"Your car has serious carbon deposits. Use a fuel cleaner to clean it, otherwise it will damage the engine." When you are at a gas station, you may have encountered gas station staff telling you this. It is said that this kind of fuel treasure can reduce carbon deposits in the engine, save fuel and protect the environment. But what about reality? You'll know after reading it. ?

First of all, if we want to know whether the Fuel Treasure is useful, we need to know what the Fuel Treasure is and what its specific function is. Fuel treasure is a common name for fuel additives. Its function is to solve the carbon deposit problem caused by insufficient combustion of gasoline when the engine is running. It also helps improve the atomization effect of gasoline when the engine is working, and can also reduce cylinder wear and exhaust emissions.

The most direct way to verify whether this fuel treasure really has the effect of removing carbon deposits is to test the actual car. The model tested today is the Volkswagen Golf 7th generation. It looks very cool and bright. , are you all attracted by the appearance? I have driven 76,478km so far, and I used a cleaning product once when I drove 50,000 kilometers

The method of this actual car test is still the same as before, check it out first Check the carbon deposits on the spark plugs and engine combustion chambers, then add the mustard green fuel oil we tested, fill up a tank of fuel at the gas station, and drive a tank of fuel, then go to the repair shop again to see the combustion after cleaning. What changes have occurred in the room?

When I came to the repair shop, I explained my intention to the repairman and immediately removed the cover. It was obvious that he was very professional.

The first thing to remove is the spark plug, which can be said to be a black layer of carbon deposits.

The most important thing is to check the carbon deposits in the combustion chamber cylinder. The result of looking through the endoscope is that the inside of the cylinder is pitch black and the original metal surface can no longer be seen, but the carbon deposits are not thick. Maybe Because it has been used once before.

Even if it is used once after driving 50,000 kilometers, there will still be a lot of carbon deposits.

First add the entire bottle of mustard green fuel treasure we tested this time into the fuel tank, and then add 50ml of gasoline to the car. This will also allow the fuel treasure and gasoline to be fully mixed.

The next step is to run out this tank of fuel, escape from the congested road section, and go to the highway. After two days, the tank of fuel has finally been run out. I can’t wait to see the effect of the fuel treasure in removing carbon deposits. What happened.

Kilometers before test: 76478km

Kilometers after test: 77115km (total driving distance: 637 kilometers)

When I come to the repair shop again, I still have to dismantle the car. First, look at the cleaning of the spark plug

The cleaning effect of the spark plug before and after is obvious. After cleaning, the metal surface has been exposed.

Let’s take a look at the combustion chamber that we most want to see. After using the fuel treasure, the carbon deposits on the piston head in the cylinder have been significantly improved, and the metal at the edges has gradually been exposed.

After analyzing this before and after, the carbon deposition in the cylinder has been greatly improved after using the fuel treasure. This time, the cleaning effect of the fuel treasure is quite good, and the cleaning ability is relatively strong.

Warm reminder: For models with long mileage and serious carbon deposits, be sure to clean them carefully and consult customer service in advance to avoid unnecessary trouble.
