Is it necessary to add engine cleaner and protector?

It is not necessary to use them. Cleaning the air filter: The air filter is directly related to the engine's air intake during driving. The manager of a Guangqi Honda dealership told reporters that if the vehicle only drives in the city, the air filter will not be clogged. However, if the car is driven on roads with more dust, special attention needs to be paid to the cleanliness of the air filter. Removing throttle sludge: There are many reasons for sludge formation in the throttle. Some are caused by carbon deposits formed by fuel combustion exhaust at the throttle; others are residues from impurities not filtered by the air filter. Excessive sludge can cause air resistance in the intake, leading to increased fuel consumption.
Whether to add engine cleaner and protector depends on the specific situation. I think if the car has been running for a long time and the engine has a lot of carbon deposits, adding cleaner can indeed help restore some power and improve fuel efficiency. However, it's really unnecessary for new cars—just change the oil on time. Spending extra money and effort isn't worth it. I've driven for over a decade, and well-maintained engines stay clean without additives. Some cheap products might even damage components, so it's not a must. The money saved is better spent on a good filter or checking the cooling system. Don't fall for advertising hype—practice is what matters. It's best to consult experienced drivers before deciding.
