Why do you want to change the oil in the prescribed time?
What will happen if you don't change the oil?
Many of our friends have heard a lot about how long they need to change their oil. They say 5000 kilometers, 10000 kilometers, three months and half a year. We go to 4S shop, ask around friends, and check the Internet, the statement is not the same, who listen to the end?
In fact, if we can not fully understand the oil, it will easily become a pony crossing the river, and lose judgement and don't know which is right.
Today, let's talk about the oil change.
Oil is relative to the car, just as blood is the same as the human body, and the engine is the heart of the car. In engine operation, piston motion will cause friction. Gasoline will deflagrate in the cylinder, and the temperature in the engine will reach 600 degrees. Meanwhile, it will also produce metal particles and other wastes.
The engine works in this extremely harsh environment. Oil plays the role of lubricating, cooling, cleaning the stolen goods generated by engine friction, ensuring the normal operation of the engine and prolonging the life of the engine. So oil is very important for the function of the engine to operate normally and to prolong the life of the engine.
But the oil is not like the blood has self purification, the time is long, the oil will be mixed with all kinds of waste, it needs to be put out, so the new oil will be replaced.
Many people tell us 5000 kilometers to change one or half a year to change the oil, these two indicators, which first to the first which.
For example, we are 5000 kilometers here, even if we have only been open for two months, we also need to do maintenance.
If half a year, even if only 3000 kilometers, or to do maintenance.
Sometimes we have heard from the side of the old drivers in time and the number of kilometers, will be higher than the two. Because the time required for maintenance is often taken into account in all kinds of complex climate, driving habits and complex road conditions, so they are relatively conservative.
Some of our friends will have a kind of entanglement to use the oil as much as possible, change early, and feel waste. It was late and was afraid of bad engine. I can only say, you are really a qualified man of economic application, and marry you are more suitable for life.
If the 4S shop, oil change time are relatively conservative, some people will think, "they are not to earn my money" etc..
However, here we propose three flavor, buy a new car for the first time, maintenance can advance, because the engine in the first insurance before, in the first period, this article a pot of oil which is full of metal debris, great damage to the sealing device, especially with turbine models, more of the turbine shaft seal damage earlier, do maintenance them put out, there is absolutely no harm to the engine.
Then let's say, how do they fix this 5000 kilometers, and how the algorithm is calculated.
Before explaining this 5000 kilometers, please forget the 5000 kilometre number first.
The maintenance of our engine is calculated according to the actual operating time or the safe operation life.
That is to say, the oil is added to the engine, and there is a certain limit of running time. As long as our car is on fire and the engine is running, there will be oil entering the engine to start working. Even if we don't drive ahead, we will not generate kilometers, and the engine is also running time.
The engine oil is divided into three categories: mineral oil, semi synthetic oil and full synthetic oil. The three types of engine oil guarantee the operation time of the engine is different.
Like our ordinary mineral oil, in general, its running time is 100 hours, while the total synthetic oil is of better quality and running time is twice as much as mineral oil, which is 200 hours.
We calculate according to the average speed. If we drive in the city, the average speed is 30 kilometers per hour, and then multiplied by 100 hours, that is 3000 kilometers, and 30 kilometers per hour multiplied by 200 hours, it means 6000 kilometers.
Of course, if the road is better, the average speed can reach 60 km / h, and the oil will go up to 6000 to 12000 kilometers. Therefore, the influence of road conditions on oil change is still very great.
If in our first block Beijing, traffic lights and traffic jams are very large, cars will run idle or stop for a long time, often driving within a short distance of less than 10km, driving to work, but not yet hot to unit cars. It is possible that your car is going to change the oil for 1000 kilometers.
Sand, some of these city haze weather is not particularly good more, will reduce our car mileage, not clean air into the engine oil and mixed combustion, incomplete combustion, produce waste oil, clean the burden will increase.
These are non - General "consuming driving". This "consumable driving" can lead to a large amount of carbon deposition in the engine, which affects the life of the engine.
In this case, in order to protect our engine for a longer life, I suggest you shorten the mileage of the engine oil by 20%-30%, which is based on the maintenance manual and the proposal of the purchased oil itself. By shortening the action of changing the mileage, the carbon deposition in the engine is cleaned to ensure the normal operation of the engine.
How much is it? I'll give you some data for reference.
Ordinary minerals do not change to 3500-4000 kilometers in advance.
The semi synthetic oil is changed to 5500-6000 km in advance.
