Can you use 5W40 fully synthetic Castrol engine oil?

Yes.

Castrol Magnetic 5w40 is a fully synthetic engine oil, in the past, the magnetic protection 5w40 was a semi-synthetic oil, and the barrel was written as synthetic engine oil, but now it has been upgraded and become a fully synthetic oil, and it is written on the magnetic 5w40 barrel that is fully synthetic. Now Jingdong Tmall and other ** sell fully synthetic oil, and it is difficult to find semi-synthetic oil magnetic protection 5w40.

Castrol Magnetics is now all fully synthetic, and in this range, in addition to magnetic oils, there are also magnetic start-stop oils and magnetic SUVs, but both have always been fully synthetic lubricants. In contrast, in terms of thermal stability, oxidation resistance and viscosity resistance, fully synthetic oils are superior to semi-synthetic oils.

Precautions for the use of fully synthetic motor oil.

Fully synthetic engine oil is recommended for turbocharged vehicles: Turbocharged engines are very popular engines today, and we need to use fully synthetic engine oil. An engine with a supercharger gives a refreshing push back feeling when accelerating, but the engine torque increases exponentially the moment the turbine starts working.

According to the principle of turbocharging technology, the oil film covering the engine crankshaft at this time is subjected to several times higher shear force than before, so it is necessary to use fully synthetic engine oil to meet the various working conditions of the turbocharged engine.

What is written on the shell is synthetic, in fact, it is semi-synthetic engine oil, and fully synthetic motor oil will be written directly and clearly, so as not to be misled. Castrol's main protection function, driving by yourself is a bit capricious, more pursuing the feeling of power, and then now it will be replaced by GT magic red imported from Germany, PAO base oil, and there is a feeling when you step on the accelerator.

German engines, or vehicles with a long service life and greater wear, such as driving more than 100,000 kilometers, can be used, 5w40 belongs to the higher viscosity of the oil, if it is the United States, Japan and South Korea, it is not recommended to use this viscosity oil, cold start will wear out, and the power will drop, fuel consumption, hope.

5w30。Castrol 5W30 and 5W40 have the same minimum temperature, which means that the low-temperature fluidity and low-temperature start-up performance are the same. The difference is the high temperature performance of the two, the maximum temperature that 5w40 can apply is higher than that of 5w30, that is to say, in the environment of 100, the viscosity of 5w40 oil is greater than that of 5w30, and the stronger its high temperature stability, the more it can protect the engine under high temperature conditions.

Precautions for the use of fully synthetic motor oil.

Those large-displacement SUVs or sedans are also best suited to use fully synthetic motor oils. The reason is that the weight of a large-displacement car is much greater than that of an ordinary car, and the output of the engine is very high, which will cause the working temperature of the engine and oil to be much higher than that of an ordinary car.

These large-displacement engines are often equipped with an additional "oil radiator" to ensure the oil temperature and avoid wear caused by the loss of oil film strength. Therefore, large-displacement vehicles have higher requirements for the performance of engine oil, and it is recommended to use fully synthetic engine oil.

Castrol 5w30 and 5w40 depend on the quality of the oil, if it is a fully synthetic oil, 10,000 kilometers is no problem. If it is not fully synthetic, it may not reach 10,000 kilometers. The engine oil I use is G T Magic Red, which is a four-class PAO, long-lasting and durable, and can be driven for 15,000 kilometers at a time of maintenance, which is more durable than the general three-class fully synthetic engine oil.

First of all, 5w30 and 5w40 are a series of engine oils, but the viscosity is different, and the difference will not be very large. I usually run at high speeds, and I directly upgraded to G T Magic Red, and it took 10,000 kilometers for the four types of PAO + esters to attenuate, which is easy to use and worry-free.

Castrol EDGE 5W30 is a fully synthetic oil with titanium fluid reinforcement technology, which changes the physical structure of the oil and hardens under extreme pressure conditionsSeparates metals and reduces friction between metals. When the pressure drops, the oil returns to a free-flowing state. Stronger performance can be inspired under pressure, reducing friction by 20% that can lead to performance degradation.

5w30 This viscosity grade is suitable for all-weather use and can be used all year round. It has good low-temperature performance, good low-temperature fluidity, and can better guarantee cold start, while low high-temperature viscosity, more fuel-saving, and more powerful power output.

Jihu 5W30 is suitable for use in mid-to-high-end vehicles with low temperature in winter driving environment and high power requirements, and the minimum temperature can be applied is minus 30 degrees Celsius.

Car owners should keep in mind when choosing engine oil.

To choose a lubricant that meets the viscosity grade of your vehicle, you should consider the maintenance requirements of your vehicle, the long-term driving environment of the vehicle, and the road conditions. The right oil can better protect the engine and play a better role in the oil.

If the viscosity does not match the oil, it will cause different degrees of damage to the engine, such as excessive viscosity and more power loss; If the viscosity is too small, it is difficult to form a good protective film, which cannot play a certain lubricating role, resulting in friction between parts and damaging parts.

Yes. Engine oil classification: The engine oil label includes two parts: classification and viscosity specifications.

Identification: The viscosity of lubricating oil is mostly marked by SAE and other grades, and SAE is the abbreviation of the English "Society of Automotive Engineers". w stands for winter (winter), the more ** the number in front of it, the better the low temperature fluidity of the engine oil, the lower the ambient temperature available for use, and the better the protection ability of the engine during cold start; The number after the "W" (after a horizontal line) is an indicator of the high temperature resistance of the engine oil, and the higher the value, the better the protection performance of the engine oil at high temperatures.

The engine oil on the market may also be G T magic red engine oil PAO base oil content is relatively high, the content is more than 50%, many engine oils are only about 10%, the difference is still relatively large, no wonder many high-end cars are used, the quality will be more reliable. The most important thing is in terms of power, before using extreme protection, I feel that the power can't go up, and the stamina will be a little insufficient, GT engine oil will not have this problem at all, maybe I bought a fake by myself, Castrol engine oil has many sales channels, and it is easy to buy fakes.

Extreme protection is containing PAO base oil, fully synthetic engine oil is basically contained, is the content of the problem, I bought this G T magic red engine oil, but also value PAO base oil, it turns out that I bought it right, it is indeed better than the engine oil I used before, long-term anti-attenuation, can be used for a longer time, and the driving experience is also good.

The magnetic protection series engine oil is a semi-synthetic oil, with weak anti-attenuation ability, fully synthetic engine oil is stronger than it, and the anti-attenuation ability of PAO base oil is stronger. Like Kim Mobil and G T Magic Red, I am now using G T Magic Red, which not only has a long replacement cycle, but also the oil port is cleaner than before, and you can see the metallic luster.

Castrol EDGE is not fully synthetic, it is a semi-synthetic motor oil. I've been using Castrol because of its advertised cold start, but in reality it's still a long wait to warm up in winter. Later, I was troublesome and simply upgraded to four types of PAO engine oil GT engine oil, and the hot car time was significantly shortened, and the silence was surprisingly good.

Castrol EDGE 5w30 is slower to attenuate, longer than other oils, but basically 5000 kilometers to start attenuation, like I drive more often, not very suitable. G T magic red oil attenuation period can be as long as 10,000 kilometers, is now the slowest attenuation of the engine oil, the oil change cycle is also relatively long, up to tens of thousands of kilometers, the oil service life is long, not easy to attenuate performance will be much better.

Castrol EDGE is a fully synthetic motor oil, I have used it twice before and the performance is still good. I am now using G T Magic Red engine oil, this engine oil is of high quality, it is a four-class PAO, it can be changed once every 15,000 kilometers, the performance is very good, and the cost performance is super high. I've been using it all the time, and the quality is really good.

It feels good to use, too.

5W of 5W-40 oil represents resistance to external low temperatures of -30°C.

0w in the 0w-40 engine oil represents the external low temperature resistance is -35.

The grades of winter oil are: 0w, 5w, 10w, 15w, 20w, 25w, and the symbol w represents the abbreviation of winter (winter).

The smaller the number before w, the smaller the low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature, which means that the lower the ambient temperature available for use, and the better the ability to protect the engine during cold start.

Q: Does changing the oil have an impact on the engine?

Engine oil, that is, engine lubricant, English name: engine oil. The density is about to lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine.

A good engine oil can reduce the wear and tear of engine parts, extend the service life and improve the feeling of using the car.

Different engines generally have specified requirements for oil types.

It is also best to choose the right oil for your vehicle.

Question: Volkswagen Magotan can be fully synthesized with 5-40.

Hello, you can.

Magotan generally uses 5w30 type of oil, compared with 5w40, the viscosity of this type of oil is smaller, the fluidity of the oil is also better, according to the structure of Magotan engine and its working conditions analysis, 5w30 type oil can meet the needs of the engine. However, if the driving conditions are more severe, you can appropriately increase the viscosity of the engine oil and use 5w40 engine oil to better protect the engine.

Magotan generally uses 5w30 type of oil, compared with 5w40, the viscosity of this type of oil is smaller, the fluidity of the oil is also better, according to the structure of Magotan engine and its working conditions analysis, 5w30 type oil can meet the needs of the engine. However, if the driving conditions are more severe, you can appropriately increase the viscosity of the engine oil and use 5w40 engine oil to better protect the engine.

From the above, you can see that there is only the difference between 0w and 5w, w stands for winter, which means winter, oil is used in winter, the smaller the number in front, the better the low temperature fluidity, 0w represents the low temperature fluidity of minus 35 degrees, and 5w represents the low temperature fluidity of minus 30 degrees, so it is more suitable to use 0w engine oil in the north!

The latter 40 represents high temperature fluidity, so the weather in the south is very hot, suitable for the number of 30 or 40, so 0w-40 or 5w-40 is suitable for winter and summer engine oil!

This is a label for the viscosity of motor oil issued by SAE (Society of Automotive Engineers), SAE specifies 11 oil viscosity grades, indicating what grade of engine oil to use at what atmospheric temperature. 6 of these 11 grades are winter engine oils, which are represented by the English letter W, respectively 0w, 5w, 10w, 20w, and the number in front indicates the minimum temperature applicable to the grade of engine oil, the smaller the number, the lower the temperature.

Stable performance, safe and reliable, durable, not afraid of corrosion, not afraid of water. Synthetic engine oil, using instantaneous core molecular technology, can be activated under high temperature and high pressure conditions, inhibit oil oxidation, and form a protective barrier, providing long-lasting and comprehensive protection for the engine, upgrading to fully synthetic base oil, stable oil quality, higher performance.

A good engine oil for all kinds of family cars.

Castrol 5W40 fully synthetic engine oil is a fully synthetic lubricant that uses titanium fluid reinforcement technology to provide twice the strength of the oil film, which can effectively prevent parts damage caused by the rupture of the residual oil film. Due to its high viscosity value, JIH 5W40 is more suitable for high-speed or heavy-duty vehicles.

Jiafeng Lushi Multi Magnetic Protection 5w40 fully synthetic engine oil index is suitable for German cars and older cars with a minimum temperature of minus 25 or more.

Because the oil of 40 can still maintain a relatively high value at a high temperature of 100, the viscosity is high, the shear pressure coefficient is high, which meets the high standard requirements of German cars, and the sealing of old cars is not as good as that of new cars, which requires high viscosity value of oil to improve its only first sealing, so the magnetic protection 5w40 is more suitable for the above models.

Castrol Magnetic 5W40 This oil is a fully synthetic lubricating oil, usually can run 10,000 kilometers, or change the oil after one year, but in the actual situation, it is necessary to combine the driving environment and road conditions of the vehicle for a comprehensive judgment, it is recommended that the owner should change the oil in advance, and you can go to the maintenance shop for testing, change the oil, and do a good job in engine maintenance at about 8000 kilometers.

Magnetic protection 5w40 true and false identification method:

1. Smell the smell: **The engine oil is slightly aromatic and has no peculiar smell. Fake oil is filled with a smell of gasoline and diesel, and it has a very pungent odor.

2. Look at the oil quality: ** The engine oil is light yellow and transparent, without impurities and sediments, and the fake oil is generally processed from recycled engine oil or waste engine oil, with a transparent black and bright color and high viscosity.

3. Look at the packaging: **The packaging bottle body is exquisitely worked, and the details are flawless; Counterfeit products have rough workmanship and color differences.
