Chapter 026: Strange Problem
The customer turned around and left angrily, but asked to introduce the situation, indicating that Zhao Hong's car purchase was stable.

Fang Yuan nodded slightly at Zhao Hong and smiled, thinking carefully from the customer's standpoint, he could understand Zhao Hong's hesitation just now, after all, the interior was indeed a bit horrible, but Zhao Hong's budget was also a bit low, only [-] Huaxia coins, Fang Yuan has tried his best to satisfy customers.

In fact, Liu Liang had already introduced the configuration of this BMW [-] Series to the customer just now, but Zhao Hong didn't pay attention to it.

Since the customer wanted to introduce himself again, Fang Yuan took the trouble to say: "This BMW 5 Series is a 2010 520Li luxury model with a mileage of 13.3 kilometers. It was licensed in September 2010. It is a four-door and five-seater sedan. It was a new car that year. The tax-included price is 09 yuan, the on-site car dealership is 45.98 yuan, the personal first-hand car, the transfer is included, and the customer buys the insurance by himself..."

"The vehicle is 4981mm long, 1846mm wide, 1477mm high, and has a wheelbase of 3028mm. It is a standard C-class car equipped with a 2.0L 152 horsepower L4 engine, front rear drive, and a 6-speed automatic manual AT transmission. The maximum power is 112, the maximum torque is 200, the maximum speed is 217, and the acceleration from zero to 10.6 takes [-] seconds..."

"After all, it is a 2010 car. Compared with the current BMW, the configuration is not high. There are only tire pressure monitoring functions, seat belt reminders, ABS anti-lock braking, body stability, electric sunroof and other basic configurations. Now popular Cruise control, steep slope descent, uphill assistance, automatic rear door, automatic parking, engine start and stop, etc., none of them."

"Hey." With low configuration, Zhao Hong just sighed. He also knew that his car purchase budget was small, and it was unrealistic to ask too much.

"What's rare is that the front and rear are independent suspensions, and the ride is very comfortable." Since Zhao Hong is a car novice, Fang Yuan deliberately told him that this BMW 95-series OEM requires 92 gasoline, so don't be greedy for cheap Add number [-].

"Well, well, I won't add it randomly." Zhao Hong nodded again and again, expressing that he must follow the manufacturer's requirements.

Zhao Hong didn't understand cars, how did Fang Yuan ask him, and how did he do it, he didn't think there was any difference between adding 95 or 92 gasoline.

Liu Liang, who was standing by and listening honestly, couldn't help it, and asked curiously: "The main engine factory requires 95 gasoline, and 92 cannot be added. What if I make a mistake? Is there any harm? ?”

"95 and 92 refer to the different grades of gasoline, mainly because of the different octane ratings." Fang Yuan patiently explained that the anti-violence performance of the two, that is, the stability is different, the higher the grade, the more stable, the less stable. Easy to explode.

As for what Liu Liang said, the main engine factory requires the addition of No. 95 gasoline, and added No. 92 gasoline. What harm is there? You need to analyze specific issues and see how the OEM's instruction manual is written.

Some OEM manuals indicate that: No. 92 gasoline and above are required, and No. 95 is recommended.

It means that gasoline with No. 92 is the minimum standard, and it is best for car owners to add No. 95.

In this case, the OEM itself has taken into account the low-grade fuel consumption, so it doesn’t matter if the car owner wants to add 92 or 95, as long as it does not exceed the minimum range.

Some OEM manuals clearly state that only 95 and above gasoline can be added, and 92 gasoline cannot be added.

Fang Yuan pointed out emphatically that some models of BMW, Audi, Volvo, etc. clearly require that 92 gasoline cannot be used.

At this time, if the car owner wants to save money, or is negligent for a while, or the lady at the gas station makes a mistake, it will be troublesome to add 95 gasoline to 92 gasoline.

Because the octane number of gasoline used by the engine is lower than the octane number required by the OEM, it may cause knocking and damage the engine.

It leads to the deterioration of the engine's thermal efficiency, power performance, fuel economy, exhaust emissions, etc., as well as increased fuel consumption and more fuel consumption.

Seeing the worried faces of Zhao Hong and Liu Liang, Fang Yuan smiled slightly, and told them that the engine is not that fragile, and if it was added wrongly once or twice, there is actually no big problem.

Because the current engine is generally equipped with a knock sensor, the ECU will actively adjust it to apply low-octane gasoline by delaying the ignition.

At this time, low-grade gasoline that does not meet the standard is added, and the engine can operate normally. However, when driving the vehicle, care must be taken to avoid high-load conditions such as large accelerator, rapid acceleration, and full speed driving.

Otherwise, the cylinder pressure and temperature will become high, and knocking will easily occur.

"Generally speaking, for models that require the addition of No. 95 gasoline, if there is a wrong addition or only low-grade gasoline, it will not be a big problem to add it once in a while. It is okay for emergencies." Fang Yuan warned the two, but the long-term Low-grade gasoline that does not meet the requirements of the OEM, the engine will face relatively harsh working conditions for a long time, and the life of valves, pistons, cylinders and other components will be severely shortened, and the money saved is not worth the cost of repairing the car.

Finally, Fang Yuan warned the two of them that the 95 gasoline was just mentioned. If it is a luxury car over a million dollars, it needs to be filled with 98 gasoline. If you accidentally add 92 gasoline, you must pay special attention to the condition of the car.

If there is a knocking situation, don't go any further, you must stop and wait for rescue, otherwise the engine will be damaged and you will be in big trouble.

"Oh, that's how it is." Zhao Hong and Liu Liang nodded at the same time, and they understood that they should refuel according to the standard, not to mention that it would cost a lot of money to overhaul the engine, and there was an accident on the road, which was even more regrettable.

Liu Liang understood that low-grade gasoline cannot be added, and he suddenly had a novel idea: "If you are required to add 92-grade gasoline, how about I keep adding 95-grade gasoline?"

Fang Yuan laughed. It is true that there are situations where car owners keep adding higher grades of gasoline, but whether it is useful or not depends on the specific situation.

"At this time, we need to distinguish between old cars and new cars." Fang Yuan told Zhao Hong and Liu Liang that old cars with a long history generally have a lot of carbon deposits in their cylinders.

Too much carbon deposit will lead to frequent knocking, affecting the normal operation of the engine, causing power drop and loss of power.

At this time, changing to high-grade gasoline can alleviate knocking, restore power, and reduce fuel consumption.

It is useful to add high-grade gasoline to old cars, but it is unnecessary for new cars. It will not provide any help, and it is a waste of money.

"If it is required to add 92 gasoline, can I mix 92 and 95?" Zhao Hong also became interested, and asked a more bizarre question like a curious baby.

"Mix it together?"

Your brain circuit is very clear.

Customers who know cars have tricky questions, and customers who don't know cars have weird questions. Fang Yuan has experienced this nonsensical idea countless times, and Zhao Hong, who doesn't understand anything, is amused by it.

But still try to explain, try not to use it indiscriminately.

The additives in gasoline are very complex, and they play different roles in different situations.

Gasoline manufacturers are different, and the process is different. It cannot be simply assumed that a half box of No. 98 and a half box of No. 92 can be mixed into a half box of No. 95.

Therefore, no one can be sure what kind of ghosts can be exchanged for a half box of No. 95 and a half box of No. 92. It is okay once in a while, but if you do it often, you will kill yourself.

If the label deviates too much and the knocking is too serious, it will cause the body to vibrate abnormally, and the engine noise will suddenly become louder. At this time, it is necessary to stop immediately and find a tow truck to wait for rescue.

"I understand." Zhao Hong and Liu Liang said in unison, suddenly realizing.

At the same time, Zhao Hong feels that Fang Yuan is very proficient in business knowledge, is very patient with customers, and is kind and sincere.

He took out his mobile phone with a smile, clicked on WeChat, and said to Fang Yuan: "Brother, let's add WeChat, brother, I want to make you a friend."

"Okay, okay." Fang Yuan also readily took out his mobile phone, and the two scanned the QR code to add friends.

Seeing that Fang Yuan was so close to the client, Liu Liang was so jealous that he wanted to add a WeChat account with the client, exchange cell phone numbers, etc., but the client ignored him.

"If there is anything I don't understand in the future, I will bother you more." Zhao Hong patted Fang Yuan's shoulder lightly, and asked Fang Yuan to teach him with a smile.

"It should be, it should be." Fang Yuan treated the customer sincerely, saying that he would contact him at any time if he had any questions, and he would know everything without saying anything.

"Okay, I'm very satisfied with this car, so I'll pay for it and pick it up." Zhao Hong is now completely convinced of Fang Yuan's professionalism, and believes that the model he introduced must be the most suitable for him, and he can't wait to buy the car.

Finally, Shu Tan, the uncle of the client, made up his mind to buy a car. Liu Liang was so excited that his little heart thumped wildly. The more he looked at Fang Yuan, the more he looked like the God of Wealth.

"Wait." Fang Yuan reached out his hand to stop Zhao Hong very calmly, "I still want to tell Brother Zhao some precautions."

"Oh? Precautions?" Zhao Hong stared at Fang Yuan curiously, waiting for him to continue.

"BMW's common problems are engine oil burning, oil leakage, gearbox oil leakage, etc. This BMW 520Li has the same problem. Brother Zhao, you should pay special attention and check it frequently." Fang Yuan explained that these problems are inherent in BMW cars The common problem is almost unavoidable.

Because BMW models can only design the engine in this way in order to obtain excellent control, after a certain age and mileage, symptoms of burning oil will appear.

Moreover, the rubber valve cover of the engine will rapidly age and change over time, losing its elasticity and causing oil leakage.

……

Zhao Hong listened quietly to Fang Yuan's explanation, but he didn't show a trace of impatience, and he didn't regret not buying this BMW [-] series.

Because of Fang Yuan's professionalism and kindness, he has already conquered Zhao Hong. He believes that Fang Yuan is doing it for his own good, and for his own use so that he will not make mistakes in the future.

"Don't say anything, brother, I'll buy a car in your shop, don't worry about one hundred, ten thousand." Zhao Hong was so excited that he even spoke his hometown dialect, and finally shouted loudly, "Come on, let's go to the car shop." Money, sign the contract."

The customer happily decided to buy a car, but Fang Yuan took a step back and made Liu Liang face Zhao Hong: "Brother Liu, take Brother Zhao to the office to go through the formalities."

"Ah?" Zhao Hong and Liu Liang exclaimed at the same time, especially Zhao Hong looked at Fang Yuan very puzzled, with confusion in his eyes.

Liu Liang lowered his head in shame. He knew that Fang Yuan had returned the client to him by doing this, and he didn't want to take any credit.

"Brother Zhao, it's like this. Liu Liang is my eldest brother." Fang Yuan explained to the client, "It was his turn to receive you just now, and I was only here to help, so you are his client, so Brother Liu should take you to sign the contract." contract."

"That's it." Zhao Hong finally remembered that it was Liu Liang who received him at the beginning.

"I...Brother...Brother." The three short words warmed Liu Liang's heart. When he accompanied the client to the manager's office, he reluctantly turned his head to look at Fang Yuan, and his eyes were a little red.
