How to Clean Carbon Deposits Inside Engine Cylinders?
2 Answers
Due to prolonged engine operation, residues such as engine oil, dust, and debris can form gummy deposits, leading to carbon buildup. Here are the methods for cleaning internal engine carbon deposits: 1. Open the oil filler cap and pour in the entire can of cleaner, mixing it with the old engine oil. 2. Close the oil filler cap, start the engine, and let it idle for 10 minutes before shutting it off. 3. Replace the engine oil and oil filter. 4. The cleaner dissolves sludge, gum deposits, moisture, and metal particles inside the engine, reducing contamination of new oil and extending the engine's lifespan. 5. The recommended cleaning interval is generally every 30,000 kilometers. Refer to your vehicle's maintenance manual for the appropriate cleaning schedule.
Cleaning carbon deposits inside the engine cylinders is something I've tried several times on my car. The easiest way is to use fuel additives. Carbon deposits are basically black residues left from incomplete fuel combustion in the engine, which can make the car sluggish and increase fuel consumption. My usual approach is to buy a reliable fuel system cleaner, add it to the fuel tank, and then take a highway drive to let the additive dissolve the carbon deposits through the combustion system. Make sure to choose a reputable brand—don't go for cheap options, as they might not work well. After the highway run, you'll likely notice slightly better fuel efficiency and smoother engine response. This method is convenient and can be done at home, but don't expect it to completely remove stubborn carbon deposits, especially in older cars. It's good to do this periodically, about once a year, and pair it with an air filter replacement to prevent new deposits from forming. The key is to buy products from authorized channels to avoid issues. If your car is in poor condition, it's better to visit a professional shop. Overall, this method is quite practical for most people—just give it a try and see the difference.
