What about the quality of Castrol EXTREME 5W 40 A3 B4 4L? How much does it cost?

Hello, Castrol EDGE 5W-40 (A3 B4) 4 liters of good quality, ** about 300.

Hello, Castrol EDGE motor oil is fully synthetic, and the ** in the general market is around 120 per liter. You can buy it with confidence.

The quality is still very good,**About 400 yuan, in addition, it is best not to go to online shopping, if you have the conditions, it is best to buy in a physical store, after all, there are more fakes on the Internet, in addition, this oil is very good whether it is low temperature fluidity, or the viscosity of the oil.

Hello. This oil is fully synthetic, stable and ready to use.

**About 300.

Castrol EXTREME, this fully synthetic motor oil. Buy it online for about three or four hundred yuan. The oil is still very good.

Hello, Castrol's car engine oil is still very good, but the extreme protection engine oil is generally a little more expensive, and it is normally about 100 yuan a liter.

Hello, I personally recommend that it is best to go to the local four-S shop for maintenance, and follow your maintenance manual for maintenance and maintenance.

It should be said that as long as you buy the best brand, then it should be said that its quality is absolutely fine, that is, **, it depends on which dealer you go from.

Castrol EDGE 5W-40 (A3 B4) 4L quality advice is good, I have been using this oil.

Hello, Castrol, there is no problem with this brand of engine oil, and the user feedback is quite good, so buy with confidence.

Castrol is a motor oil brand, and A3B4 is the model number.

AXBX is the grade of engine oil, A5B5 is the highest level, A3B4 is worse, but most of the time it is still more to look at SN and SL levels, A1 B1A5B5 or A1 A5 represent viscosity oil and A3 B4 represents viscosity oil is relatively large, that is to say, 5W30 is relatively larger. 5W 30ACEaA3 B4 Viscosity Index 12 0 12 5,5W 30ACEaA1(A5) B1(B5) Viscosity Index 10 5 11.

OK. 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 conditions, separating metals and reducing 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.

Extreme protection 5W-40, 100 degree kinematic viscosity; The 40 degree kinematic viscosity can be ignored, and the high-temperature shear value must be above.

Castrol EXTREME Synthetic Motor Oil is based on Castrol's 100 years of experience in manufacturing lubricants and is designed for those who love cars. Extreme Protection is a high-end car oil that delivers superior engine performance even in demanding environments.

1. If a barrel of engine oil cannot be used up at one time, you can put plastic on the bottle mask, screw the cap on, seal it and store it for the next time.

2. Pay attention to protecting the environment and properly dispose of waste oil.

3. Avoid long-term or repeated contact with ** Do not store in a place with strong sunlight, humidity, severe cold or more than 60 degrees Celsius.

4. Oil replacement cycle: the mileage of the first oil change of the new car is shorter, and it is stipulated in the car instruction manual, in the future, every 5000 kilometers - 10000 kilometers to change the oil, if the car is used less frequently, it will take several years to run 10000 kilometers, then change it according to the time, you can change it once a year, but the replacement cycle can not be too long, because the oil will deteriorate after a long time.

How to choose. When choosing a motor oil, you should mainly look at its viscosity index (refer to the classification of viscosity index in the knowledge hall), speed (depending on your general driving conditions), engine load level (see the table below) and temperature (depending on your driving environment) are the three main factors in choosing viscosity, the higher the speed, you should choose the oil with low viscosity.

The higher the load, the higher the viscosity oil should be chosen, and the higher the temperature, the higher the viscosity oil should be chosen.

Castrol EDGE 5W-40, 100 degree kinematic viscosity; 5W-30, 100 degree kinematic viscosity.

W for winter, 5w for 40 for oil, suitable for use at minus 30 minus 40 degrees Celsius. The smaller the number before w, the better the performance.

1. Different properties: the numbers 40 and 30 after 5W represent the viscosity, the larger the number, the greater the viscosity, and the higher the applicable maximum temperature. In other words, 5w40 can withstand higher temperatures than 5w30, and high-viscosity oils (with higher values) may also be more suitable for high-speed or heavy-duty vehicles.

2. The characteristics are different: 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. Using an oil with a lower value in front of the engine makes it easier to start the engine in cold weather.

So which one is better, it mainly depends on the environment in which the vehicle is driving, if it is a hot area like Hainan in China, it is better to use 5w40, if not, it will be better to use 5w30.

3. The principle is different: FE is a fuel-saving sign, and the car engine is represented by A, with A1, A2, A3, and A5, and the more stringent it is.

Castrol EDGE is a motor oil for motor vehicle engines, and the numbers and letters that follow it indicate different viscosity grades and specifications. The following is an explanation of the difference between Castrol EDGE 0w w-40:

1.Viscosity Grade:

0W-40: This oil has a very low viscosity at low temperatures, making it suitable for starting engines in cold environments. The number 0w represents its fluidity at low temperatures.

5W-30: This oil has a lower viscosity at low temperatures, making it suitable for lower temperature start-up requirements. The number 5W represents its fluidity at low temperatures.

5W-40: It means that this oil has a certain viscosity at low temperatures, which is suitable for general low temperature starting requirements. The number 5W represents its fluidity at low temperatures.

2.Temperature Adaptability:

0W-40: Suitable for cold climatic conditions due to its very low viscosity, it is able to quickly lubricate the engine at very low temperatures, reducing wear and friction at start-up.

5W-30: Suitable for engine protection in general climatic conditions, providing low cold-start friction and good thermal stability.

5W-40: Suitable for engine protection in general climatic conditions, providing some cold start protection and thermal stability.

It is important to note that the choice of oil should be based on the recommendations and requirements of the vehicle manufacturer to ensure that the oil selected meets the specifications and performance requirements of the engine. Different engine designs and operating conditions may require oils of different viscosity grades and specifications. Therefore, it is best to refer to the advice provided by the car manufacturer when choosing a motor oil and follow the relevant regulations.

The viscosity is different. 0W or 5W indicates oil characteristics that support cold-start performance. Oils with lower pre-W values are easier to start in cold weather.

40 indicates the viscosity of the oil when the oil is at operating temperature. If the vehicle is operating at high speeds or under extreme load conditions, it is more suitable to use an oil with a higher viscosity.

A 0w40 oil is easier to start in cold weather than a 5w40 oil.

The meaning of SAE designator, SAE is the abbreviation of the American Society of Motor Vehicle Engineers. The label behind SAE indicates the viscosity value of Saezhao early Ming engine oil, such as: SAE5W-40, where "W" represents winter, and the number in front of "W" represents the flow viscosity under low temperature.

The higher the number, the higher the viscosity, the better the protection of the guess section engine at high temperatures.
