I bought a sega. Just ran 5000 kilometers. Engine carbon deposit. Excuse me, how to deal with the master! Does carbon deposition have a great influence on the engine?

It shouldn't be a big problem for a new car to be 5000 kilometers. Don't care too much. Organic carbon is normal, and gasoline always leaves traces. Don't trust the 4S store to let you add this and that, it's of little use! Pay attention to the following points when using the car: 1. Don't always drive at a low speed. If you drive to and from work in the urban area, it is suggested that after the running-in period, you can pull up the speed between 2 and 4 to impact the intake branch pipe. What do you mean, the shift should have been started at 2000, but now it can be delayed to around 3000 or even higher, as long as the sound is not annoying. High speed is fine, but the engine is louder. 2. If you have the opportunity to run the expressway, you can also follow the instructions in 1. 3. Better synthetic engine oil can replace all additives and will not harm the engine. Some additives are very corrosive. 4. It is very important to replace the original air filter, oil filter and gasoline filter on time.
