What is the best engine oil for old cars? What is the best engine oil for a car?

Hello subject, I use GT Magic Red engine oil, because I think that the big brand engine oil I used before is not as good as Magic Red engine oil, and they are all PAO three types of base oil fully synthetic engine oil, and Magic Red engine oil is a PAO four types of base oil fully synthetic engine oil, good comprehensive performance, ** is also reasonable, but also the most perfect engine oil used at present, if it helps, look forward to, thank you.

The use of synthetic engine oil in old vehicles to burn engine oil is objective, but there is no need to over-interpret, most of them will not cause a surge in oil consumption, and it is only obvious when the cylinder barrel is worn very seriously.

Old cars should pay attention to the cleaning and protection performance of engine oil, on the one hand, to prevent excessive carbon deposit, on the other hand, to better protect the operation of engine parts. And the old car will inevitably have the problem of insufficient power after driving for a long time, change the oil to a better point, improve the viscosity of the oil, and basically solve the problem.

What is the best engine oil for a car? There are many brands of engine oil, such as: Castrol, Shell, Mobil, Great Wall, Total, Foss Kunlun and so on, among which Shell, Mobil, Castrol are very good.

When it comes to practicality, Castrol is practical. The best is the one that suits your car.

The principle of choosing engine oil for automobiles:

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, and 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 different grades of motor 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 after 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 at high temperature.

If the car was manufactured after 2000 and is a Japanese or American car, then use the 10W W 30 or 5W 40 viscosity grade for all seasons, and the European car should use 5W W 40 or 15W 40.

In the concept of some old mechanics or old drivers, the higher the viscosity of the engine oil used in summer, the better, and then change to a less viscous engine oil when used in winter, but this view is no longer in line with the requirements of automobile development.

For example, at the service stations of Nissan, Toyota, and Honda, no matter spring, summer, autumn and winter, only one viscosity level engine oil is being maintained--- 10W 30, GM Buick is 5W W 30, and Shanghai Volkswagen's Passat and Polo are 5W 40. Dongfeng Citroen is 10w 40. These viscosity grades of motor oil, although low viscosity, do not cause damage to the vehicle.

Because the viscosity is small, the frictional resistance when the engine is doing work becomes smaller, the friction coefficient becomes smaller, the fuel consumption of the engine becomes less, and the horsepower becomes stronger; Because the viscosity is small, the flow rate is fast, the flow rate is fast, the heat dissipation is fast, the heat dissipation is fast, the condition of the engine will be kept in the best condition, the heat dissipation is fast, and the temperature of the oil itself will be reduced, and the service life will be prolonged.

Tips for choosing engine oil.

1. Choose the type.

Engine oils are divided into mineral oils, semi-synthetic oils and fully synthetic oils, which are divided according to the base oil of the engine oil, and the performance of these three types of engine oils is enhanced in turn.

If you don't have a bad money, it is recommended to use fully synthetic engine oil, which not only has a better protection effect on the engine, but also greatly delays the decay time of oil performance and engine power.

2. Select the label.

Each barrel of oil will be marked with the number of the oil, such as SN 0W-20.

S means for gasoline engine, N stands for the quality grade of the engine oil, the further back the letter, the higher the quality level, the highest is N.

0w-20 represents the viscosity of the oil, w is the abbreviation of winter in English, and the number in front of w is simply understood as the minimum temperature at which the oil loses its fluidity.

The conversion of this temperature is -35 degrees Celsius to the number before w, and the result is the minimum temperature at which the oil loses its fluidity.

For example, 0w: 0-35=-35 degrees Celsius, 5w: 5-35=-30 degrees Celsius, if the local temperature is lower than this temperature, the oil will not flow.

The lower the number, the stronger the engine's ability to start at low temperatures and the stronger its low temperature protection ability. The number after w indicates the viscosity of the oil, and the higher the value, the more viscous it is.

The simple understanding of viscosity is the high temperature protection ability index, the higher the viscosity, the stronger the high temperature protection ability. However, the viscosity is high and the fluidity is also small, which will increase fuel consumption. Therefore, the main consideration of each car is whether to fuel consumption or protection.

Most car owners can use the original engine oil, but older cars with higher mileage or often drive at high speeds, you can choose a slightly thicker engine oil.

The above content reference: Phoenix - how to choose the right engine oil? It is enough to look at these 3 points.

The above content reference: phoenix.com - what kind of car should use what kind of engine oil.

Depending on your car, is it necessary to be fully synthetic? Semi-synthetics are already very responsible for your own car! If you want to use a full synthesis of 10,000 kilometers, it is better to exchange 5000-7500 for a semi-synthesis.

The quality of 5W-40 with magnetic protection and blue shell is completely sufficient.

The previous 17w km of the lion run, all the magnetic protection, at the beginning of 5000 kilometers a change, and then 7500 a change, now think about it is a bit of a waste. For your reference.

High mileage oil.

It can also solve some other problems, when the tightness of the engine valve is compromised, the conditioner of the high mileage oil can help reduce the oil seeping into these parts, and the oil usually has a lower volatilization, which means that it is more friendly to the car with the phenomenon of burning oil; Usually, after two changes to the high-mileage oil, the burning of the engine oil even disappears.

Many people think that high mileage oil refers to the longer life of the oil, so it is not right, the old driver said, the high mileage here refers to the age of the car, with the advancement of time, the rubber components inside the power unit will lose some chemical components, which makes them more fragile, and even small cracks, which will lead to the leakage of oil in the engine.

High-mileage oils are equipped with seal conditioners that react with elastomers such as rubber to replenish lost chemicals, making the rubber softer and expanding slightly to restore elasticity and prevent oil leakage.

Key features:

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 to 600 meters. The new technology transforms natural gas into crystal-pure, fully synthetic base oils, on which is added with unique powered cleaning technology to create lubricants with superior cleaning protection.

Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life. The engine oil on the market can be 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 further divided into:

Fully synthetic and semi-synthetic.

Lubricating oil base oils are mainly divided into two categories: mineral base oils and synthetic base oils. Mineral base oils are used in a wide range of applications in large quantities (about 95% or more), but some applications require the use of synthetic base stock blends.

If you are an old car, you can simply use an oil with a viscosity number, such as 5w-30, 40, 10w-30, 40 and other grades. The viscosity of the engine oil is low, and it is easy to burn the engine oil seriously and increase the problem of oil leakage.

The car has been driven for ten years, and the engine has not burned oil, which means that the car is well maintained.

As long as it is a regular manufacturer's engine oil, it meets the national standards, and it is okay to choose a joint venture brand or a domestic brand engine oil. It is recommended to change the fully synthetic engine oil, the maintenance interval is long, and it is recommended to choose 5w-40 engine oil for ten years of car, and it is recommended to change the engine oil of 0w-40 if it is in the Northeast.

It's simple. First, engine oil is divided into mineral oil, semi-synthetic oil, and fully synthetic oil. Fully synthetic motor oils are best to use. Second, the oil grade is sorted alphabetically from SA, and the SN grade is the best. Third, the oil model 0w-40, viscosity, is low temperature fluidity and high temperature fluidity.

That uses high viscosity oil, four-zero oil, 5w four-zero.

Old cars should generally use a higher viscosity of the lubricating oil, because the engine is more or less wearable, with a large viscosity of the lubricating oil can play a certain sealing role, my old car used to use Kim Mobil 5W40 lubricating oil, but after using it I feel that the fuel consumption is a bit high, and then I changed the GT magic red 0w40 lubricating oil, the fuel consumption is also lower, very easy to use!

For older cars, it is recommended to use a higher viscosity oil.

When maintaining the vehicle, the staff often asks whether to use fully synthetic engine oil or semi-synthetic engine oil, and many people only know that fully synthetic engine oil is better and more expensive. But if you talk about the specific difference between fully synthetic engine oil and semi-synthetic engine oil, or what type of engine oil is used for many kilometers of vehicles, I'm afraid many people don't know, today we will find out.

There are two types of synthetic motor oils: semi-synthetic and fully synthetic. Semi-synthetic motor oils are a mixture of conventional mineral and synthetic motor oils.

Due to the addition of synthetic base oils, it has higher performance and better engine protection than conventional mineral oils. Fully synthetic motor oils contain almost no conventional lubricants. Rather, it is a mixture of additives and synthetic base oils, resulting in higher lubricant performance and excellent engine protection.

Synthetic base oils and additives help prevent wear, keep engines clean, increase lubricant fluidity at low temperatures and viscosity index at high temperatures, prevent rust and reduce friction. In addition, because fully synthetic motor oils are more resistant to wear, they last longer. The fully synthetic engine oil also adds a lot of oil additives to increase the comprehensive performance of the oil.

Through the above analysis, it is not difficult to see that in terms of comprehensive performance, fully synthetic motor oil is completely superior to semi-synthetic motor oil. Therefore, it is generally recommended to replace the fully synthetic engine oil for vehicles with kilometers within 100,000 kilometers, cars with turbochargers, and engines with direct injection in the cylinder. For cars that have been using semi-synthetic engine oil for more than 100,000 kilometers, it is not recommended to replace the fully synthetic engine oil, because the sealing of the engine lubrication system of the old car is relatively poor, the viscosity of the fully synthetic engine oil is low, and the good fluidity is easy to cause oil leakage.

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.
