How to determine the time to change the oil, I have driven a car for 12 years, changed 4 cars until now, I have summarized my maintenance experience in the past 12 years, summarized the losses I have suffered, and I also know how to determine the time to change the oil. It's not by cycle or by time, the 5000 kilometers that the 4S shop said is actually fooling you to waste money, if you are still struggling with when the engine oil needs to be replaced, what kind of oil is better for our car, then this article will definitely help you, it is my own experience in exchange for losses.
First of all, I want to use my friend's personal experience to explain a problem to you, that is, if your car is maintained in a 4S shop, and the maintenance cost is only more than 200 per time, then I suggest that you must not change the oil beyond the time said by the 4S shop. People tell you to change 5,000 kilometers or ask you to change it in 6 months, you have to go on time, otherwise, your engine will definitely get worse and worse, and it may even have to be overhauled in the later stage.
I've been writing for so long, and I've never shared with you this experience of my friend, his car is always maintained in the 4S shop, but he doesn't always change the oil according to the 5000 km cycle that the 4S shop said. Because he was a novice at the time, the old driver around him told him that the 4S shop cheated money, and deceived you to waste money, in fact, there was no need to run 5,000 kilometers to change the oil, you just drove seven or eight thousand kilometers and then changed, it doesn't matter. So he listened to the old driver's words, and drove to seven or eight thousand kilometers every time before going back for maintenance. Although the cost of maintenance is very low, his car has poor power after a few years of driving, and it is easy to stall at the beginning (manual transmission).
This is a real case that happened to me, I have never taken it out to talk about it, his problem is very clear, that is, I went to the 4S shop to change the poor quality engine oil, and I took it upon myself to extend the maintenance cycle. More than 200 maintenance once and has included the cost of man-hours, then you can imagine, 4S shop 120 yuan of man-hours should always be wanted, right? The man-hours cost took more than 120 yuan, the oil filter of the two together is only worth more than 100 yuan, then everyone use their brains to think about the more than 100 yuan he can give you what kind of engine oil? You can know without using your brain, they are also the most common and worst mineral engine oil for you, the protection effect of this oil on the engine is relatively poor.
And this kind of oil lamp has a lot of impurities, and it is basically to its limit at 5000 kilometers, and you may still use the car in the urban area. At this time, you didn't change it, but you extended it to six or seven thousand kilometers to change, and the various indicators of the engine oil have dropped, and you are still using it, which causes it to produce a lot of sludge inside the engine. These sludge will cause the running resistance inside the engine to become larger, so when he uses the car in the later stage, there will be a series of problems such as knocking, weak power, and high fuel consumption. If he continues to use it like this, if he continues to use it like this, there will be no accident, and his car will definitely have problems in 10 years.
So I told you at the beginning, if you are changing the oil in the 4S shop, and you only pay more than 200 yuan for each maintenance, then the 4S shop calls you 5000 kilometers to change, you must change 5000 kilometers, you are asked to change in 6 months, you must also change in 6 months, otherwise the engine must not be maintained in place. In fact, whether your car is 350,000 yuan or 100,000 yuan, I recommend that you use fully synthetic engine oil. Because the fully synthetic engine oil has a better protection effect on the engine, the life is longer, and the engine is protected to a certain extent and the number of maintenance can be reduced.
Fully synthetic engine oil is also divided into low grades, it is slightly cheaper than 300 on the line, cheap cars use this, the expensive SP level 0W-20 of this model of engine oil is only 600 less, you can also use this if you are not bad for money. If you use SP grade fully synthetic engine oil, then you can only maintain it once a year when you drive 10,000 kilometers or even 12,130,000 kilometers, because this kind of engine oil is really of good quality, and the maintenance of the engine is relatively in place, extending one or two thousand kilometers, according to my own experience in using the car for 12 years, it is completely no problem.
This kind of fully synthetic engine oil is not easy to produce sludge impurities in the engine, and in the process of lubricating the engine, it can also clean the iron powder worn down inside the engine, and clean off the mess, it has the function of cleaning the engine, and the quality of the oil film formed is relatively good and not easy to break, and the protection effect of the engine is better. If your car has been using fully synthetic engine oil since the new car leaves the factory, then after 10 or 8 years of driving, you will find that your car has better power and lower fuel consumption.
How do we determine the maintenance interval of a fully synthetic engine oil like this? You don't need to look at the so-called 6 months or a year to determine your maintenance interval according to the mileage you actually drive. Synthetic engine oil is generally changed once every 10,000 kilometers, but we must pay attention to one point, it is generally changed once every 10,000 kilometers. If you drive without traffic jams, then you can actually extend it by one or two thousand kilometers. Like I said above, you can change it for 12,000 or 13,000. But if you often use traffic jams in urban areas, then you must change 10,000 kilometers on time, and even you have to change 9,000 kilometers. Another point to remind everyone is that if you drive less than 5,000 kilometers a year, you also have to change the oil once a year or once a year and a half.
In general, the cycle of changing the engine oil is not fixed, the good quality oil can be properly adjusted according to the actual situation of our car, the 10,000 kilometers given above the oil is just a reference, you can advance a little in advance, you can extend a little bit. But if the oil you use is too bad, you must change it regularly according to the cycle, I hope my explanation can help everyone.
