How to choose the right car oil?

1. Selection of oil grade:

This is the first step in the selection of car oil, if the oil is not selected properly, there will be abnormal phenomena when in use, and even cause abnormal wear, the higher the effective pressure of the engine cylinder, the higher the engine speed, the higher the requirements for the oil grade. When choosing a car oil, you can choose it according to the car's instruction manual. If you don't have the same grade of oil, you can choose a higher grade of oil.

2. Selection of viscosity:

The choice of viscosity of automobile engine 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.

Attached: Misunderstandings of oil replacement:

1. Change the oil again when it turns black

This is a lot of car owners to judge the way to change the oil, in fact, this is not a very good way, if you find that the car's oil has turned black, it means that the oil has been seriously deteriorated, so this is not a good way to judge, you can change it reasonably according to the marks on the car manual.

2. Only add but not change:

This is also one of the more common phenomena in the daily oil replacement, the oil of the car will produce some impurities after a long period of use, if only add without changing, it is easy to affect the lubrication effect of the oil.

Specialty car oils don't necessarily work for your car. Oiling your car also depends on the age of the car and the condition of the engine, as well as the regional conditions.

First of all, it is necessary to ensure the best engine oil, and secondly, no matter what brand of oil, the viscosity should match the use of the engine, the label can not be used wrong, the viscosity is too large to increase the resistance of the engine operation, increase fuel consumption, the viscosity is too small, the sealing decreases, and the power is insufficient, so the oil should be replaced according to the oil viscosity recommended by the manufacturer.

It's better to use fully synthetic engine oil, the GT Magic Red engine oil used by my Highlander, four types of PAO base oil, a niche brand, but the oil is particularly good, and it is generally used by some high-end car owners.

The fully synthetic engine oil I used before feels quite average, and the GT Magic Red engine oil I changed is much longer than the original engine oil, and it is more than 13,000 kilometers to replace it twice.

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.

It is best to choose high-quality engine oil, I usually drive more fiercely and buy GT Magic Red engine oil power to go to the outside auto repair shop to do, this oil quality is very good, it is an additive of liquid molybdenum, anti-wear protection ability is very good, it can reduce the friction of the engine, reduce the noise of the engine, and the attenuation period is as long as 10,000 kilometers, I am 15,000 kilometers to change, easy to maintain.

For the selection of automobile engine oil, it is necessary to choose the engine oil with suitable performance according to your own vehicle, and it is good to choose semi-synthetic engine oil for general vehicles.

I am currently using GT Magic Red engine oil, four types of PAO base oil, ultra-high temperature shear HTS, at high speeds, the power is still sufficient, will not thin out and lose lubricity, and it contains liquid molybdenum, the biggest effect of this additive is anti-wear, can reduce the wear rate by more than 40%, thereby improving the power output. Now the car is very powerful, and it drives much better than the original.

The original engine oil is more general, and the engine is louder and not easy to use. I haven't used it since Sanbao, and now I've changed it to GT Magic Red engine oil, and I feel that the whole driving feeling is different when I just put it on, the power is enough to throttle and the throttle is light, and the engine runs without sound at all, which has improved a lot of small problems before.

How to choose the right car oil? I think if it's 77, I'll change it if I haven't run 200km. I will choose the American service popularity, because the art popularity tour is really good quality and has a good guarantee for the engine.

How to choose the right system for the first car engine oil to try out the practical technology of the person? Professional people. Who knows which oil ratio to choose. Others are unlikely to have an option.

The importance of motor oil to the car is self-evident, without it, the car engine will suffer serious damage, making it difficult for the car to move an inch. Engine oil is not only responsible for lubrication, it also has the functions of cooling, cleaning, vibration damping, sealing, etc. At present, the oil grades on the market are intricate, often so that car owners do not know how to choose, in fact, there are only two main indicators of engine oil, figure out the specific meaning, on the line.

Viscosity indicator. According to the SAE method, there are 6 types of oil for winter, 5 types of oil for summer, and 16 kinds of general oil for winter and summer.

Winter oil grades: OW, 5W, 10W, 15W, 20W, 25W. The symbol W represents winter, 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.

Summer oil grade, 60. The higher the number, the greater its viscosity and the higher the applicable maximum temperature.

Winter and summer general oil grade: 5w w w w w The smaller the number for the winter portion and the larger the number for the summer portion, the larger the applicable temperature range.

Quality indicators. According to the API quality classification, engine oil is divided into gasoline engine oil series (i.e., S series) and diesel engine oil system (i.e., C series), and the oil products of each series are arranged in alphabetical order (A, B, C, D, E, F), and are divided into several grades, and the lower the letter ranking, the higher the grade.

Selection method. The marking on the outer packaging of engine oil currently sold on the market consists of two parts: SAE viscosity classification level and API quality classification level. It usually starts with SAE and is followed by a viscosity code; The engine oil label classified by API quality generally omits the API and directly marks the quality grade code.

For example, the designation SAE10WSD indicates a winter gasoline engine oil with a viscosity classification of SAE10W and a quality level of API SD; The designation SAE30SD indicates the viscosity classification SAE30, and the quality grade is APE SD for summer gasoline engine oil; The label is SAE10W 30SD (or SAE10W 30SD), which indicates that the viscosity classification is to meet both SAE10W and SAE30 winter and summer general purpose gasoline engine oil, and its quality grade is API SD grade.

When choosing a motor oil, fans can combine the local maximum and minimum temperatures and refer to the car's "User Manual". If you choose an oil that is too viscous, it will increase the resistance to movement and consume engine power; If you choose an oil with too little viscosity, the lubrication quality cannot be guaranteed, and it will aggravate the wear of the engine. For engines that have been seriously worn and the gaps between the fittings are large, a higher viscosity oil can be used to strengthen the sealing performance of the fittings.

1.For common Japanese and American cars, such as: Toyota, Honda, Mazda, Ford, the design of the engine is more precise, suitable for those with good cleanliness and not very high viscosity (about 20).

On the market, most Japanese cars are more suitable for 0w w20 type of engine oil. Also heard.

2.For German cars, most of them are turbocharged engines, and the operating temperature and pressure of the turbo machine are significantly higher than that of naturally aspirated engines, and the turbo speed is very high. Moreover.

3.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, even.

The engine oil used in various cars is different!!

Just add the number according to the regulations of the original car. Brands need no introduction.

Car oil is a kind of lubricant, you can choose a regular manufacturer, choose a big brand, so that the quality is guaranteed, and the use effect is better.

1. During the running-in period, the engine oil is generally selected with low viscosity, and excellent wear resistance is required.

It is recommended to use relatively thin engine oil for cars within a kilometer.

After a few kilometers, slowly increase the viscosity of the oil.

4. Replace the 40 viscosity in summer and use the product with 30 viscosity in winter, which is convenient to provide better protection for the vehicle in different temperature environments.

As the vehicle ages, you need to consider your own driving habits and the performance requirements of the car to adjust the oil products used. The high viscosity of the engine oil can give more protection to the engine parts, which is suitable for the engine running at high temperature for a long time, and fills the gap between the engine due to the long-term virtual and long-term operation. A lower viscosity oil may be more fuel-efficient, with faster engine revs and more responsive acceleration.
