Ideals are one thing, and execution is another.

The next day was the new trading day. Lin Yi personally installed an oil-refining artifact for the owner who won the lottery.

However, it is not just about installing oil-refining artifacts, but the banners made overnight read the words "Installing oil-refining artifacts and checking the condition of the car for free."

Lin Yi also conducted a physical examination for every installed car.

Most car owners these days have certain maintenance capabilities.

However, most of this ability is not from a professional background, and it is almost all a wild way passed down by word of mouth.

For example, the replacement of engine oil is not to change the oil, but to drive the car to a relatively high place, unscrew the oil drain screws at the oil pan, and use a small basin to follow the oil filled with impurities.

Wait until the oil in the small basin is clear, then pour the "clean" part back.

Not to mention whether the "cleanness" of the naked eye is really clean. During this process, the engine oil will be oxidized and deteriorated for a lot of time in contact with the air, which will make it unable to achieve the lubrication effect it should be.

Fortunately, the engines in this era are strong and resistant, and even so, they will only wear excessively, and it is not impossible to start.

Lin Yi checked several cars and knew their problems.

"My car is in very good condition! I keep it on time every time!" An old man patted his chest and pointed at the Jetta with his panda color scheme.

Lin Yi looked at the same Jetta as the South African version, with a white body and a black bumper, pulled out the dipstick, glanced at it and said, "Your car is not being maintained by yourself."

"I don't have time to take care of it! I always go to a special store to maintain it!"

"Then there is something wrong with your car." Lin Yi wiped the dipstick with a clean towel.

"I...what can I have in this car?" The old man was anxious.

"The oil in your car is added with sugar."

"This...how is this possible!"

"Does the car shop you maintained urge you to change the oil every time? The oil you replaced will be specially shown to you to see how dirty it is?"

Lin Yi took a piece of toilet paper, inserted the dipstick into the engine and pulled it out, allowing the oil to drip.

On the white toilet paper, the oil stained open, leaving some flocculent residue.

He pointed to the impurities and said, "These are white sugar."

"This...this..." The brother was stunned.

The car owners around him cheered, "We have seen that the maintenance of the shops outside is unreliable, look!"

Lin Yi did not agree with these people's words, and he asked again, "Have you changed your gearbox oil?"

"I have changed the transmission oil, but I have changed it. No... Is there a problem!" The old man was in despair.

"If they add sugar to the engine, then they are highly likely to add it to the gearbox as well..."

"sugar?"

"No! Add salt!"

Lin Yi checked the gearbox in his hand and said, "The transmission is different from the engine. The engine has oil filter, and there is no melting large particles of impurities and cannot enter the piston part. Therefore, it is necessary to use sugar, a substance that is easy to melt at high temperatures, to degrade the oil, so that the car owner can change the oil more frequently and make more money.

The transmission has no oil filter, and its lubricating oil mainly prevents overheating when the clutch plate is constantly kneaded, so as to prevent normal gearshifting.

Therefore, if you want the owner to change the gearbox oil and clutch plate more diligently, you must use salt, which has fine particles, like sandpaper, to rub the gearbox all the time."

Lin Yi put out a little transmission oil and dripped it onto the toilet paper to hand it to the car owner, "Look, you can see obvious traces of salt."

Lin Yi continued, "Putting sugar into the engine can easily make the engine "hold the tiles". The sugar becomes paste in the engine, causing the engine oil circuit to be poor. The crankshaft bearing and connecting rod bearing cannot be lubricated, and then friction and fall off.

I think there will always be a car repairing the parts in the place you keep, and replace the parts.”

“Yes… It’s true…”

"You have purchased the oil-refining artifact, and we will give you three free maintenance times. If you are relieved, we can exchange one maintenance for one engine or transmission cleaning to help you thoroughly clean the engine and transmission. If you can't believe it, you can also go to other stores to ask."

Lin Yi got up from the bottom of the car and said.

"I think about it."

"You think about it slowly, but I suggest that your car should not be driven first."

Lin Yi went to see the next car again.

“When you drive, do you feel that your engine has become much louder than before?”

"Yeah, there is."

"Your oil hasn't been replaced for too long, and there are too many impurities, causing the engine to wear."

"You have to change the engine oil? You just need to add a glass of water for a car?"

"I suggest you better replace it. We will install the oil-refining artifact here now and provide three maintenance times. You can try it once to see if there is any improvement after maintenance."

"The antifreeze leaks in your car. Have you added tap water to the antifreeze? It's cold in winter and tap water is not resistant to freezing, so you need to change a kettle."

After Lin Yi's dozens of cars were inspected, each car had big and small problems.

Some of these car owners have heard of these problems for the first time, while others have heard of these problems for the first time without asking them to pay.

The best car repairers these days are all in major state-owned automobile transportation companies.

Only a very small number of the car repair departments on the roadside were made by masters from the motor transport company, most of them were apprentices, and even the two knives that they had learned seriously were not done by auto repairs.

The second knife sounds nice, and the thinking is not as rigid as the auto repair master.

To put it bluntly, they dare to make any money.

The owner is with them, for them, you don’t understand this thing anyway, so you can only show it with me. Why can’t I bully you?

Lin Yi saw these problems today, many of them were naturally caused by automobiles, such as neglecting maintenance, design defects, etc. But a large part of them were created by these roadside auto repair shops.

In the past, when there was a problem with the car owners' cars, no matter where they were repaired, they would not be able to tell the cause of these problems.

Because they have made a convention, if I don’t make this money, you will make it.

I said it out loud. If the car owner gets it back, I will be in trouble in the end. Why should I say it?

However, Lin Yi has already set up a strategy and is not afraid of offending others.

Although society in this era was not so legal, there would always be some inexplicable accidents if offended people.

However, Lin Yi felt that making money requires integrity.

He walked back to the old man who had sugar added to the gearbox and salted, and asked, "Does your car need to be handled?"

"Need! Need!"
