Does Cylinder Cleaning Require an Oil Change?
2 Answers
Car cylinder cleaning does not require an oil change, as carbon deposit removal does not affect the engine oil. Precautions for cleaning internal carbon deposits: Open the oil filler cap, pour in the entire bottle of cleaner (mixing it with the old oil), then close the oil filler cap. Start the engine and let it idle for 10 minutes before turning it off. Cleaning internal engine carbon deposits helps dissolve sludge, gum, moisture, and metal debris deposits inside the engine, reducing contamination of new oil and extending the engine's lifespan. Method for cleaning internal engine carbon deposits: The process for cleaning internal engine carbon deposits is very simple. Before maintenance, add a bottle of engine internal cleaner into the oil filler port and let the engine idle for about 10 minutes. Then, immediately proceed with maintenance by changing the oil and oil filter. Car owners can purchase engine internal cleaners online themselves.
As a mechanic with 20 years of experience, I'm telling you that you must change the oil immediately after an engine flush. The cleaning agent dissolves carbon deposits and gum residues, and these tiny particles will mix with the oil. If not flushed out, it's like running the engine with 'sand' inside, which accelerates wear on piston rings and cylinder walls. It's similar to cleaning algae from the bottom of a swimming pool when changing the water! Our standard procedure is to drain the old oil first, inject the cleaning agent, let the engine idle, then drain all waste fluid again before finally adding new oil. Skipping the oil change to save money will kill your engine fast—repair costs could cover ten oil changes!
