How Often Should Engine Cylinders Be Cleaned?
3 Answers
Engine cylinders should generally be cleaned every 30,000 to 50,000 kilometers. The cleaning methods for engine cylinders and the effects of not cleaning them are as follows: Cleaning Methods for Engine Cylinders: Engine cylinder cleaning involves removing carbon deposits inside the cylinders. There are three methods to clean carbon deposits from engine cylinders: first, adding a fuel cleaner to the fuel tank; second, using a fluid supply device for cleaning; third, disassembling the engine for cleaning. The first two methods are more economical and safer, while the third method is more thorough but also more expensive. Effects of Not Cleaning Engine Cylinders: Excessive carbon deposits can alter the original structural parameters of the engine, reducing engine power and increasing fuel consumption. In severe cases, it can also cause engine knocking, abnormal acceleration, and damage to pistons and crankshafts. The accumulation of carbon deposits will continue to thicken, leading to a vicious cycle and eventually requiring a major engine overhaul.
I've been driving for over ten years. With frequent traffic jams during city commutes, the engine tends to accumulate carbon deposits. I usually check the cylinder condition every two to three years or every 30,000 kilometers. If I experience difficulty starting the engine or lack of acceleration power, I'll go for a cleaning. The cleaning primarily removes internal carbon buildup to restore combustion efficiency. On a daily basis, I use higher-quality fuel to reduce the risk of fuel line clogging, combined with gentle driving habits, which can extend the intervals between cleanings. It saves money and ensures safety—don't wait for minor issues to become major problems.
I work in car repair, and there's no fixed interval for cylinder cleaning—it depends on your driving habits. Frequent short trips in the city lead to more carbon buildup, so cleaning every 30,000 km is advisable. Highway driving produces less carbon, so going up to 50,000 km is fine. Also, consider fuel quality and air filter condition—clean when issues arise to avoid wasting money. After cleaning, you'll notice a clear power boost. I recommend getting it done at a professional shop to avoid damaging parts by DIY attempts.
