Car Maintenance Knowledge EncyclopediaAbout Which engine oil is better to start in the morning?

To improve the start of the car, of course, it is best to use high-quality fully synthetic motor oil. My car used to use the original engine oil, I really can't complain, the ignition is super slow in the morning, and the sound is not quite right after starting. In the past few years, GT Magic Red has been changed, and the quality is indeed different.

After changing the mute and power are very good, last year it was cold and did not have to worry about the morning start problem, the throttle is not meaty, the power is enough, the response is fast, and the sound is still very soft after the start. Not only the start is good, the four types of PAO car is better than before, the original 5000 miles to change the oil, now it can run 15000 kilometers, and the power decline period has also been extended to 10000 kilometers, the decline is slow, the back running power is still strong, it is really the best oil I have ever used.

If you are looking for cold start-up performance, it is recommended to choose an oil with better fluidity at low temperatures.

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.

Hello. Personally, I still recommend Mobil oil. Good.

It is advisable to use a fully synthetic motor oil because it lubricates well and can extend the life of the engine.

Fully synthetic motor oil.

Fully synthetic motor oil is the highest grade of motor oil. It is ethylene and propylene dispersed from gas or natural gas in **, and then refined into a lubricating liquid composed of macromolecules through complex chemical reactions such as polymerization and catalysis. In essence, it uses the best ingredients, chemical reaction and artificial control to achieve the expected molecular form, the fully synthetic oil molecules are arranged neatly, the ability to resist foreign variables is naturally very strong, so the physique is better, thermal stability, antioxidant reaction, and the ability to resist viscosity changes are naturally much stronger than mineral oil and semi-synthetic oil, so it is also the highest.

The car has been driving for 6 months, no more than one year, you must go to do maintenance and change the oil, now there are many varieties of engine oil on the market, many car owners do not know how to choose, so what kind of oil is better for car maintenance?

What kind of engine oil to change for the car should be chosen according to the type of car, for example, if it is a naturally aspirated engine, then as long as it is guaranteed to be a regular brand of engine oil, the viscosity is suitable. If it is a turbocharged engine car, in addition to taking into account the regular product and viscosity, there are also very strict requirements for the high and low grades of engine oil.

Many car owners will judge the viscosity according to the viscosity of the label when choosing the oil, and they think that the larger the mark, the higher the viscosity, but in fact, the viscosity of the engine oil will decrease with the rise of temperature, only by choosing the right oil viscosity, it will not affect the normal play of the engine, so the specific choice of what kind of oil should be decided according to the type of engine and driving mode.

Maintenance of car oil:

1. The maintenance of automobile oil is changed according to the mileage, and the quality of the engine oil can also be checked. When the oil has been used for half a year, check once a month or before leaving the car, take out some oil from the oil dipstick to see the oil level and the quality of the oil, feel okay and continue to use, and replace it immediately if the quality is poor, so that the degree of damage to the car will be reduced;

2. Every 5,000 kilometers driven, it is recommended to do a "small maintenance" for the car. The oil filter and oil are changed during "minor maintenance". To do maintenance, you should choose a regular 4S shop, although it is a little more expensive, but the quality is ***.

When doing major maintenance, the "three filters" should be replaced, that is, fuel filter, air filter, oil filter and oil;

3. After the vehicle is driven for a long time, a lot of impurities will accumulate in the oil filter and gasoline filter, resulting in insufficient gasoline combustion, reducing fuel efficiency and increasing fuel consumption, so it is better to replace it regularly. The air filter will also accumulate dust and bacteria, if not replaced, such air circulation in the car, will affect human health. According to the condition of the car, the maintenance personnel will also propose to replace the spark plug (roughly driving more than 30,000 kilometers), brake fluid (roughly driving more than 40,000 kilometers) and so on.

Ask him. This depends on your own use, if you often use your car, and the loss is relatively large, you must often go to maintenance, about two or three months to maintain it, routine maintenance items: oil and oil filter replacement is mainly for the maintenance of the lubrication system.

The main function of the lubrication system is to effectively lubricate the various parts of the automobile engine to prevent excessive wear. The function of the oil filter is to remove all kinds of impurities in the oil to ensure the normal lubrication system, the oil filter should be replaced with the oil when changing the oil, and the car needs to be maintained every 5000km under normal circumstances.

Ask him. The general mineral oil can be changed every 5,000 kilometers, the synthetic oil can be extended to 7,500 kilometers, and the fully synthetic oil can be changed about 10,000 kilometers. In terms of time, a car that has driven less than 5,000 kilometers for half a year should also consider changing the engine oil after half a year.

Familiar with the label of engine oil, all car owners can sit in the right number, no longer have to face various brands of engine oil confused, but in actual use, we also have various misunderstandings.

When you buy a new car, there is an ironclad discipline, every 5000 you have to change the oil, why change it? Because the original engine oil has deteriorated and does not provide normal lubrication and cleaning effect, it has to be replaced! But everyone ignores one point, he is a reference for semi-synthetic engine oil, in fact, the lubricity of mineral engine oil begins to decline after 3000 kilometers, so everyone will hear two different engine sounds after changing the oil, and the new engine oil obviously has a slippery sound!

Because of the different lubrication levels of engine oil, good engine oil often leads to better engine performance and better fuel economy, using fully synthetic engine oil can save an average of 1 liter or more of gasoline per 100 kilometers compared to mineral engine oil. And with two different grades of oil, there will be a huge difference in the performance of the engine after 100,000 kilometers! It's not a matter of a few dozen dollars left!

There is no fixed cycle for the oil replacement cycle, which is related to many factors such as the car environment, habits, oil types, etc., without considering the influence of factors such as environment and habits, if you want to change the cycle for a long time, you can use fully synthetic engine oil.

Normally, mineral oil needs to be replaced for about 5000 km, semi-synthetic oil about 8000 km, and fully synthetic oil about 10000 km. It is important to note that motor oil also has a shelf life, and it is generally not recommended to change the cycle for more than 18 months. So you can't run thousands of kilometers a year, and you don't necessarily have to use synthetic motor oil.

He doesn't increase the power, because no matter what the oil, it only cools and lubricates, and it can't change the engine power.

1. Common sense of oil replacement.

How often should the oil be changed? How much oil do I need to change at a time? Regarding the replacement cycle and dosage of engine oil, everyone is particularly concerned about the issue, the most direct is to check their own car maintenance manual, which is generally very clearly introduced.

But there are also many people's maintenance manuals that have long been missing, so you need to know more about it. Generally speaking, the oil replacement cycle is 5000 kilometers, and the specific replacement cycle and dosage should be judged according to the relevant information of the model.

Not all models are suitable for car owners to change the oil by themselves, but we can learn to look at the oil scale to determine if it is time to change the oil. Also, the oil filter must be changed at the same time as the oil is changed.

Second, the use of antifreeze common sense.

Antifreeze is best used all year round, in addition to the function of antifreeze cooling, antifreeze also has the effect of cleaning, rust removal and anti-corrosion, reducing the corrosion of the water tank and protecting the engine. Pay attention to the color of antifreeze and do not mix it.

3. Common sense of brake fluid use.

The function of the brake system is closely related to the brake fluid, and when checking to replace the hardware such as brake pads, brake discs, etc., don't forget to see if the brake fluid needs to be added and replaced.

Fourth, transmission oil.

In order to ensure that the car steers flexibly, it is necessary to check the transmission oil frequently, whether it is gear oil or automatic transmission oil, you must pay attention to the type of oil, which is usually high.

Maintenance items. What are the daily car maintenance items? The car is a very complex large machine, and the mechanical parts will inevitably wear and tear during operation, coupled with the influence of external man-made, environmental and other factors, resulting in the wear and tear of the car.

According to the driving condition of the car, the manufacturer will formulate the corresponding car maintenance items, what are the common maintenance items?

Project. 1. Small maintenance.

The contents of the minor maintenance:

Minor maintenance generally refers to the routine maintenance items done at the time or mileage specified by the manufacturer to ensure the performance of the vehicle after the car has traveled a certain distance. This mainly includes changing the oil and the oil filter.

Intervals for small maintenance:

The duration of minor maintenance depends on the oil used and the effective time or mileage of the oil filter. The expiration date of mineral engine oil, semi-synthetic engine oil and fully synthetic machine-based bulk oil is also different for different brand grades, please refer to the manufacturer's recommendation. The oil filter element is generally divided into two types: conventional and long-lasting, and the conventional oil filter element is replaced with the oil, and the long-term oil filter element lasts longer.

Supplies during minor maintenance:

1. Engine oil is the lubricating oil for engine operation. It can lubricate, clean, cool, seal, reduce wear and other functions of the engine. It is of great significance to reduce the wear and tear of engine parts and extend the service life.

2. The oil filter machine is a component of Boying's filter oil. Engine oil contains a certain amount of gum, impurities, moisture and additives; In the process of engine work, the metal chips generated by the friction of various parts, the impurities in the inhaled air, and the oil oxides are all the objects of the oil filter element. If the oil is not filtered and goes directly into the oil circuit, it will have a detrimental effect on the performance and life of the engine.

Hello, the quality of the original engine oil can also be, but there is still a certain gap compared with the market models of big brands

It's not that the higher the oil, the better its maintenance. You need to look at the oil number on your vehicle, and the chain is wide and loose according to the label on him to use, so that it is the most appropriate, don't blindly think that the best socks are really good.

No matter what brand of engine oil, there are a lot of English and numbers on the oil drum, as long as you know the rules, you can understand the numbers on it. Engine oil classifies engine lubricants according to viscosity and quality, and SAE and API are widely used internationally.

The SAE grade represents the viscosity grade of the opening. SAE30 and SAE40 are single-grade oils, and SAE10W-30 and SAE15W-40 are multi-grade oils. Among them, the higher the number in front of w, the lower the low temperature viscosity of the oil, the better the protection ability of the car when it starts cold.

The number after w is an indicator of the high temperature resistance of engine lubricants.

According to SAE, there are 6 types of oils used in winter, 4 types in summer, and 16 types in winter and summer. There are 0w, 5w, 10w, etc., and the smaller the number in front of w, the lower the applicable temperature. The higher the number, the higher the applicable temperature.

There are 5w w 30 and so on for general oil, and the difference between the numbers before and after w is large, the larger the applicable temperature range. In most parts of our country, you can use general engine oil in both winter and summer.

According to the API classification, the openings of the S series and C series are not arranged in alphabetical order, but are divided into several levels. For example, the designation SAE 10WSD indicates a winter lubricant with a viscosity classification of SAE 10W and a quality level of API SD. Gasoline engine lubricants are divided into five grades: EQB to EQF, and EQB grade oil can be used for general household cars.

According to the use of their own vehicles to choose engine oil, most of the vehicles in the urban area, and the local temperature is not much different, the vehicle is not an imported high-end car, comprehensive consideration with 5w 30 mineral oil. Mineral oil is relatively inexpensive, and can be used for lubrication, cooling, rust prevention, and sealing for general vehicles.

If it is a high-end car, it is recommended to choose synthetic engine lubricating oil, synthetic oil has a higher viscosity index than general mineral oil, and the viscosity change with temperature change is small, so it can still protect the engine in high temperature and severe cold conditions, and it is not easy to produce sludge and carbon deposits. However, the maintenance cost is higher.

Some 4S stores provide original special engine oil for brand vehicles, and the quality of the oil is definitely no problem, which is suitable for your vehicle, but it is not the best engine oil. If you take care of your vehicle, you can appropriately choose the same brand of vehicle engine oil.
