No matter whether the news is accurate or not, Toyota China attaches great importance to it and immediately checks the source links such as procurement, design, production and after-sales with the technical department of the parent company.
At the same time, Toyota China also stressed that at present, it has not received any feedback from consumers about vehicle failures caused by increased engine oil and emulsification. Judging from the current situation, the oil level of all models is within the standard range, not a quality problem.
Speaking of Asian dragons, at present, the increase of engine oil and emulsifying phenomenon are extremely rare phenomena, which will not have any impact on the engine performance, and there will be no product quality problems. However, we appeal to the Asian dragon owners who have doubts to go to the local 4S shop for testing in time to dispel their psychological worries and concerns.
Asia Dragon is a brand-new B+ class car product of FAW Toyota, which is based on Toyota's latest TNGA architecture. Thanks to the latest TNGA architecture, technology and modeling advantages, as well as the platform with luxury brand lexus es, the sales volume of Asia Dragon has increased rapidly and steadily after listing, driven by precision marketing. In just one year, the sales volume has surpassed that of competitors who have been deeply involved in the market for many years. In the past 65438+ 10 month, the sales volume of Asian dragons in the terminal market exceeded10.2 million. At present, the momentum of selling Asian dragons continues to rise.
Maybe a tree can catch the wind. The news of "increasing emulsified engine oil" once again pushed Asian Dragon to the focus of public opinion. However, from the current point of view, although this phenomenon will not bring substantial danger to vehicles, as a world-renowned automobile brand, Toyota responded positively for the first time, reflecting Toyota's social responsibility and responsibility.
Is it an individual case or a common phenomenon that FAW-Toyota Asia Dragon Engine Oil increases emulsification? What causes the increase and emulsification of vehicle oil? Is it harmful to the vehicle engine after the oil is emulsified?
For ordinary car users, because they don't understand car technology, the news of "increased oil and emulsification" is really worrying. To this end, the spicy car company randomly found a Chengdu Asian dragon owner, Mr. Zhang, from the owner fans. At the same time, we specially invited Mr. Mao Jianjun, a senior technical expert engaged in 17 maintenance in the automobile industry and a gold medal winner in the global automobile after-sales competition.
Under the witness of real car owners, technical experts and the media, we opened the oil cover of this Asian Dragon 2.5L model, which has traveled more than 10,000 kilometers, hoping to objectively and truly interpret the increase of oil in Asia and emulsifying phenomenon through this presentation.
According to Mr. Zhang, the owner of Asian Dragon, he has always liked Toyota's products. The first car was a Toyota Corolla. Last September, he changed cars and bought Toyota's new flagship car, the Asian Dragon. Recently, it was reported on the Internet that the engine of Asian Dragon had increased engine oil and emulsifying phenomenon. However, since the car was picked up, it has traveled more than 10,000 kilometers, and the driving experience is very good. There has been no abnormality.
"I think oil emulsifying phenomenon is probably an individual phenomenon. Since there is an opportunity to monitor vehicles with the media and authoritative experts, is the oil emulsified? I believe that after opening the oil cover, everything will come out and my concerns will be dispelled. "
According to Mao Jianjun, a senior automobile maintenance expert, the increase of engine oil is not a "patent" of Honda, Toyota and other cars, but a normal state that all cars will appear under certain working conditions and using conditions. Measure the oil level according to the standard measurement method, if the liquid level does not exceed the F line? 25mm, but users are still worried about the increase of engine oil, so they can go to the 4S shop for inspection.
Oil emulsification has existed for a long time. In the automobile market, almost all automobile brands and models may have the phenomenon of "oil emulsification", which is not entirely a product quality problem, but an "acceptable" normal situation. Don't make a fuss about it. If the emulsifying phenomenon is not serious, the owner should not care, because the slight phenomenon will not affect the lubrication performance of the engine at all, nor will it harm the vehicle engine, or even cause a failure.
With the help of senior auto maintenance experts, the oil cover of Mr. Zhang's Asian Dragon engine was opened. After careful inspection, Mao Jianjun found that there was no residual foamy liquid of any color on the oil cover. Therefore, there is no engine oil emulsifying phenomenon in Mr. Zhang's car. At the same time, Mao Jianjun pulled out the dipstick for inspection, and found that the liquid level did not exceed 25mm of the F line, and there was no increase in oil quantity. After careful inspection, Mr. Zhang's inner concerns were completely dispelled. "I believe in the technology and product quality of Toyota."
According to Mao Jianjun, the main reason for oil emulsification is that the engine cannot be fully and repeatedly warmed up. 80? Below) state (low speed and short distance, temperature? 10? Degree? /30? Minutes), a small amount of condensed water in the engine can't be evaporated and mixed into the engine oil, so emulsifying phenomenon will occur at the inside of the fuel filler cap and other parts. At the same time, the occurrence of engine oil emulsifying phenomenon is also related to the car habits of car owners, such as long-term parking of vehicles and so on.
Mao Jianjun also said that there are many reasons for the increase in engine oil. First, the engine factory will inject engine oil based on the F scale line, but there will be some tolerance. The actual injection of oil exceeded the F line. If it does not exceed 25mm from the F line, it is still within the specified range. Second, when changing the oil for vehicle maintenance, it may also exceed the F line of the oil level. Third, the increase in engine oil is related to the environment and habits of car use. In the case of low temperature in winter, if the engine is not fully warmed up, some unburned gasoline vapor will dissolve into the engine oil, which is a normal physical phenomenon existing in all engines. Fourthly, when measuring the oil level, the oil level will be different due to the different inclination of the ground and engine temperature (the higher the oil temperature, the greater the expansion rate of oil).
However, from the inspection of a randomly selected Asian dragon, it is true that the increase in emulsification of Asian dragon oil is not a common phenomenon, but a case. At the same time, Mao Jianjun, an after-sales service technical expert, also popularized some common sense about the increase and emulsification of engine oil. In most cases, it is a normal phenomenon, even when the water evaporates, emulsification will disappear naturally, or it will disappear naturally after running for a certain distance. So, please don't panic for all Asian dragon owners.
If you are the owner of Asian Dragon, you are still uneasy after seeing the news that the oil price has increased and emulsified. You can also go to the local FAW Toyota 4S shop to check the car. I believe that the service of Toyota, a world-famous automobile brand, will satisfy you and be responsible for the owner.
How to solve and avoid oil emulsification
1, find the original text in time?
If oil emulsifying phenomenon is found, repair it in time, find the root cause, avoid the problem from getting worse, and replace the oil if necessary.
2. Use high-quality engine oil
In general, sometimes the oil will have a slight emulsifying phenomenon. For minor phenomena, high-quality synthetic engine oil itself can effectively prevent and solve them. For example, Toplang lubricating oil has high anti-emulsification performance, which can solve the problem of normal engine oil emulsifying phenomenon even in a long-term humid environment.
3. Pay more attention in winter
The emulsification of engine oil is also affected by temperature. When the temperature is low in winter, the probability of engine oil emulsifying phenomenon is high, so we should pay great attention to engine oil emulsifying phenomenon in winter.
4, increase the hot car time
Short-distance driving or low-temperature environment will prevent water from being discharged in time, which is easy to cause emulsification. Therefore, the owner can increase the warm-up time and drive at high speed, so that the oil temperature can rise rapidly and drain water in time.
Correct method of engine oil measurement
1. When confirming the oil quantity, factors such as ground flatness and oil temperature (the higher the temperature, the greater the oil expansion rate) will affect the measurement, so it is very important to adopt the correct measurement method:
2. Ensure that the vehicle stops on a smooth road surface and improve the accuracy of oil level detection.
3. Turn off the engine, etc. 5- 10? Let the engine cool down for about minutes, and let the oil staying at the upper part of the engine fully flow into the oil pan.
4. Take out the oil dipstick and wipe it, then insert it into the hole of the oil dipstick again, wait for a few seconds to take it out, and observe the position of oil stains on the oil dipstick.
