What kind of engine oil is better for a car? Is the maintenance of well known brands reliable? Thank

It is not necessary to choose a well-known brand for maintenance, it is better to use a niche brand such as magic red engine oil for maintenance, and use high-end four types of PAO base oil, the driving experience is in place, and the power is kept silent. The main thing is that there are no fakes in engine oil, and there are too many fakes of domestic brands.

At present, the engine oil on the market can be simply divided into 1Mineral oil 2There are two kinds of synthetic oil, which can be divided into semi-synthetic engine oil and fully synthetic engine oil.

The biggest difference between mineral oil and synthetic oil is that synthetic oil can be used at a wider temperature, has a longer service life, and has a higher cost; The same oil film requirements can be achieved with a lower viscosity of synthetic oil, while mineral oil needs to be more dense than synthetic oil to achieve this requirement. In the same working environment, synthetic oil is more expensive because it has a much longer service life than mineral oil, but after comparing the number of oil changes, it is not much higher than mineral oil.

Engine oil is also lubricating oil, and the viscosity of lubricating oil is mostly marked by SAE and other grades, SAE is the abbreviation of the English "Society of Automotive Engineers". For example: SAE15W-40, SAE5W-40, "W" means winter (winter), the more the number in front of it, the better the low temperature fluidity of the 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.

SAE) Applicable ambient temperature (°C): 5W external low temperature resistance -30°C, 10W external low temperature resistance -25°C, 15W external low temperature resistance -20°C, 20W external low temperature resistance -15°C, 30W external high temperature resistance 30°C, 40W external high temperature resistance 40°C, 50W external high temperature resistance 50°C

In this way, the applicable external temperature range of 5W-40 oil is from -30°C to 40°C; The 10W-30 oil is suitable for external temperature range from -25°C to 30°C.

1. Try to use oil with higher API level, such as SL, SJ or CI-4, CH-4 and other engine oils, good engine oil can not only extend the service life of the engine, but also save fuel, especially the engine equipped with hydraulic system (such as VVT-I) and the engine of the turbocharger, must use high-performance engine oil, these oils are not only not easy to oxidize at high temperatures, and will not leave deposits in the precision parts of the engine, greatly prolonging the life of the engine. A fully synthetic motor oil is recommended.

2. The function of engine oil: alleviate friction and high temperature. As the name suggests, engine oil, also known as lubricating oil, can reduce the hard friction between the moving parts of the engine, ensure the flexible operation of the engine, reduce wear, and prolong the life of the engine.

Sealing effect. It is to seal the piston and cylinder of the engine, which can effectively prevent the cylinder string, ensure the effective power output of the engine, and improve the power of the vehicle.

One: mineral engine oil, if the mileage of the vehicle is not much, 5000 kilometers in half a year, can ensure timely maintenance. Or if the displacement is low, non-turbocharged, economical vehicles, mineral oil is more suitable for you, which can not only meet the requirements of vehicle lubrication performance, but also make the maintenance of the vehicle more economical.

Second: semi-synthetic engine oil, it is a mixture of mineral oil and fully synthetic engine oil in proportion, and then add additives to a mixed product, the performance is better than mineral oil, it is a very balanced product, good cost performance, 7500 kilometers of oil change cycle, most models can be selected.

Thirdly, fully synthetic motor oil, in low temperature fluidity is much better than mineral oil and semi-synthetic oil, in the same viscosity in winter, fully synthetic motor oil will start the vehicle faster, to reach the lubrication point faster. At high temperatures, fully synthetic oil because of better oxidation resistance, so its oil change cycle is much longer than semi-synthetic, mineral oil, basically more than 10,000 kilometers, although the cost is higher, but after comparing the number of oil changes and performance, it is not necessarily much higher than the first two oils.

Car maintenance must use fully synthetic engine oil, which can be used to replace it every 10,000 kilometers, and fully synthetic engine oil has the best performance in the engine oil category.

Whether it is a vehicle with a naturally aspirated engine or a vehicle with a turbocharged engine, it is best to use fully synthetic engine oil when maintaining, which can be maintained once every 10,000 kilometers, although the cost is more expensive, but the cost performance is very high.

If it is a turbocharged engine, give preference to fully synthetic engine oil, because in terms of high-temperature fluidity and viscosity, fully synthetic engine oil is much better than semi-synthetic.

No matter what kind of car, I recommend filling up with fully synthetic motor oil, because it is the most cost-effective, every 10,000 kilometers or once a year, and the lubricity is the best compared to others.

If your car is a turbocharged engine, it is recommended to use fully synthetic, and now a good engine oil ** is not very expensive, don't paint to save money.

The oil is definitely all synthetic. I have been using G T Magic Red engine oil in my car, and then I took it to the garage and asked them to help change it. Every time you change it, the power can be quickly raised.

This high-end fully synthetic motor oil is bought through official channels, in small bottles, and has anti-counterfeiting marks. The main reason for changing the oil is to buy it regularly, and don't buy fakes, otherwise you will damage the engine if you add it.

Car maintenance and oil change mainly. Combined with the performance of the car engine to change the oil, it does not mean that you can change it casually, some are to change the fully synthetic, and some may be semi-synthetic oil.

In fact, if you change the engine oil, it depends on the situation of the car, but generally speaking, it is better than the fully synthetic one, and the model of his engine oil, its viscosity, it is recommended that you must see clearly, your car is determined according to the gearbox, and it is not generalized.

Fully synthetic engine oil, preferably, change every 10,000 kilometers or 1 year.

Change to a well-known brand.

In terms of car maintenance, the engine oil is almost the same, and if you choose a big brand, you can have a better quality guarantee.

Fully synthetic motor oils, Mobil, Castrol, Shell can be, make sure it is**.

It is advisable to change the brand of fully synthetic motor oil, such as Mobil, Castrol.

Hello, fully synthetic motor oil will do.

It's a little better to change the fully synthetic oil. The internal lubrication of the engine is relatively good. And the sludge is reduced.

There are three main types of engine oil.

Each oil designation.

What kind of car are they suitable for? Which one is better? If you are a German car, Volkswagen and Audi.

The viscosity used in synthetic motor oil is basically 5w40, BMW.

0w40 is used more, and BMW uses 5w30 in synthetic engine oil. Generally, Mercedes-Benz new cars are 5w30, and the high power is mainly 5w40. Among American, Japanese, and Korean cars, 5w30 is basically the majority, and some of them require fully synthetic engine oil to be used from Subaru.

Mazda, Toyota, Honda.

0w20 for jeep, etc., or viscosity required by reference to the driver's manual. Among synthetic motor oils, 5w30 is a very cost-effective motor oil. The low-temperature starting oil volume and high-temperature oil film strength are almost close to 5w40, with a good sense of power and a certain degree of fuel saving.

German "gold", "lead" and "engine" titanium 5W30 are all in the synthetic engine oil, and the HTHS (high temperature and high shear viscosity) value is exceeded, which ensures higher oil film strength, reduces wear, and achieves better fuel-saving effect for large-displacement engines.

According to the use of the oil to decide whether it needs to be replaced, drop the oil on a piece of white paper, and then identify the oil use according to the oil color replacement judgment chart. With constant use, the oil will slowly deteriorate and be mixed with impurities.

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.

You can try, hopefully.

There are many factors to consider when choosing an auto oil, and there is no best, only the most suitable one:

1. There are many aspects to consider in the selection of engine oil: type, viscosity, temperature, vehicle age, brand, etc. Of course, brand and value have always been important attributes of goods;

2. The lubricating oil market is mixed, and it is generally difficult to distinguish the quality of engine oil based on appearance alone, and the principles of "you get what you pay for" and "brand represents quality" are also applicable to engine oil;

3. However, it should be noted that the choice of engine oil cannot be blindly good and expensive, and the suitable one that you can bear is the best. Of course, for base oils, it is definitely better to be synthetic than mineral;

Generally, it needs to be changed in three months or 5000 kilometers, and it can also be changed to Shell's all-season engine oil! When it is a good car, I change it to exclusive winter engine oil!

Mobil Total Synthetic is better.

It is good to replace the car with fully synthetic engine oil.

It's better to change the original engine oil.

The quality of the engine oil has little to do with the brand, because there are too many engine oils in China, and the bigger the brand, the less engine oil there is. Therefore, the most important thing in choosing an engine oil is quality and composition, not brand.

The brands on the above ** are all famous brands, but whether you can buy them really depends on your personal luck.

Although there is a flood of fake engine oil, some of the quality of the fake is still okay, although it is not as good as the real thing, but it does not affect the normal use of the vehicle, so the owner will not have much feeling.

China's fakes are so rampant that even the so-called identification methods may be various, and even fakes have their own identification methods, and many people can't tell what is real and what is fake.

Personally, it is recommended that it is best to buy or maintain it in a large fast insurance store or 4S store, because the larger stores should try it before purchasing to ensure the rights and interests of customers. Some conditions can be maintained in the 4S shop, although it is more expensive, but the heart is steady.

1. Fully synthetic oil is the best. Under normal conditions, fully synthetic motor oil can be changed every 10,000 km or every 12 months; Semi-synthetic motor oil can be changed every 7500 km or every 9 months.

The right oil for your car is the best, and you can add it to see what type of oil you need for your car. The quality of the engine oil of the big brands is no problem.

It is good to choose a big brand of regular engine oil for car maintenance, and there will be more Castrol engine oil on the market, so you can try it.

My car needs to be serviced, what brand of engine oil is better? I think I still need to consult the masters of the 4S shop.

Maintenance depends on your maintenance manual For general turbocharged engines, it is recommended to use full synthesis.

The principle of engine oil selection:

The viscosity of the engine oil recommended by the user manual is tested by comprehensively considering the high temperature protection of the engine oil and the low temperature fluidity, fuel consumption and other comprehensive factors, which is generally the most suitable for the engine, so the principle of choosing the engine oil is: refer to the user manual, try to use 0w, 5w fully synthetic engine oil, you can choose 5w in the south, and 0w can be used in the north!

The main difference between the different grades of closed residual engine oil is the viscosity of the oil.

In the oil label, the value in front of W indicates the viscosity of the oil at low temperature, the smaller the value, the lower the viscosity at low temperature, and the better the low temperature starting performance.

The value behind w indicates the viscosity of the oil at high temperature, the larger the value, the greater the viscosity at high temperature, and the better the protection performance of the engine under the high combustion temperature.

Semi-synthetic engine oil, it is a mineral oil and fully synthetic engine oil in proportion, and then add a mixed product of cracking cherry additive, the performance is better than mineral oil, it is a very balanced product, cost-effective, 7500 kilometers oil change cycle, most models can be selected.
