Maintenance and oil change is 5W 20, or 5W 30

Pay attention to the three major elements of oil change, and there are some detailed precautions, which are detailed as follows:

1. When should I change the oil?

If you care a lot about the vehicle in front of you and don't plan to replace it within ten years, it is recommended to replace it with 5,000 kilometers of ordinary oil and about 5,000-7,000 kilometers of synthetic engine oil. Don't think it's a waste to change early, and then compare similar cars after 5 years, whether in terms of power, fuel consumption or maintenance costs, you can see a huge difference. If you are good for the car, the car will be good for you!

Second, how to choose engine oil.

In general, the following four elements should be paid attention to when choosing engine oil:

1. The selection of engine oil should be selected according to the requirements of the engine, and it is not necessary to use too high-grade engine oil on the engine with lower requirements, nor can the lower-grade engine oil be used on the engine with higher requirements.

2. Multi-grade oil should be selected as much as possible, and multi-grade oil has a good protective effect on the engine due to its saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

3. The quality of some domestic engine oil is also good, and it can be used with confidence, and there is no need to blindly pursue "foreign oil".

4. If the engine is in good condition and the temperature is low in season, the oil with low viscosity should be used as much as possible to make the oil circuit smooth. 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.

3. When winter comes, the viscosity of the oil used in summer increases, the fluidity becomes poor, the friction resistance increases, the crankshaft rotation resistance increases, the piston and cylinder liner wear increases, and the diesel engine is difficult to start, which affects the power and fuel economy of construction machinery. Therefore, it is necessary to change the winter engine oil with good fluidity.

When changing the oil, try to use high-quality oil. This type of engine oil is not easy to oxidize at high temperatures, and will not form deposits in the delicate parts of the diesel engine, which can greatly extend the life of the diesel engine. On the contrary, if low-quality engine oil is used, it is easy to leave carbon deposits and sludge in the diesel engine, clog the filter and oil passage, and shorten the life of the diesel engine.

Single-grade engine oil has a narrow temperature range, and multi-grade engine oil can work in a wide temperature range, so it is advisable to use multi-grade engine oil in winter. In some severe cold regions, a special antifreeze oil should also be used. The oil filter should be changed at the same time as the oil change.

There is an impact, the oil is changed from 5w30 back to 5w20, the oil film formed by the oil inside the engine will become thinner, and the protective effect on the engine will be reduced.

The choice of oil viscosity needs to consider the degree of newness of the car, the engine parts of the new car have a small gap, you should choose a less viscous oil, and the vehicle with severe engine wear should choose a more viscous oil.

Oil labeling explained.

5W-30 or 5W-20 is the SAE standard viscosity value for motor oils.

W stands for winter, and the higher the number in front of it, the better the low temperature fluidity of the engine oil, which means the lower the ambient temperature available for use, in the cold start.

the better the protection of the engine; 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 number after w, the larger the number, the higher the viscosity, the better the sealing, the better the engine protection, and the more suitable for old cars; The lower the number, the lower the viscosity, the fuel saving, and at the same time the noise is low, making it suitable for new cars or naturally aspirated engines.

The number in front of w represents the freezing point, and 0w is 35; 5W is 30 ; 10W is 25 ; 15W is 20 ; 20w is 15; 25W is minus 10.

Summary. Can I change 5w30 oil back to 5w20? 5w30 engine oil can generally be changed to 5w20 engine oil.

The main difference between 5w30 oil and 5w20 oil is that the viscosity of the oil is different, 5w30 oil is a little more viscous than 5w20 oil, that is to say, it is slightly thicker, but the gap is not too big, and 5w30 oil and 5w20 oil are general-purpose engine oil, as long as the model is not too old, the number of kilometers is not a lot of cars can be universal!

Can I change 5w30 oil back to 5w20? 5w30 engine oil can generally be changed to 5w20 engine oil. The difference between 5w30 engine oil and Zheng 5w20 engine oil is that the viscosity of the engine oil is different, 5w30 engine oil is a little more viscous than 5w20 engine oil, that is to say, it is slightly thicker, but the gap is not too big, and 5w30 engine oil and 5w20 engine oil are all general-purpose engine oil, as long as the model is not too old, the number of kilometers is not very many cars can be universal!

Replace it with OW one 20 can not.

If the engine of your car is allowed to use a minimum of 20 viscosity oil, you can change back to 0w20 oil. Engine oil is something that every car owner needs to contact in the process of using the car, and the engine oil is called the blood of the engine of the Fa He change, if there is no oil in the engine, then Chan Kai judges that the engine is not able to transport Sun He Xing normally. Engine oil not only plays a lubricating role in the engine, but also plays a role in cleaning, sealing, buffering, rust prevention, and heat dissipation.

Summary. Hello dear, the range of use of 0w20 engine oil is to belong. Models with the latest China VI emission standards.

First, not all vehicles can be used, especially the old vehicles, if you use this oil, it is easy to have a lot of engine noise. Second, this oil is suitable for the most advanced turbocharged engines with direct injection in the cylinder, and the engines of the National VI emission standard. Third, especially the current Japanese models, this one uses this level of engine oil.

Fourth, the oil of the 0w20 engine can be replaced with 5w30, which is no problem. Dear, I wish you a happy family, if you have any other questions, you can continue to ask questions, I will wait for your reply.

Engine oil 5w-30YesChange to 5W-40, as long as it is the right oil for the vehicle.

Engine oil can lubricate and reduce wear, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning of the engine. It is known as the "blood" of automobiles. Engine oil is made up of two parts: base oil and additives.

Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.

Summary. It is not recommended to change the oil of 5w-30 to 0w-20. The oil of 0w20 is relatively thin, which can easily lead to insufficient oil pressure in the engine and increased wear.

Can I switch back to 5W-30 after using 5W-40 oil?

Hello, I am your exclusive service technician, attentive, attentive and careful to help you solve the problem of using the car If you use 5w-40 oil, you can change back to 5w-30 oil replacement, and if you return to 5w-30 oil, you should observe whether the engine sound is normal and whether the oil consumption is normal, if it is normal, you can always use 5w-30 oil.

Hello, five years old, I used to use 5w30, and now I have changed to 0w20, and it is not recommended to change the oil of 5w-30 to 0w-20. The oil of 0w20 is relatively thin, which can easily lead to insufficient oil pressure in the engine and increased wear.

The engine sound is OK, but it feels like the fuel consumption has increased.

In this case, it is not recommended to continue using it.

Semi-synthetic or fully synthetic for Japanese cars.

The fully synthetic one used by Japanese cars is better than the semi-synthetic one.

The user manual says that 0W20 is preferred, and it seems that you can't change the oil model casually.

Yes, the oil model cannot be used casually.

Then I'd better switch back to 5w20.

It should be changed back to 5w-30.

Changing the mineral oil is not also usable.

Replacing the mineral oil can also be used.
