My Mercedes-Benz S320 has been fueled with 92 # gasoline from a private gas station for a long time, resulting in an increase in engine carbon deposit, and some spark plugs often burn out. What should I do? Hello, regarding Mercedes-Benz, I suggest to remove the carbon deposit first. The most common method is to remove the throttle, clean the front and back of the throttle with carburetor, and then dry it with cotton cloth. Then there is the cleaning of carbon deposits inside the engine. We can do it before changing the oil. Open the oil cover, add the cleaning agent, mix it with the old oil, and run for ten minutes. Air intake system cleaning: buy a bottle of air intake system cleaning agent, pour it into the liquid storage tank of special cleaning equipment, connect the air intake system, and suck the cleaning agent into the air intake by vacuum to achieve the purpose of cleaning. Spark plugs burn out because the engine has too much carbon, which leads to the accumulation and carbonization of unburned mixture on the spark plug electrode, which leads to the ignition and damage of the spark plug. If you are not a professional maintenance person, it is recommended to go to the local dealer or maintenance station to check the specific problems. I hope I can help you and hope to adopt it!
