Chapter 026: Strange Questions

The customer turned around and left angrily, but let him introduce the situation, indicating that Zhao Hong's car purchase was stable.

Fang Yuan nodded and smiled at Zhao Hong, standing in the customer's position and pondering carefully, he could understand Zhao Hong's hesitation just now, after all, the interior was indeed a bit miserable, but Zhao Hong's budget was also a bit low, only 100,000 Huaxia coins, Fang Yuan had done his best to satisfy the customer.

In fact, Liu Liang had already introduced the configuration of this BMW 5 Series to the customer just now, but Zhao Hong didn't pay attention to it.

Since the customer wants to introduce himself again, Fang Yuan took the trouble to say: "This BMW 5 Series is the 2010 520Li luxury type, with a mileage of 133,000 kilometers, licensed in September 2010, a four-door five-seat sedan, the new car price of the year was 459,800 yuan, and the on-site car dealership was listed for 99,600 yuan, and the personal first-hand car, including the transfer, and the customer went to the insurance ......"

"The vehicle is 4981 mm long, 1846 mm wide, 1477 mm high, wheelbase 3028 mm, standard C-class car, equipped with a 2.0L 152 horsepower L4 engine, front and rear drive, with 6-speed manual automatic AT transmission, maximum power 112, maximum torque 200, maximum speed 217, 000 acceleration in 10.6 seconds......"

"After all, it is a 2010 car, compared to the current BMW, the configuration is not high, only tire pressure monitoring function, seat belt is not fastened reminder, ABS anti-lock, body stability, electric sunroof and other basic configurations, now popular cruise control, steep hill descent, hill assist, automatic tailgate, automatic parking, engine start and stop, etc., none of them. ”

"Hey. The configuration is low, Zhao Hong just sighed, he also knows that his car purchase budget is small, and it is unrealistic to ask too much.

"What is rare is that the front and rear are independent suspension, and the ride is very comfortable. In view of the fact that Zhao Hong is a car novice, Fang Yuan deliberately told him that this BMW 5 series main engine factory requires the addition of No. 95 gasoline, and don't be greedy for cheap No. 92.

"Well, well, it's not going to be added randomly. Zhao Hong nodded again and again, saying that he would definitely do it according to the manufacturer's requirements.

Zhao Hong didn't understand the car, how Fang Yuan asked him, how he did it, and didn't feel that there was any difference between adding 95 or adding 92 gasoline.

Liu Liang, who had been listening honestly all the time standing next to him, couldn't help it, and asked curiously: "The main engine factory requires 95 gasoline, but you can't add 92, what if I add it wrong?" Is there any harm?"

"95 and 92 refer to the different labels of gasoline, mainly the different octane number. Fang Yuan patiently explained that the anti-riot energy of the two, that is, the stability of the two is different, the higher the mark, the more stable it is, and the less likely it is to explode.

As for what Liu Liang said, the main engine factory requires the addition of No. 95 gasoline, and the addition of No. 92 gasoline, what is the harm, it is necessary to analyze the specific problems in detail, and see how the operating instructions of the main engine factory are written.

Some OEMs' manuals indicate that it is required to add 92 gasoline and above, and it is recommended to add 95.

It means that adding 92 gasoline is the minimum standard, and it is best for car owners to add 95.

In this case, the main engine factory itself has taken into account the low-grade oil consumption, and it doesn't matter if the owner wants to add 92 or 95, as long as it does not exceed the minimum range.

The instructions of some OEMs clearly state that only 95 and above gasoline can be added, and 92 can not be added.

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

At this time, if the owner wants to save money, or is negligent for a while, or the eldest sister of the gas station makes a mistake, the 95th gasoline is replaced by 92nd gasoline, and it will be troublesome.

This is because when the octane number of gasoline used in the engine is lower than the octane number required by the main engine factory, it may cause a shock explosion and damage the engine.

This leads to the deterioration of engine thermal efficiency, power efficiency, fuel economy, exhaust emissions, etc., as well as the increase in fuel consumption and fuel consumption.

Seeing the worry on Zhao Hong and Liu Liang's faces, Fang Yuan smiled slightly, and told them that the engine was not so fragile, and if they added it wrong once or twice, it was actually not too much of a problem.

Because today's engines are generally equipped with knock sensors, the ECU will actively adjust and can use low-octane gasoline by delaying ignition.

At this time, the engine can operate normally with low-grade gasoline that does not meet the standard, but when driving the vehicle, attention must be paid to avoid high-load conditions such as large throttle, sharp acceleration, and full-speed driving.

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

"In general, if you ask to add 95 models, when you encounter the wrong gasoline or only have a low grade, it will not be too much of a problem to add it once in a while, and it is okay to be emergency. Fang Yuan warned the two, but for a long time to add low-grade gasoline that does not meet the requirements of the main engine factory, the engine will face relatively harsh working conditions for a long time, and the life of valves, tongue plugs, cylinder blocks and other components will be seriously shortened, and the money saved will outweigh the losses compared with the cost of car repair.

Fang Yuan finally warned the two of them that the situation of No. 95 gasoline just now, if it is a luxury car with more than one million, you have to add No. 98 gasoline, and if you accidentally add No. 92 gasoline, you must pay extra attention to the condition of the car.

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

"Oh, I see. Zhao Hong and Liu Liang nodded at the same time, they understood that they should refuel according to the standard, and it costs a lot of money to overhaul the engine, not to mention that there is an accident on the road.

Liu Liang understood that he couldn't add low-grade gasoline, and he suddenly had a novel idea: "If I ask for No. 92 gasoline, how about I keep adding No. 95 gasoline?"

Fang Yuan smiled, there is indeed a situation where the owner has been adding high-grade gasoline, but whether it is useful or not must be analyzed on a case-by-case basis.

"At this time, it is necessary to divide old cars and new cars. Fang Yuan told Zhao Hong and Liu Liang that old cars with a long age generally have a lot of carbon deposits in the cylinder.

Too much carbon deposition will lead to frequent knocking, which will affect the normal operation of the engine, cause power drops 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 not necessary for new cars, and it is not helpful to do anything, and it is a waste of money.

"If I ask for 92 gasoline, can I mix 92 and 95?" Zhao Hong was also interested, and asked a more bizarre question like a curious baby.

"Mixed up?"

Your brain circuits are very strange.

The problems of customers who understand cars are tricky, and the problems of customers who don't understand cars are wonderful, Fang Yuan has learned this kind of nonsensical ideas countless times, and he has been entertained by Zhao Hong, who doesn't understand anything.

But try to explain it and try not to mix it up.

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

Gasoline manufacturers are different, the process is different, and it is not simply believed that half a tank of No. 98 and half a tank of No. 92 can be exchanged for a half tank of No. 95.

So half box No. 95 and half box No. 92, what the hell can be redeemed, no one is sure, it's no problem to do it once in a while, and if you do it often, you will die by yourself.

If the mark deviates too much and the knocking is too severe, it will cause the body to shake abnormally, and the engine noise will suddenly become louder, so you need to stop immediately, find a trailer and wait for rescue.

"I see. Zhao Hong and Liu Liang let out a sigh in unison, and suddenly realized.

At the same time, Zhao Hong feels that Fangyuan's business knowledge is very proficient, he is very patient with customers, and he is even more 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." ”

"Good, good. Fang Yuan also took out his mobile phone happily, and the two of them scanned the code to add friends.

Seeing that Fang Yuan was so familiar with the customer, Liu Liang's eyes were red to death, and he also wanted to add a WeChat with the customer, exchange a mobile phone number or something, but the customers didn't pay attention to him.

"If there is anything I don't understand in the future, I will trouble you more. Zhao Hong gently patted Fang Yuan's shoulder, and smiled and asked Fang Yuan to give advice.

"It should be, it should be. Fang Yuan treats customers honestly, saying that if there is a problem, contact at any time, and must know everything and say everything.

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

Finally served the customer uncle comfortably and made up his mind to buy a car, Liu Liang was excited and his liver was beating wildly, and the more he looked at Fang Yuan, the more he looked like the God of Wealth.

"Wait. Fang Yuan stretched out his hand very calmly to stop Zhao Hong, "I also have to tell Brother Zhao some precautions." ”

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

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

Because BMW models can only design the engine in this way in order to get excellent handling, and when it reaches a certain number of years and mileage, there will be symptoms of burning engine oil.

In addition, the rubber valve cover of the engine deteriorates rapidly over time, and loses its elastic life, resulting in oil leakage failure.

......

Zhao Hong quietly listened to Fang Yuan's explanation, but there was no trace of impatience, and there was no regret not to buy this BMW 5 Series.

Because of Fang Yuan's professionalism and kindness, he had already conquered Zhao Hong, and he believed that Fang Yuan was for his own good, so that he would not make mistakes in the future use process.

"Don't say anything, brother, I'll buy a car in your store, a hundred rest assured, ten thousand rest assured. Zhao Hongyi was so excited that he even spoke his hometown, and finally shouted, "Let's go and pay the money and sign the contract." ”

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

"Huh?" Zhao Hong and Liu Liang exclaimed at the same time, especially Zhao Hong looked at Fang Yuan very puzzled, his eyes were confused.

Liu Liang lowered his head very ashamedly, he knew that Fang Yuan did this to return the customer to himself, and he didn't want to covet a little credit.

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

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

"I ...... Big...... Elder brother. The short three words made Liu Liang's heart warm, and when he accompanied the customer to the manager's office, he reluctantly looked back at Fang Yuan, and his eyes were a little red.
