What is the recommended usage interval for engine cleaners?

Engine cleaners should be used every 30,000 to 50,000 kilometers, and do not require overly frequent cleaning. The function of an engine is: to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the expanding gas to push the pistons and perform work. The working principle of an engine is: 1. Mixing air and gasoline in a specific ratio to form a combustible mixture; 2. The intake stroke draws the mixture into the cylinder, where it is compressed, ignited, and burned to generate thermal energy; 3. The high-temperature, high-pressure gas acts on the top of the piston, driving it to perform reciprocating linear motion, which is then converted into rotational mechanical energy through the connecting rod, crankshaft, and flywheel mechanism.
Regarding the usage interval of engine cleaners, my experience suggests that applying it every 10,000 to 15,000 kilometers is appropriate. For my decade-old SUV, I add a bottle of cleaner every two oil changes. Before long highway trips, pouring half a bottle into the fuel tank helps reduce carbon buildup caused by excessive idling. Note: avoid adding cleaner immediately after an oil change as it wastes the fresh oil's cleaning properties. For frequent driving in dusty areas, shortening the interval to 8,000 kilometers is advised to prevent sludge from clogging critical components. Regular engine cleaning ensures smoother power delivery.
