What kind of engine oil can be used for SUVs in vehicle maintenance to ensure the stability of the o

Semi-synthetic engine oil quality is not good performance is unstable, not suitable for SUVs, it is easy to damage the engine, at least extremely protective, the performance of fully synthetic engine oil is much better to alleviate the wear and tear caused by intense driving, and the power will be much stronger, but it is also graded, I Prado used to use extreme protection before, the power is good before 5000 kilometers, novice use OK, now I am used to driving like strong power on the PAO fully synthetic GT magic red engine oil imported from Germany, 12000 kilometers of power will be a little slightly reduced, It's no problem to run 15,000 for a while, and it's a pleasure to accelerate and run at high speeds and mountain roads.

The gasoline engines used in the Castrol engine series include Formula SLX, fully synthetic oil SAE OW 30, and APISJ CF grade, which is a new generation of products specially developed for European and Japanese automobiles, which has four main characteristics: (1) OW viscosity is extremely fluid, which can provide the fastest protection when starting the car; (2) The unique viscosity index improver can still maintain the thickness of the oil film at high temperature, so the use of fully synthetic engine oil can ensure the stability of the oil film. Because the fully synthetic engine oil is the highest grade engine oil on the market, its base oil is a lubricating fluid composed of macromolecules dispersed from gas or natural gas.

Compared with mineral oil, it uses the best ingredients, which are chemically reacted and artificially controlled to achieve a near-perfect molecular state. Fully synthetic motor oil is used at a wider temperature, has stronger oxidation resistance, and has better physical stability at high temperatures, and its service life is generally more than twice that of mineral oil. For sports or high-performance vehicles, fully synthetic engine oil is also the first choice, which can not only ensure oil film stability during intense driving, but also reduce engine wear at low temperature cold starts.

In addition, if your car has a short annual mileage and long service intervals, you can also consider choosing a fully synthetic motor oil.

First of all, it is necessary to ensure that it is the best engine oil, and secondly, no matter what brand of engine oil, the viscosity should match the use of the engine, and the label can not be used wrongly, the viscosity is too high will increase the resistance of the engine operation, increase fuel consumption, the viscosity is too low, the sealing is reduced, and the power is insufficient. Therefore, it is necessary to change the oil according to the viscosity of the engine oil recommended by the manufacturer.

The viscosity is right, and then according to the engine type to choose the oil, the displacement of the self-priming engine, semi-synthetic oil can be fully competent, but turbocharged models, must use fully synthetic oil, when the supercharged parts begin to work at the moment, the engine torque will increase exponentially, at this time the oil film covering the various friction parts of the engine to withstand several times higher shear force than before, fully synthetic oil can meet the requirements of high oil film strength.

Large displacement performance cars, sports cars, SUVs, due to the weight of the body, high engine power, its working temperature, oil temperature is higher than ordinary cars, the better high-temperature sports performance of fully synthetic engine oil can not only ensure the stability of the oil film in the intense driving, the advantage of low temperature start can also ensure that these expensive engines reduce the wear of cold start. Hope to adopt.

It is good for the car with a good oil.

1. Engine oil, that is, engine lubricating oil, English name: engine oil. The density is about to lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine.

Known as a car"Blood"，。The engine is the heart of the car, and there are many metal surfaces in the engine that rub against each other, and these parts move fast, the environment is poor, and the operating temperature can reach 400°C to 600°C. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life.

2. The engine oil on the market can be simply divided into two types: mineral oil and synthetic oil due to its different base oils (vegetable oil is not counted due to the scarcity of production). Synthetic oil is divided into: fully synthetic and semi-synthetic. Fully synthetic motor oil is of the highest grade.

3. Engine oil is composed 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.

1. The sealing effect is reduced.

The proper viscosity of high-quality engine oil can effectively plug the gap between the cylinder block and the piston to prevent gas leakage. If the engine oil is not changed for a long time, the oil will be watery, lose its sealing effect, and contain a large number of metal chips and gels, which will seriously affect the service life and stable operation of the automobile engine.

2. The cooling effect is reduced.

The heat absorption and thermal conductivity of oil are much higher than that of water, and if the oil deteriorates severely, the heat dissipation function will be greatly reduced.

3. The lubrication effect is reduced.

The viscosity of the oil gives it strong adhesion and can form a protective film between parts such as gears and shafts, making them run smoothly and reduce wear. Spoiled motor oil basically loses this effect.

4. The cleaning effect is reduced.

Friction between metal parts can produce debris, and combustion can produce impurities such as carbon deposits. If the oil is not changed for a long time, these impurities will be deposited between the parts of the engine, causing harm to the operation of the engine.

5. Serious direct burning of the engine (oil consumption).

Hello, if the vehicle mileage is short, basically 5000 kilometers in the first half of the year, can do timely maintenance and oil change, belongs to a small displacement, non-turbocharged economic vehicles, it is recommended to use mineral oil, because these models are weak, the power of the oil attenuation is not strong, and the impact on the driving experience is not great. From the cost point of view, such as practice cars, low-quality second-hand cars, online car-hailing, taxis and other operating passenger cars, mineral oil is more suitable, which can not only meet the requirements of vehicle lubrication performance, but also reduce the cost of car maintenance, but the important thing is to say again, timely maintenance.

The applicability of semi-synthetic engine oil is more extensive, for non-low-end naturally aspirated vehicles, semi-synthetic engine oil is more suitable, better lubrication performance, longer oil change interval, if the majority of car owners feel that full synthesis is too expensive, and want to add some good oil to the car, you may wish to try semi-synthetic it. Of course, in harsh environments or long-term short-distance driving, it is necessary to appropriately shorten the mileage of oil change, all in order to extend the service life of your car, everyone can grasp it yourself.

Fully synthetic engine oil is suitable for a wide range of models, considering the cost of maintenance, many car owners choose semi-synthetic engine oil, but the following models must use full synthetic engine oil: turbocharged, sports cars, large displacement cars or SUVs.

First: 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. Hope to adopt.

1. Mineral oil: Mineral oil is directly extracted from the **, and the oil that has not been artificially increased and changed is called mineral oil, and it is also the cheapest engine oil, and the grade is generally below SJ, which is generally only suitable for low-grade cars or some new cars.

2. Semi-synthetic engine oil: There are two main types of semi-synthetic engine oil, one is obtained after hydrocracking and purification of mineral oil, and the other is directly blended from mineral oil and fully synthetic engine oil by a certain proportion, but no matter which way, semi-synthetic engine oil has a greater improvement in performance than mineral oil, and it is also relatively moderate, which is more suitable for low-end and naturally aspirated engine models.

3. Fully synthetic oil: The constituent oil is made by artificial methods, including cracking and polymerization, which is called constituent oil. If the base oil used to produce the engine oil is all made from this type of constituent oil, it is called a fully composed engine oil.

It has good resistance to high temperature volatilization and deposition, and is suitable for high-temperature, high-speed and high-compression ratio engines, such as turbocharged engines. **Also the most expensive of the three types of motor oil.

Shell, Castrol, BP, Mobil, Esso and other old British and American motor oil products have long been household names, especially in the high-end market, occupying an absolute advantage, and the giants are also on this basis, constantly supplementing mid-range products, and extending the product front. Great Wall, Kunlun and Uni-President are the representatives of domestic engine oil, and the quality is also guaranteed.

Castrol Magnet is Castrol's breakthrough technology in the field of motor oils. Castrol's main gasoline engine oil products are: Champion Fully Synthetic Engine Oil, Magnetic Engine Oil, Jiahu Engine Oil and Power Protection Engine Oil.

Jiahu oil is an upgraded version of the original Castrol Gold luxury oil, which adds "active synthetic protective molecules" to maintain lubrication at low temperatures, and also provides stronger rust protection and anti-wear effect.

The choice of oil should be based on the requirements of the engine, and it is not necessary to use too high grade oil on a less demanding engine, nor can you use a lower grade oil on a more demanding engine. 2. Multi-grade oil should be selected as much as possible, because 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 brand-name engine oil is quite good, and it is much lower than that of similar imported products, so 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 path 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.

Special engine oil may not be suitable for your car Many brand car factories have a matching special car oil, although it is more expensive than the general engine oil, but many car owners think that the special engine oil is the most suitable for their vehicle requirements, so they still insist on using this engine oil. But after adding special engine oil, the vehicle often has problems, why is this? According to industry insiders, special car oil is not necessarily suitable for your car.

The automobile manufacturer itself does not have a factory specializing in the production of automobile engine oil, it only entrusts the special engine oil of the brand car to a certain manufacturer according to a certain standard, and does not monitor the production of engine oil. The oil standards of some internationally renowned brand automobile manufacturers are formulated according to the level of developed countries. In addition, the oil for the car also needs to be based on the age of the car and the condition of the engine and the regional situation, only a few specifications of special engine oil of course can not meet the requirements of a variety of vehicle conditions and a variety of regional conditions.

Good and well-known are: Mobil, Shell.

1. Castrol, Compton, etc. In winter, the number 30 and 40 are common in all seasons, and the number 50 is for summer.

Look at car maintenance, there are instructions on what kind of oil to use, the right number to sit, if you ask **, about 100,000 cars, about 200 yuan of four liters of oil. About 200,000 yuan, about 300 yuan of semi-synthetic, or fully synthetic engine oil, more than 300,000 yuan, more than 400 yuan of pure synthesis,

Car maintenance, general basic maintenance includes oil and filter changes. As for which engine oil to choose, in fact, as long as you choose a top-ranked brand engine oil that meets your model level and viscosity, you can do it. First of all, you have to depend on the actual situation of your car, for example, the use of semi-synthetic engine oil is enough for the general compact model, while the oil requirements for turbocharged models are relatively high.

If the vehicle mileage is short, basically 5000 kilometers in the first half of the year, can be timely maintenance and oil change, belongs to a small displacement, non-turbocharged economic vehicles, it is recommended to use mineral oil, because these models are weak, the power reduction formed by oil attenuation is not strong, and the impact on driving experience is not great. From the cost point of view, such as practice cars, low-quality second-hand cars, online car-hailing, taxis and other operating passenger cars, mineral oil is more suitable, which can not only meet the requirements of vehicle lubrication performance, but also reduce the cost of car maintenance.

Normally, fully synthetic engine oil is suitable for a wide range of models, considering the cost of maintenance, many car owners choose semi-synthetic engine oil, but the following models must use fully synthetic engine oil: turbocharged, sports cars, large displacement cars or SUVs.

When the supercharged parts start to work, the engine torque will increase exponentially, and the oil film covering the various friction parts of the engine must withstand several times higher shear force than before, so that the fully synthetic oil can meet the requirements of high oil film strength.

Large displacement performance cars, sports cars, SUVs, due to the weight of the body, high engine power, its working temperature, oil temperature is higher than ordinary cars, the better high-temperature sports performance of fully synthetic engine oil can not only ensure the stability of the oil film in the intense driving, the advantage of low temperature start can also ensure that these expensive engines reduce the wear of cold start.
