardize the actual effect of mute. If the viscosity of the oil is too small, the oil slick oil generated on the friction surface of each part is thin, and the parts that operate with each other cannot be separated. Therefore, after identifying the well-known brand of engine oil, we must learn how to choose the right viscosity grade.
The selection of viscosity grade should be integrated into the overall consideration of the buyer's safe driving habits, the driver's natural environment, the car series and other fields, and it is also necessary to refer to the maintenance manual of the car. If the safe driving standard is extreme and low, you need to choose a 0W or 5W series of oils.
If it is a new car, the general high viscosity value is slightly lower, and the oil with a viscosity value of 30 can be applied, or even a viscosity value of 20; But for the car or the old diesel engine that is a little older than the old, the viscosity of 40 engine oil is generally used, because the void of each part of the automobile engine is relatively positive or large, the oil with high viscosity value must produce a thick slick oil on the surface of the part, so as to isolate the friction damage in the middle of the part.
The viscosity level can also affect the performance of the car's engine, so drivers need to carefully choose the right viscosity grade for the car.
