What type of engine oil is suitable for high speed?

First of all, it must be a fully synthetic engine oil, and the label should be in accordance with the original manufacturer's recommended value. The protection of the high rotation of the engine with fully synthetic engine oil is more in place, and the oil change interval is more than 8000 kilometers, and the big brands are about 1w kilometers. Fewer maintenance times not only save time and costs, but also machine filtration and labor costs.

In addition, if you often run at high speeds, the attenuation of the engine oil will be relatively small, and the oil change interval can be appropriately extended, which is more worry-free.

In terms of low attenuation and long-lasting performance in fully synthetic motor oils, Mobil is the first to be recommended. According to the different use environment, the oil change cycle of Silver Mobil is generally 1, and the oil change cycle of Gold Mobil is generally the oil change cycle of the American version of Gold Mobil in the United States, and it can also reach about 2W in the domestic driving environment).

There is also a GT magic red that has been used by netizens before, this oil has some "false standards" in performance, and the actual performance is better than the nominal one.

Take Jin Mobil 0W40 and GT Magic Red 0W40 as an example, the official performance indicators of these two engine oils are almost identical, but GT's PAO base oil content is higher, the low-temperature fluidity is better than that of Jin Mobil, and the 40° sports viscosity is also slightly lower, so it feels that the throttle is lighter and faster, and the acceleration is faster, so many riders praise GT Magic Red as a god oil. But it's embarrassing to compare the price, the Bank of China Jin Mobil 0W40 sells 385 for a certain East 4L, GT Magic Red regular channels are cheapest to 512, the oil change cycle is right, and the engine noise with GT Magic Red will be louder, so for users who do not pursue the ultimate power, GT Magic Red is not cost-effective.

For the driving environment of the landlord, it is enough to change the silver Mobil every four months, or the gold Mobil every five or six months. Although GT Magic Red has good performance, it can only drive to Silver Mobil mileage for a quarter more expensive than Gold Mobil, so it is not recommended.

1. The displacement of the car is so large, and it will not bring a strong sense of pushing back.

2. The original engine oil is fine, so you don't need to worry too much.

The quality of the GT Magic Red engine oil used today is very high, because it uses four types of PAO engine oil, and the highest quality engine oil is also very good to drive, so it is more comfortable to use. The oil contains liquid molybdenum in it, and the anti-wear is particularly good.

The quality of different brands of engine oil is not the same, there is no best, but the main comprehensive performance of the Mobil or Magic Red oil power is not bad, I have used, with the love of stepping on the oil, from Mobil to now G T Magic Red oil, four types of PAO base oil power experience full marks, stepping on the oil sound is low and powerful, the throttle has been very light, the driving experience is the best I have used the oil.

As we all know, engine oil is like blood to provide effective protection for the engine anytime, anywhere. Each vehicle has its own established standards for oil usage in the design and production process. During use, with the increase of internal wear and tear of the engine and the influence of external factors such as carbon deposits, it is more important for the owner to choose the right engine oil.

Traditionally, engines with older engine life or severe internal wear and tear are more suitable for slightly higher viscosity oils, but at the same time, many car owners who prefer to drive hard cars believe that they should also use higher viscosity oils.

So is that really the case? Driving hard, it is easy to keep the engine in a state of high temperature and high rotation, which will indeed bring some problems to the oil, because the long-term high temperature and high rotation will accelerate the increase of the acid value of the engine oil, and then produce high-temperature sludge, which will lead to problems such as the decline of the oil's oxidation resistance, thereby shortening the service life of the oil.

Friends who often drive violently, when choosing oil, you can first consider synthetic engine oil with higher overall antioxidant capacity, or you can consider engine oil with higher oil film strength at high temperatures. Therefore, the oil with higher viscosity is less prone to film cracking under high temperature and high load, and can indeed play a certain protective role.

At the same time, the higher the viscosity of the oil, the better its shear resistance theoretically, and the shear resistance is an important indicator to measure the quality of the oil.

How to understand shear resistance? Let's take out a napkin. The better the shear resistance of the napkin, the less likely it is to break when we wipe our hands or mouth, and the same goes for oil.

The better the shear resistance of the oil, the less likely it is that the oil film will break under external tearing and the more durable it will be to protect the inside of the engine. The difference between high viscosity and low viscosity is like the difference between several napkins stacked on top of each other to wipe your mouth and just one napkin. The more the napkin is folded, the less likely it is that the napkin will break naturally when you wipe your mouth.

However, it is important to note that oils of the same viscosity do not have the same shear resistance, so the difference between them must be small. For example, if two brands of paper towels have the same thickness, perhaps one of them has a better "soulmate" potato roll than the other, because the additives are different between different brands of engine oils.

The oils we use in our daily lives are basically multi-grade oils, which generally require viscosity index improvers, and the quality and quantity of these additives determine the shear resistance of the oil.

If synthetic base oils are used, less of these polymers can be added due to their good viscosity and temperature properties, so the shear stability will be better. That's why one of the selling points of Shell's extraordinary synthetic oils is their good shear stability and the ability to adapt to higher engine speeds. This is also the reason why Bian Xiao suggested that friends who drive violently try to use synthetic motor oil.

In summary, while it is theoretically possible that a higher viscosity of motor oil will make the oil molecules larger, does this mean that the chain of oil molecules it forms has a higher resistance to shear? It's still not the same. After all, the costs and profits involved behind each brand are different, and the performance of the products produced by them will also be different.

Millions of car purchase subsidies.

It can be said that the quality of the three major engine oil brands of Mobil, Castrol and Shell is very good. Each one has its own characteristics, car owners can choose according to their own needs, and for different people, the needs are different, the oil used will be different, so it is difficult to say which oil is the best and most practical, suitable for others, is the best and most practical, but not necessarily for themselves.

Most of the recommended oil viscosity index for Japanese and Korean cars is 0w20 or 5w20On the whole, the viscosity is lower than that of the 5w30 engine oil recommended by the United States and Germany, that is, it is thinner. This not only means that Japanese cars have high assembly accuracy, but also that the fluidity of the engine oil has less resistance to the moving parts of the engine, which can improve fuel economy.

However, when the vehicle is used for a certain period of time, the gap between the engine parts will become larger due to wear, that is to say, the close relationship between the parts is no longer close, so that if the oil with low viscosity continues to be used, the lubricating oil film formed by the oil between the parts will be too high fluidity, resulting in the oil film is not stable, thereby reducing or losing the lubrication ability.

Fully synthetic engine oil, choose the right engine oil according to the region.

The engine oil with better comprehensive performance is like Mobil or G T Magic Red engine oil is very good, I run at high speed and more, I have been using G T Magic Red engine oil, the base oil of the four types of PAO runs at high speed and the power is accelerated rapidly.

It is better to choose a fully synthetic engine oil, and how to change it has a longer cycle.

Toyota cars are recommended to use pure brand engine oil, which is the after-sales service oil of Toyota cars, which belongs to the original engine oil.

Whenever possible, use a less viscous oil to keep the oil path open. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear.

1.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

2.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

3.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

Try to choose multi-grade oil, multi-grade oil has a better protection effect on the engine due to saving, long life and high efficiency. Due to the characteristics of multi-grade oil, there may be premature blackening and less oil pressure than ordinary oil during use.

Hello I often have to use high-grade PAO engine oil on the high speed, I also often run at high speed, I bought the German GT engine oil, is PAO engine oil, and the power is also up with 10,000 kilometers.
