Which is better, 5W30 or 0W20, and which is more resistant to high temperatures?

There are 6 types of oil in winter, 16 types in summer, and general purpose motor oils in winter and summer. With such a complexity, how can our car owners distinguish it? In fact, it is very simple, the smaller the number in front of w, the better its low-temperature fluidity.

The higher the number after w, the greater the kinematic viscosity at high temperatures.

In addition, the most mainstream winter and summer general engine oil has been developed, such as our common 5W30, 5W40, etc., the smaller the number in front of W, the larger the number behind the big deal, which means that the oil has a wider range of adaptability.

0w20 and 5w30 are two completely different types of engine oil, 0w20 is mainly used in Japan, the United States, South Korea and other automobile engine clearance is larger. 5W30 is mainly used for German and other automobile engines with more fine engines. In short, following the manufacturer's guidance is the most scientific. Hope!

In addition, according to the specific driving location of the vehicle and the viscosity and actual quality of the oil, the maintenance personnel will choose the appropriate oil for local use according to experience, and there may be fine-tuning.

The W in the middle of 5W30 is the initial letter of Winter, the number in front of W represents the viscosity of the oil at low temperature, the smaller the number before W, the smaller its low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature (winter temperature); The number after w represents the viscosity of the oil at high temperatures, and the higher the number in the summer part, the higher the viscosity and the larger the applicable temperature range.

The difference between 0w20 and 5w30 motor oil is that the former is less viscous than the latter, both at low and high temperatures. Judging from the number alone, the former is a pure winter engine oil, and the latter is a winter engine oil commonly used in the north. The former is an uncommon type of motor oil, while the latter is more common.

The oil with low viscosity in winter is not easy to solidify even at low temperatures, making it easy for the vehicle to start, and after starting, the lubricating oil is required to have a slightly higher viscosity to reduce wear. Adding a slightly more viscous oil to the vehicle may take a little bit of oil. Of course, the primary purpose of adding engine oil is to lubricate and protect the parts, prolong the life of the car, and save fuel as a secondary consideration.

In addition, after the vehicle is started, the temperature of the engine is similar in winter and summer, and the size of the number after W does not affect too much, as long as it is selected according to the vehicle manual.

According to my driving experience after changing the oil, as long as it does not affect the start of the vehicle, the viscosity of the oil is still slightly larger, and it feels smoother when driving.

4S changed the type of engine oil, as long as the oil makes the car easy to start in winter, the new oil should have a stronger protective ability.

5W30 and 0W20 are not the same mark, the viscosity is higher and the high temperature resistance is relatively better, but it is still necessary to choose according to the viscosity recommended by the vehicle, I am the viscosity of 20, directly on the G T Magic Red Class IV PAO base oil.

PAO+ ester is no different from normal at high rpm in summer, the engine itself is also very good, and high-quality engine oil can better improve and increase the driving experience.

5W-30 engine oil is more versatile, more adaptable, and its characteristics are that the temperature can be adapted to all parts of the country, and there is no problem in the north, south, winter and summer. The 0W-20 mark is relatively thin, not all cars can be used, if the brand of engine oil movement viscosity is low, such as the use of German cars will exacerbate the phenomenon of burning engine oil. ”

Look at your car's maintenance manual, which has the applicable oil model, don't add it yourself.

Summary. Hello dear, 0w20 oil and 5w30 are better than 5w30. 5w30 is a more balanced oil.

It not only has the lubrication and cooling effect of SE, but also cooperates with the unique oil formula, which is of great help to both the fuel economy of the car and the low-temperature starting energy. Even when the engine is started at lower temperatures, the oil is easy to get you up to. <>

<> which is better, 0w20 oil or 5w30.

Hello dear, 0w20 oil and 5w30 are better than 5w30. 5w30 is a more balanced oil. It not only has the lubrication and cooling effect of SE, but also cooperates with the unique oil formula, which is of great help to both the fuel economy of the car and the low-temperature starting energy.

Even when the engine is started at lower temperatures, the oil is easy to get you up to. <>

The functions of <> engine oil are: 1. Lubrication, 2. Auxiliary cooling and cooling, 3. Cleaning and cleaning, 4. Sealing and leakage-proof, 5. Anti-rust and anti-corrosion, 6. Shock absorption, buffering, and anti-wear. Engine oil, also known as engine oil, is made up of base oils and additives.

Engine oil is divided into viscosity: 1. Four-stroke engine oil; 2. Two-stroke engine oil. <>

<> maintenance of car oil is to change according to the mileage, you can also check the quality of the oil, if you use general oil, then you must always check the quality of the oil, the oil lubrication is not good for the vehicle will be damaged. When the oil has been used for half a year, check it once a month or before leaving the car, take out some oil from the oil dipstick to see the oil level and the quality of the oil, continue to use it if you feel good, and replace it immediately if the quality is poor, so that the degree of damage to the car will be reduced. <>

0w20 oil is better.

0W20 engine oil has stronger low-temperature fluidity and cold resistance than 5W20 engine oil. w stands for winter, which means to be used in winter. The lower the previous value, the better the fluidity of the oil at low temperatures.

20 represents the viscosity of the oil at 100. The higher the value, the higher the viscosity and the higher the high temperature resistance.

The difference between 0w20 and 5w20 is the number in front of w. 0w20 can work at a low temperature of minus 35 degrees, 5w20 can only work below minus 30 degrees, the smaller the number in front of w, the better the low temperature fluidity of the oil, it can be used in the case of low ambient temperature, and the better the protection ability of the engine when the car is cold started.

W is the English abbreviation of winter, which means that it can be used in winter. The higher the number, the better the protection performance of the oil at high temperature.

Engine oil can be said to be the blood in the car, is the most important component, it can play a role in lubrication, cooling, anti-corrosion, anti-wear and other functions of the engine, is very important.

The range of use of the two types of oils:

W20 oil use range:

5W means that the oil can withstand a low temperature of minus 30, that is to say, this type of oil can still play its role at minus 30, if the number in front of W is 10W, it means that the oil can withstand a low temperature of minus 20.

W20 oil use range:

0w20 engine oil is adapted to the temperature of more than minus 35 degrees Celsius, and the viscosity is relatively low, suitable for new cars with small engine clearance, due to the small viscosity of 0w20, with excellent oil fluidity, it is of great help to the fuel economy of the car.

Hello dear <>

Personally, I think 5w30 engine oil is good. The main function of engine oil is to provide lubrication and reduce friction for the engine, and at the same time, it must also have the properties of cooling, anti-wear, anti-rust, cleaning, etc., which determines the service life and performance of the engine. Both 0w20 and 5w30 oils can provide good lubrication and protection, but they have some differences when used.

0w20 engine oil is a relatively new engine oil specification, it is a fully synthetic engine oil, more suitable for high-performance engines. This oil is widely used and has excellent performance in terms of wear prevention, fuel economy and cooling. In addition, the low viscosity of 0w20 oil allows the oil to flow faster through the engine and lubricate the engine.

5w30 engine oil is a more conventional engine oil specification that is commonly used in different models and engine types on the market. This oil has good wear resistance and applicability, can be used stably in different vehicle conditions, and can also indicate good lubricating performance at high speeds. In addition, the high viscosity of 5w30 engine oil can reduce the leakage of the hair beam leakage to a certain extent.

To sum up, the choice of engine oil also needs to be comprehensively considered according to the specific situation and environment of the vehicle. If the vehicle is a high-performance engine or needs to drive frequently in a high temperature environment, it is recommended to choose 0w20 engine oil. If the vehicle is a popular model in the market, you can choose 5w30 engine oil.

But no matter what kind of oil, it is recommended to choose a qualified oil brand and change the oil at the stipulated time.
