Recently, the news about the increase and emulsification of engine oil in the 2.5L displacement model of Asian Dragon has been widely circulated on the Internet, and there is even suspicion of artificial amplification behind the news.
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 together with the technical department of the parent company.
At the same time, Toyota China also stressed that 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, which is not a quality problem.
Back to Asia Dragon, at present, the increase of engine oil and emulsifying phenomenon are extremely isolated phenomena, which will not have any impact on engine performance, let alone product quality problems. However, we appeal to 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 the latest TNGA architecture of Toyota. Thanks to the latESt TNGA architecture, technical and modeling advantages, and the platform with luxury brand lexus es, the sales volume of Asian Dragon has risen rapidly and steadily after its listing under the impetus of precise marketing. In just one year, the sales volume has surpassed the competitors who have cultivated the market for many years. In the past January, the sales volume of Asian Dragon in the terminal market exceeded 12,. At present, the momentum of selling Asian dragons continues to rise.
maybe a tree attracts the wind. The news of "increasing and emulsifying engine oil" once again pushed the 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 still responded positively and actively for the first time, reflecting Toyota's social responsibility and responsibility.
Is the increase and emulsification of engine oil in FAW Toyota Asian Dragon a rare case or a common phenomenon? What causes the increase and emulsification of engine oil in vehicles? Does it harm the engine of vehicles after the increase and emulsification of engine oil?
for ordinary car users, because they don't know the car technology, the news of "increased oil and emulsification" is really worrying. To this end, Spicy Car Company randomly found a Chengdu Asian Dragon owner, Mr. Zhang, from the fans of the owner, and specially invited Mr. Mao Jianjun, a senior technical expert who has been engaged in maintenance for 17 years in the automobile industry and won the gold medal in the global automobile after-sales competition.
under the witness of real car owners, technical experts and the media, we opened the engine oil cover of this Asian Dragon 2.5L model, which has traveled for more than 1, 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 Toyota Corolla. In September last year, he changed cars and bought Toyota's new flagship car, Asian Dragon. Recently, it was reported on the Internet that the engine of Asia Dragon had increased engine oil and emulsifying phenomenon. However, since the car was picked up, it has traveled more than 1, kilometers, and the driving experience is very good, and there has not been any abnormal situation.
"I think that emulsifying phenomenon of engine oil is very likely an individual phenomenon. Since we have the opportunity to monitor vehicles with the media and authoritative experts, is the engine oil emulsified? I believe that after opening the engine oil cover, everything will be revealed 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 several cars such as Honda and Toyota, but a normal state that all cars will have 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 very worried about the increase in engine oil, so they can go to the 4S shop for inspection.
"oil emulsification" existed a long time ago. 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 need not care, because the slight phenomenon will not affect the lubrication performance of the engine at all, nor will it hurt the vehicle engine, or even break down.
with the help of Mao Jianjun, a senior auto maintenance expert, the oil cover of Mr. Zhang's Asian Dragon engine was opened. After careful inspection by Mao Jianjun, it was found that there was no residual foamy liquid of any color on the engine oil cover. Therefore, there was no oil emulsifying phenomenon on Mr. Zhang's car. At the same time, Mao Jianjun pulled out the oil dipstick for inspection, and found that the liquid level did not exceed 25mm of the F line, and the phenomenon of increased oil did not happen. After careful examination, Mr. Zhang's inner concerns were completely dispelled. "I believe in Toyota's technology and product quality."
According to Mao Jianjun, the main reason for oil emulsification is that the engine cannot be fully warmed up repeatedly (the water temperature is at? 8? Below) state (low speed and short distance, temperature? 1? Degree? /3? Minutes), a small amount of condensation water in the engine can't evaporate and is mixed into the engine oil, so emulsifying phenomenon will occur at the inner side of the oil filler cap and other parts. At the same time, the occurrence of engine oil emulsifying phenomenon has a certain relationship with the car habits of car owners, such as long-term parking of vehicles and so on.
Mao Jianjun also introduced that there are many reasons for the increase of engine oil. First, the engine factory will inject engine oil according to the F scale line, but there will be certain tolerance. When the oil is actually injected, it exceeds the F line. If it does not exceed the F line by 25mm, it is still within the specified range. Second, when replacing the oil in vehicle maintenance, it may also exceed the F line of the oil level. Third, the increase of engine oil is related to the environment and habits of car use. Under the condition 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. Fourth, when measuring the oil level, the oil level will be different due to the inclination of the ground and the engine temperature (the higher the oil temperature, the greater the oil expansion rate).
However, from the inspection of a randomly selected Asian Dragon, it is true that the increase and emulsification of engine oil in Asian Dragon is not a common phenomenon, but an example. At the same time, Mao Jianjun, an after-sales service technical expert, has also popularized some common knowledge about the increase and emulsification of engine oil, which is a normal phenomenon in most cases. Even when the water evaporates, the emulsification will naturally disappear, or it will naturally disappear after running for a long distance. So, please don't panic for all Asian dragon owners.
if you are the owner of the Asian dragon, and you are still uneasy after seeing the news of the increase and emulsification of engine oil, you can also go to the local FAW Toyota 4S shop for vehicle inspection. I believe that the service of Toyota, a world-renowned automobile brand, will definitely satisfy you and be responsible to the owner.
How to solve and avoid oil emulsification
1. Find the original oil 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 good quality engine oil
Under normal circumstances, sometimes the engine oil will have a slight emulsifying phenomenon. For the slight phenomenon, high-quality all-synthetic engine oil can effectively prevent and solve it. For example, Topland lubricating oil has high anti-emulsification performance, which can well solve the normal engine oil emulsifying phenomenon even in a long-term humid environment.
3. Pay more attention in winter
Oil emulsification is also affected by temperature, and the probability of oil emulsifying phenomenon is greater at low temperature during the winter solstice, so we should pay more attention to engine oil emulsifying phenomenon in winter.
4. Increase the warm-up time
Short-distance driving or low-temperature environment will make the water not be discharged in time, which may cause emulsification. Therefore, the owner can increase the warm-up time and drive at a high speed to make the oil temperature rise quickly and discharge the water in time.
correct method for measuring engine oil
1. When confirming the amount of engine oil, factors such as ground flatness and engine oil temperature (the higher the temperature, the greater the expansion rate of engine oil) will affect the measurement, so it is crucial to adopt the correct measurement method:
2. Ensure that the vehicle stops on a smooth road to improve the accuracy of oil level detection.
3. Turn off the engine, etc? 5-1? Minutes or so, let the engine cool down, and let the oil that stays 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 dipstick hole again, wait for a few seconds to take it out, and observe the position of oil stains on the oil dipstick.
