How often do I go to the oil change center to change the oil
The car is now an important means of transportation for people. With the improvement of the economy, more and more people buy a car. Many people buy a car, but they don't understand the internal structure of the car and how to maintain it. Many people know that the maintenance of the car is very important. Good maintenance can keep the car in good condition at any time, and also make your car use longer. There is a big difference between car maintenance and ordinary electric vehicle maintenance, and the maintenance methods of each part are very different
as we all know, the two major factors that affect the quality of engine oil are the way I usually take and the quality of engine oil. So I basically don't take the bumpy road. If I use the best quality engine oil, I don't need to replace it? It's not like that. There is a change cycle for the engine oil. Although there is no mandatory standard, we can still find the relevant maintenance manual of our own model for reference. When we usually go to the 4S shop for maintenance, they will use the engine oil with the relevant label and quality specified by the manufacturer and replace it according to the maintenance manual. At ordinary times, car owners should pay attention to the replacement of fully synthetic oil after 8000-10000 km, semi synthetic oil after 5000-8000 km and mineral oil after 5000 km. Vehicles that have not been used for a long time can be replaced once every half a year or so
there will be a recommended maintenance period on the Three Guarantees certificate attached to the purchase of the car. Engine oil, that is, engine lubricating oil, can play the role of lubrication and wear rection, auxiliary cooling and cooling, sealing and leakage prevention, anti rust and anti-corrosion, shock absorption and buffering
changing the engine oil on time can not only prolong the life of the engine, but also effectively rece the fuel consumption of the car itself.
to use the original engine oil, you need to change it according to the maintenance manual
after you buy a new car, the front is maintained in the 4S shop, and the oil used for maintenance is also the so-called original engine oil. In this case, you just need to follow the cycle in the car maintenance manual to change the oil
for example, most Japanese cars are changed every 5000 km or half a year, while most European and American cars are changed every 7500 km or half a year. However, it is suggested that the first maintenance should be carried out in advance, because the engine is in the first running in period before the first maintenance, and more mechanical debris will appear in the engine. It's absolutely beneficial for the engine to do maintenance earlier and let them out
Generally speaking, the replacement cycle of mineral oil is half a year or 5000 km, semi synthetic oil is half a year or 7500 km, and full synthetic oil is half a year or 10000 kmit is also necessary to shorten the replacement cycle under unconventional driving conditions
however, both the guidelines in the maintenance manual and the suggestions of self purchased oil refer to the replacement cycle under the condition of "normal driving". And "general driving" refers to driving often on the highway, rarely stop and walk
for example, in urban driving, traffic lights and traffic jams cause cars to idle or stop for a long time, often driving within a short distance of less than 8km, driving to work, but the car is not hot at work. These belong to the unusual "attrition driving". This kind of "attrition driving" will lead to a large amount of carbon deposition in the engine, which will affect the life of the engine
for this kind of "lossy driving", we suggest that the oil change mileage should be reced by 20-30%. By shortening the action of replacing mileage, the carbon deposit in the engine can be cleaned to ensure the normal operation of the engine. How much is the rection? For example: ordinary minerals are not replaced at 3500-4000 km in advance, and semi synthetic oil is replaced at 5500-6000 km in advance; The fully synthetic engine oil is replaced at 7500-8000 km ahead of time
in harsh environment, the replacement cycle should be appropriately shortened
in addition to "wearing driving" which will affect the oil replacement cycle, the harsh driving environment will also affect the oil replacement cycle. For example, when driving on the road with st and gravel, the influx of a large amount of sand and st will aggravate the blockage of the oil filter and the impurity content of the oil. In this case, it is difficult to guarantee the validity of the engine oil on the original basis, so it needs to be replaced in advance
another example is driving across climate zones e to long-distance driving, or driving in areas with temperature lower than - 20 ℃; The rapid change of climate and low temperature will cause the deterioration of engine oil, thus greatly shortening the "life" of engine oil. Like the above two cases, we also recommend that the oil change mileage be reced by 20-30%
accurately judge whether the oil needs to be changed
1. Observe through the oil test paper
take out a small amount of oil from the oil ruler and drop it on the oil test paper, and then keep it still for one night, waiting for the above oil to completely diffuse on the test paper. If the edge between the oil ring, precipitation ring and diffusion ring of the diffused oil is harder, the performance degradation of the oil will be more severe
2. According to the driving feeling after changing the engine oil, the performance of the engine oil has a "shelf life". In a certain period, when you feel that the power is "fleshy" and the acceleration is slow, it means that the "shelf life" of the engine oil is up and you need to change the engine oil
in addition, when you change the engine oil, you feel that the power is obviously improved, That means the mileage of the last oil change was a little too long. Next time, you can advance 500 km appropriately, so that you can find a more accurate mileage of oil change 1-2 times
last but not least, it's better to change the oil filter as well as the oil. The function of the oil filter is to intercept the impurities in the oil. If it is not replaced in time, the accumulated impurities will cause blockage. Light will cause insufficient oil pressure, poor lubrication of mechanical parts, serious will cause excessive wear of the engine
there are three kinds of general engine oils: fully synthetic, semi synthetic and mineral engine oils
generally, the synthetic engine oil should be changed every 10000 km or once a year
generally, semi synthetic engine oil should be replaced every 7500 km or 7-8 months
generally, mineral oil should be changed every 5000 km or 6 months
if the engine oil is not changed for a long time, the oil will deteriorate and the lubricating effect will be reced. When the engine is working, the internal parts can not be lubricated, which will lead to the wear of the internal parts of the engine and shorten the service life of the engine.
of course, one way is to check the oil. It should not be a big problem to maintain the oil once a year. The key is the quality and grade of the oil you use. If the quality is good and the grade is high, the oil change time can be prolonged. If you use ordinary oil, you should always check the quality of the oil. If the oil is not well lubricated, it will damage the vehicle. When the engine oil is used for half a year, check it once a month or before driving. Take some oil from the dipstick to check the oil level and quality. Feel good to continue to use, poor quality immediately to replace, so the degree of damage to the car will be reced< There are four ways to identify the engine oil:
1. Smell the engine oil. Draw out the oil dipstick and smell it near your nose. If there is a strong sour smell, it means that the engine oil has deteriorated and should be replaced
2. Hand twisting method: grind the old engine oil repeatedly with thumb and index finger. The good hand feeling is lubricity, less wear debris and no friction. If you feel impurities, poor viscosity, or even astringent, you should replace it
3. Color discrimination method: take a clean white filter paper (a better tissue paper can be used) and drop some old engine oil on the paper. After the standby oil leaks, the good quality engine oil is dry and smooth without powder, and the Yellow soakage band is clear. It is dark brown with impurities and should be replaced
4. Light method: take out the oil dipstick and hold it 45 degrees high. Observe the oil drops under the light, and you can clearly see that there is no wear debris in the oil drops. If there is too much debris, it should be replaced.
when the engine works in this extremely harsh environment, the engine oil can lubricate, cool down and clean the stolen goods proced by the engine friction, so as to ensure the normal operation of the engine and prolong the service life of the engine. So the oil is very important for the normal operation of the engine and prolonging the service life
however, engine oil does not have the function of self purification like blood. Over a long period of time, the engine oil will be mixed with various wastes and need to be released, so it needs to be replaced with new engine oil
many people tell us to change the engine oil once every 5000 km or once every half a year, which of the two indicators should be pressed first
for example, when we arrive at 5000 km, even if we only drive for two months, we have to do maintenance
if it's half a year, even if it's only 3000 km, you still have to do the maintenance
sometimes we hear from the old drivers around us that the time and kilometers are higher than these two. Because the maintenance time set by the manufacturer often takes into account various complex climates, different driving habits and complicated road conditions, the one they set is relatively conservative
some of our friends will have a kind of entanglement. They want to make full use of the engine oil as far as possible. If they change the engine oil early, they feel that it will be wasted. I changed it late, and I'm afraid it's bad for the engine. I can only say that you are really a qualified economic man. It's very suitable to marry you
if the 4S store gives a relatively conservative oil change time, some people will think, "do they want to make money for me?" and so on
for newly bought cars, the first maintenance can be carried out ahead of time, because the engine is in the first running in period before the first maintenance. The first pot of oil is full of metal debris, which does great harm to the sealing devices. Especially for the model with turbine, the sealing damage to the turbine shaft is greater. It is absolutely beneficial for the engine to "let them out" by early maintenance
let's talk about it in turn. How did they determine the 5000 km and how did the algorithm calculate it
before explaining the 5000 km, please forget the number of 5000 km
the maintenance of our engine is calculated according to the actual operation time or safe operation life
that is to say, when oil is added to the engine, there is a certain operating time limit. As long as our car is on fire and the engine is running, oil will enter the engine and start to work. Even if our car does not drive forward and does not generate kilometers, the engine is also calculating the running time
the engine oils we add are divided into three types: mineral oil, semi synthetic oil and fully synthetic oil, which guarantee different engine running time
like our ordinary mineral oil, its operation time is 100 hours under normal circumstances, while the fully synthetic oil is of better quality, and its operation time is twice that of mineral oil, which is 200 hours
let's calculate it according to the average speed. If we are driving in the city, the average speed is 30 km / h. If we multiply it by 100 hours, it will be 3000 km. If we multiply 30 km / h by 200 hours, it will be 6000 km
of course, if the road condition is better and the average speed can reach 60 km / h, the engine oil can reach 6000 km to 12000 km at that time. Therefore, the impact of road conditions on oil change is still great
for example, in our "first traffic jam" Beijing, when there are many traffic lights and traffic jams, the car idles or stops for a long time, often drives within a short distance of less than 10km, drives to work, but the car is not hot when it arrives at the unit. It's possible that your car will have to change the oil after driving 1000 km
in some cities, there are too many bad weather such as sandstorm and haze, which will also rece the driving range of our cars. The unclean air will enter the engine and burn together with the oil. If the combustion is not sufficient, the waste generated will increase, and the cleaning burden of engine oil will increase
these belong to the unusual "attrition driving". This kind of "attrition driving" will lead to a large amount of carbon deposition in the engine, which will affect the life of the engine
in this case, in order to ensure the longer service life of our engine, I suggest that you shorten the oil change mileage by 20% - 30%. This is based on the maintenance manual and the oil purchased. By shortening the action of replacing mileage, the carbon deposit in the engine can be cleaned to ensure the normal operation of the engine.
general engine oils are divided into three types, fully synthetic, semi synthetic and mineral engine oils
generally, the synthetic engine oil should be changed every 10000 km or once a year
generally, semi synthetic engine oil should be replaced every 7500 km or 7-8 months
generally, mineral oil is changed every 5000 km or 6 months.
