How to choose engine oil for family cars and what kind of oil is better?

At present, the three major engine oil brands of Mobil, Shell and Castrol are very good, and the overall performance of these three brands of engine oil is good, and each has special characteristics, such as Shell engine oil, which focuses on cleaning performance; Mobil motor oils focus on the longevity of motor oils; Castrol has a strong oil film and good engine cold protection performance.

The use of these oil groups also occupy the majority of the population, oil is very important in the process of maintaining the vehicle, the use of a good suitable oil can better protect the engine, protect the vehicle, and prolong its service life.

1 It depends on the purpose of your car.

2 usually have a high car usage rate.

3. Your vehicle leaves the factory and requires the number of the engine oil (the engine is required to add the oil on the cover), 4. How many kilometers are usually maintained.

You can choose from the above, the engine oil brand is more famous for Shell, Mobil, Castrol, Unified Lubricating Oil, Great Wall is more common, these brands are divided into minerals, semi-synthetic, fully synthetic, engine oil is not the more expensive the better, choose the right one for your own vehicle, it is recommended to use fully synthetic, long-term use of the engine protection is better, **civilians are recommended to unify lubricating oil, **low quality is also good.

Family cars are basically used for daily commuting, the driving distance is short, and the frequency of use is not high, so the choice of engine oil should choose low viscosity, anti-wear, fully synthetic engine oil, replacement cycle of 10,000 kilometers or a year, the engine protection is also better than mineral engine oil, Mobil, Castrol, Shell genuine engine oil can be used with confidence, do not choose those so-called German quality, European technology, German high-quality biomass engine oil, buy cheap and expensive!

Consult the vehicle manual, according to the oil model specified in the manual, generally Japanese cars use 0w or 5w20 oil, German cars use 0w or 5w40 oil.

In fact, whether it is a self-priming engine or a turbocharged engine, we recommend that you add fully synthetic engine oil, in fact, you calculate, fully synthetic engine oil is not much more expensive at all, and it can bring better protection to the engine, and it can also allow you to maintain it less once. Hope!

It is recommended to choose the manufacturer Amway as much as possible.

of the brand. Because although the major brands of lubricating oil are similar, but in fact there is still a gap, some emphasize wear resistance, some pay attention to heat dissipation, and some have a better cleaning effect. My car is a domestic car.

The factory uses Kunlun lubricating oil, and there is no problem.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

If the engine is the heart of the car, then the oil is the blood of the car, the oil plays a role in lubrication and cleaning of the engine and other parts, the core of maintenance is actually the oil replacement, it is recommended that you add fully synthetic oil.

It is recommended that joint ventures or domestic fully synthetic motor oils are the most suitable motor oil for family cars so far.

Before I would look at the brand (big brand), now as long as it is true, the current use of domestic engine oil, PetroChina's Kunlun lubricating oil, the effect is good.

The method of choosing the right engine oil for automobile engine oil is as follows:

1. Select engine oil according to the engine type. If you are a turbocharged engine, it is recommended to choose a fully synthetic or semi-synthetic engine oil, which is more conducive to engine heat dissipation.

2. Select engine oil according to the vehicle. Mini cars and scooters below 100,000 yuan are recommended to use mineral oil or semi-synthetic engine oil. 10-20 range family car is recommended to choose semi-synthetic or fully synthetic motor oil, etc.

3. Choose the engine oil according to your car environment. If you are using a car in extreme environments, such as Heihe and Qiqihar in winter, Hainan, Turpan in summer, etc., it is recommended to use fully synthetic engine oil.

4. Select engine oil according to displacement. If you are a small-displacement self-priming engine (less than that, and have power requirements, it is recommended to choose fully synthetic or semi-synthetic engine oil, because mineral oil has a high viscosity and will affect the power of the vehicle.

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.

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. Based on the characteristics of multi-grade oils.

In the process of use, there may be premature blackening, and the oil pressure is smaller than that of ordinary engine oil, which is normal.

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.

I used to use semi-synthetic engine oil, the power of the car was too poor, and it didn't last long, it declined after driving 3,000 kilometers, and it was replaced after 5,000 kilometers. That's enough for me to run for more than two or three months. Later, I changed the PAO engine oil with a longer maintenance cycle, and now I use the G T magic red engine oil imported from Germany, the power state of the car is particularly good, the power can be maintained for more than 10,000 kilometers, much better than the semi-synthetic engine oil power, the driving feeling of the car is completely different, and the power of the car is much better.

The throttle is very smooth, and now it is more than enough to change the oil more than once in half a year, which is particularly convenient.

You can go to a 4S shop or an auto repair shop. It is better to change to fully synthetic engine oil than to change to four types of PAO engine oil, 15,000 kilometers to change it once, I have been using G T magic red engine oil is PAO, the power increase is also better than using semi-synthetic engine oil, off-road to climb the acceleration are a lot stronger.

The oil is definitely all synthetic. I have been using G T Magic Red on my car, and then I took it to the auto repair shop 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.

Generally, when buying a car, it is recommended to use a gasoline model, which is generally 92.

Q5 used to be in the 4S shop with extreme protection, Jin Mei Mobil 7500 kilometers to change once, the power is OK, but the maintenance cost is quite expensive, these two years have been used G T magic red oil, are bought by themselves, 15000 kilometers of maintenance, is currently used in the most cost-effective synthetic engine oil in the most cost-effective and bought their own oil to the auto repair shop maintenance than the 4S shop is more cost-effective.

In fact, our choice of engine oil is not to choose the most expensive, but should be based on the characteristics of our car engine, and our usual driving habits, to choose the right oil is the most correct. Engine oil is equivalent to human blood for a car, to put it simply, there is no way to drive a car without oil. Engine oil is mainly composed of two parts: base oil and additives, and the quality of the base oil determines the long-term performance of the oil; Additives can improve the lubricating properties of the oil.

The number of the oil.

Semi-synthetic oil and fully synthetic oil have their own number, which many car owners will notice when changing the oil, such as 5w-30 or 5w-40. These numbers represent oils with different frost resistance and high temperature viscosity. The number in front of the letter W indicates the fluidity of the oil at low temperatures, which is commonly known as the freezing point.

This number minus 35 indicates the lowest temperature at which the engine oil can be started, and the number after w indicates the high temperature viscosity of this engine oil, the higher the number, the greater the viscosity.

Choose according to the car series.

Before choosing engine oil, we must first figure out what kind of car our car is, specifically European, Japanese, American or something, because the engine of different types of cars has obvious differences in design, so the engine oil used is not the same. For example, we all know that American cars, the engine is more precise, the gap between parts is smaller, and the oil of 5w-30 is the most suitable. As for German cars, turbocharging technology is usually used, and the gap will be relatively large, and it will be relatively better to choose 5W-40.

Japanese and Korean cars will use more viscosity oils, such as: SAE 0W W W W-30; The choice of engine oil for domestic cars is not much different from that of Japanese cars, after all, many domestic cars are imitations of Japanese car engines, and even directly used Mitsubishi or General Motors engines.

Different models are available depending on the age of the vehicle.

Each car will be equipped with a maintenance manual as standard, referring to the maintenance manual on the car, new cars usually choose a slightly lower viscosity oil, as the car ages, slowly choose a slightly more viscous oil, because the older car engine wear will be more serious, choose a relatively higher viscosity oil.

Choose a model according to the season.

Knowing that the season is different, the choice of engine oil is not the same Generally, within the reasonable range specified in the driving manual, the engine oil suitable for use in winter is the first thing to look at the low temperature viscosity grade to ensure that the low temperature performance of our engine oil is very good. We will recommend the engine oil with better fluidity, that is, 5w-30, and try to choose the smaller value of the viscosity grade in summer, so that the high temperature viscosity of our engine oil is as low as possible. It is recommended to use engine oil with higher viscosity, that is, 5w-40.

In this way, the oil viscosity will not be high due to the low temperature, and the cold start performance will be relatively poor. However, in some areas, 5W-30 and 5W-40 engine oil can be used, so don't worry too much!

Finally, according to everyone's different driving habits, you can also choose the engine oil, if you are a friend who pursues speed, you usually drive the engine speed may be very high, then we can choose a fully synthetic engine oil.

1.The choice of oil grade: This is the first step in the selection of automobile engine oil, if the oil label is not selected properly, there will be abnormal phenomena when in use, and even abnormal wear and tear, the higher the effective pressure of the engine cylinder, the higher the engine speed, the higher the requirements for the oil grade.

2.The choice of viscosity: The choice of viscosity of automobile oil needs to be determined according to the driving environment, you can choose the multi-grade engine oil used in winter and summer, which will make the owner more worry-free, for the southern region where the temperature is relatively stable, under the premise of ensuring the normal lubrication of the engine, the viscosity of the engine oil should be as small as possible.

When you start a new car, you can choose a lower viscosity of the oil, which can generally be implemented in accordance with the original factory standards. 10w km old car, try to have a higher viscosity level. Especially for cars that burn engine oil, use anti-wear agents at the same time as the viscosity is high.

Because the viscosity of the oil changes with temperature, the viscosity thickens in winter and thins in summer. Therefore, it is recommended to choose an oil with a slightly higher viscosity in very hot areas. In the colder season, a thinner oil can be used.

In fact, it is more appropriate to choose a fully synthetic engine oil for automobile oil, although it is more expensive, but the running-in performance is really good.
