How many kilometers to replace Dr. Ying s lubricating oil

I haven't heard of this brand of oil! It should be produced in a small factory.

Automobile lubricants are used very frequently during maintenance, and high-quality lubricants can not only protect the engine

In addition to reducing the number of oil changes, it also saves on gasoline costs.

At the same time, be careful not to be caused.

Improper use of lubricating oil causes car failure, improper use of "improper method of use" generally originates from.

Four "misconceptions" about lubricants by car owners.

Misconception 1: Lubricating oil is often added without changing.

It is correct to check the lubricating oil frequently, but only replenishing and not replacing it can only make up for the lack of oil quantity, but cannot fully compensate for the loss of lubricating oil performance.

During the use of lubricating oil, the quality will gradually decline due to pollution, oxidation and other reasons, and there will also be some consumption, so that the quantity will be reduced.

Myth 2: Additives are useful.

A truly high-quality lubricant is a finished product with a variety of engine protection functions, a formula that already contains a variety of additives, including anti-wear agents, and the most important thing about the balance of the lubricant is to ensure that the performance is fully realized.

Adding other additives by yourself not only does not bring additional protection to the vehicle, but is easy to react with the chemicals in the oil, resulting in a decrease in the overall performance of the oil.

Myth 3: When the lubricating oil turns black, it's time to change the oil.

This understanding is not comprehensive.

For lubricating oil without static dispersant, the color blackening is indeed a sign that the oil has been seriously deteriorated, but the lubricating oil used in modern automobiles is generally added with a quiet decomposer.

This sedative washes off the adhesive film and black carbon deposits that adhere to the piston and disperses them in the oil to reduce the formation of high-temperature precipitation in the engine, so the color of the lubricating oil is easy to turn black after a period of use, but the oil is not completely deteriorated at this time.

Misconception 4: Add more lubricating oil if you can.

The amount of lubricating oil should be controlled between the upper and lower scale marks of the dipstick.

Because too much lubricating oil will come from the gap between the cylinder and the piston.

It enters the combustion chamber and burns to form carbon deposits.

These deposits can increase the compression ratio of the engine and increase the tendency to detonation;

The red-hot state of carbon deposits in the cylinder is also easy to cause premature ignition, such as falling into the cylinder will aggravate the wear of the cylinder and piston, and will also accelerate the pollution of lubricating oil.

Secondly, too much lubricating oil increases the stirring resistance of the crankshaft connecting rod, which increases fuel consumption.

Now as long as it is the oil produced by the official manufacturer, there is no problem, different car oil models are different, Japanese cars are basically 20 or 30 oil, German 40, now basically 5w-30 or -40 can be 10w.

This is a kind of MLM model of promotion, the quality is not good, tell you that the oil is good, are powerful and profitable, don't believe this kind of publicity, imported big brands have not been studied, a small place in Bayan, Heilongjiang has been made, if it is so good, you don't need to promote, you will take the initiative to find it! Don't be fooled anymore....

Some time ago, my friend's car was changed for free, but the power of the car was obviously insufficient, and there was a pungent smell, and it was not 3000 kilometers to take the dipstick, there is really no free lunch in the world, it is driven by interests, and now there is no one who can believe it.

My friend asked me to change it, I didn't dare to go, and I don't know if it's good or bad, it's free.

The quality is OK, hundreds of cars in our unit are using this, I also visited their factory, quite powerful, rest assured that there is no problem.

Semi-synthetic 7000 is no problem, mineral oil is best 5000 fully synthetic 12000 is no problem.

1.Replace according to the manufacturer's recommended oil change interval. Car manufacturers or lubricant manufacturers will give recommended oil change intervals, which is commonly referred to as 5000 km oil change intervals.

The domestic oil change cycle is usually about 5000-15000 kilometers, of course, there are many lubricating oil propaganda 50,000 kilometers, 100,000 kilometers a change, and even 5,000 kilometers without oil "record", it is undeniable that the oil change cycle is being extended with the improvement of technology. In addition to the manufacturer's recommendation, the recommendation of the mechanic of the auto repair shop is also an important reference.

2.According to the index of lubricating oil and oil products, it is judged whether to replace it. Lubricating oil has its own indicators, the national standard (GB T 8028-2010) also stipulates the oil change index of lubricating oil in the process of use according to the change of oil index, and the owner and mechanic can also replace it according to these indicators.

The oil change index is mainly judged from the changes in viscosity, pH value, moisture, flash point, metal elements, etc., and when the lubricating oil reaches a certain index, it should be replaced in time.

In order to save trouble and money, some terminal stores are sloppy when putting lubricating oil, resulting in the old lubricating oil polluting the new lubricating oil, which not only affects the effect of the lubricating oil, but also may lead to the rapid deterioration of the new lubricating oil, and eventually damage the engine. The correct way to put the lubricating oil is to put it clean at high temperature, then fill it with special cleaning oil for cleaning, then start the engine to idle for 10-15 minutes, then put it clean, and finally add new lubricating oil.

In short, the lubricating oil should be replaced in time, neither too little can be added, which is easy to cause the burning of the parts, nor too much, which is easy to enter the combustion chamber and cause the burning of oil.

Dr. Kunlun often shares the knowledge of car maintenance, how to judge whether the oil change interval is appropriate:1The performance of engine oil has a "shelf life", in a certain period of time when you feel that the power is "very meaty" and the acceleration is slow, it means that the "shelf life" of the engine oil has arrived, and you have to change the oil.

2.When you change the oil and feel a noticeable increase in power, it means that the mileage of the last oil change is a bit too long. Next time, you can properly advance 500 kilometers, so that you can find a more accurate mileage for changing the oil in 1-2 times.

The most direct way to detect whether the oil needs to be replaced is to observe, we need to use the oil test strip to park the car on the flat road, use the oil dipstick to dip a little oil, drop it on the oil test strip, according to the description of the test strip, after a period of time and then observe, and compare with the legend to determine whether the oil needs to be replaced, note that if only the lubricating oil is not replaced, it can only make up for the lack of lubricating oil, but can not make up for the loss of lubricating oil performance. During the use of lubricating oil, the quality will gradually decline due to pollution, oxidation and other reasons, and there will be some consumption, so that the quantity will be reduced, so the oil can be changed regularly.

Lubricating oil is burned, evaporated, sheared and cracked during use, and it produces useless residual carbon and ash powder, which are mixed into sludge with metal particles dropped by system wear. When the system has too much sludge and the viscosity of the oil drops to the lower limit of use, it should be replaced. Be careful

Fully synthetic engine oil is generally replaced once every 1 year or 1w km. It depends on the driving conditions of the vehicle, if the driving road is very congested, it is recommended to replace it 1000 kilometers or 1 month in advance, because the vehicle will also lose the engine oil life when idling.

There are four types of vehicles that recommend the use of fully synthetic motor oil.

1.For turbocharged models, it is recommended to use fully synthetic motor oil.

2.For large displacement models, it is recommended to use fully synthetic engine oil.

3.For internal direct injection engines, it is recommended to use fully synthetic engine oil.

4.For cars that are often driven in extreme climates, it is recommended to use fully synthetic motor oil.

Fully synthetic engine oil is maintained for 10,000 kilometers or once a year.

Synthetic motor oil is a motor oil synthesized by human chemical methods, and according to the purpose of use, synthetic motor oil can change various compositions. Work on the development of synthetic motor oil began in the 30s. At that time, due to the harsh conditions of aircraft engine oil, which required a higher performance engine oil, some chemical factories began to develop and produce synthetic engine oil.

Synthetic motor oil is a kind of artificially manufactured motor oil, in the production process, a variety of natural substances are selected for chemical decomposition, and then synthesized with various other substances, and finally synthetic motor oil is produced.

Synthetic motor oil is the product of modern chemical technological advancements. The advantages of synthesizers are numerous. For example, synthetic engine oil has higher lubricity than mineral engine oil, less frictional resistance, less oxidation, and strong cleanliness.

Fully synthetic engine oil is maintained for 10,000 kilometers or once a year.

Fully synthetic engine oil can be used for the next maintenance after the vehicle travels 7,500 kilometers, if the climate is good, the air is clean or something, and the oil quality is good, it will be 10,000 kilometers for full synthetic stability, or much better.

If the number of kilometers is small, it is still maintained at 5000-7500 kilometers.

How often should I use a fully synthetic motor oil?

7,000 kilometers is good for maintenance, and Japanese cars are longer than 10,000 kilometers.

Around 7500. The good full synthesis can go to 8000 to 9500, or even 10000 to change it.

It is recommended to change the steering oil every 40,000-50,000 km or 2-3 years. The explanation is as follows:

There are also more standardized enterprises will refer to the car maintenance requirements of large foreign automobile companies, and make more reasonable provisions in combination with the current road conditions, air quality and technical level of users.

In order to prevent the steering oil from being too dirty or deteriorating and causing other consequences, it is recommended to change the steering oil every 40,000-50,000 kilometers or 2-3 years.

Engine oil: 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. It is known as the "blood" of automobiles.

Engine oil is made up 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.

As a kind of machinery, the engine has its common requirements for lubricating oil compared with general machinery, such as appropriate viscosity, certain performance requirements such as anti-oxidation, anti-wear, anti-corrosion and viscosity temperature.

The gear oil is changed every 40,000 kilometers and the clutch three-piece set is changed, the power steering oil is changed every 100,000 kilometers, and the brake fluid is changed in two years!

Hope it helps.

3 to 50,000 kilometers are changed every two years.

For general motorcycles, the first oil change for a new car during the run-in period is generally 500 1000 kilometers, and then the oil can be changed every 2000 kilometers. The brand of oil is not very important when changing the engine oil, as long as it is guaranteed to be ** not counterfeit or inferior engine oil, ** about the same ** engine oil, its oil quality is also similar. According to the kilometer distance, changing the engine oil is the biggest mistake, and the best oil change is generally the most suitable for changing the season!

You can change it 4 times a year, and you don't need to calculate how many kilometers! When changing seasons, you can change the engine oil of different grades according to different temperatures, so that the engine can have a better working condition! Clean the air cleaner frequently, and the standard amount of oil!

There are two kinds of motorcycles: one is a two-stroke motorcycle, one is a four-stroke motorcycle, and now basically the two-stroke motorcycle has basically been discontinued, and they are all four-stroke motorcycles. The new car needs to change the engine oil at 300 kilometers (the new car oil is provided by the seller), the second time when the motorcycle runs 600 kilometers, the third time when the oil is changed at 1000 kilometers, this is the first three times, maintenance is very important.

After the first three maintenances, maintenance is carried out every 500 km. This will make your motorcycle last longer.

How often to change the motorcycle oil:

1) The viscosity of the engine oil changes greatly at high temperature, and it is generally believed that when the deviation of the 100 kinematic viscosity value exceeds 20%, it must be replaced;

2) The cleaning and dispersion performance of the engine oil is reduced, and the carbon deposits generated by the work process of the dispersed engine cannot be dissolved;

3) The engine oil is acidic, containing a large amount of acidic oxides, which is easy to corrode the parts;

4) The oil contains metal particles, which aggravates the wear of the parts during operation (the filtration effect of the filter structure is not thorough);

5) The flash point of the oil is reduced, which affects the safety. This is because frequent cold starts can cause gasoline to enter the crankcase through the collar clearance. The national standard stipulates that the flash point value of gasoline engine oil shall not be less than 210.

Take the straddle 125 men's street car as an example, the oil change during the run-in period of the new car is changed by the number displayed on the head of the meter, and the oil is changed every 1500-2000 kilometers in the future. If it is a high-grade SL or above fully synthetic lubricating oil (more than 90 yuan per L retail **), the service life is about 5000 kilometers. During the break-in period, the engine and gearbox need to be cleaned with lubricating oil, so the oil needs to be changed frequently, so it is not necessary to use fully synthetic engine oil to avoid waste.

If it is a scooter, the service life of the lubricating oil should be shortened accordingly, such as the replacement period of SG grade mineral oil is within 1000 km, and the fully synthetic engine oil is 3000 km, it doesn't matter if it exceeds a little, but it is longer than that, because the speed of the scooter is high, the temperature is also high, the oil loses its lubrication, and the engine wear increases, resulting in increased engine resistance and vibration, and fuel consumption also increases accordingly.
