Is Engine Intake Cleaning Necessary?
3 Answers
Engine intake cleaning is necessary. Since there is currently no complete method to prevent carbon deposits, if not cleaned regularly, carbon deposits will accumulate endlessly. Once carbon deposits build up in the intake system, it may cause engine shaking, reduced power, and in severe cases, even engine cylinder scoring or seizure. Methods for engine intake cleaning: 1. Bottle cleaning: Also known as non-disassembly cleaning, this method involves introducing cleaning agents into the engine intake pipe via a bottle, where they are drawn into the engine combustion chamber along with the intake airflow. During this process, the cleaning agents clean the engine intake system, especially the throttle and intake valve positions. 2. Disassembly cleaning: Requires removing the engine intake passage for cleaning.
When it comes to engine intake cleaning, I think it's quite necessary, especially for older vehicles that have been driven for three to four years. Carbon deposits accumulating in the intake tract and throttle body can affect the air-fuel mixture, leading to reduced power and increased fuel consumption. Regular cleaning can restore engine efficiency, making the car feel more responsive during acceleration and slightly lowering fuel consumption. I recommend cleaning every 30,000 to 40,000 kilometers, depending on the vehicle's condition—for example, cars frequently driven on short trips tend to accumulate carbon deposits faster. Neglecting cleaning can lead to more severe issues in the long run, such as idle vibration or sensor malfunctions. It's safest to have it done by a professional repair shop, as they use proper tools like drip cleaning and can also inspect the air filter system. Adding a reliable fuel additive occasionally can also help slow down carbon buildup. However, don't fall for excessive cleaning recommendations—new cars in their first couple of years generally don't need it.
I've been driving for over ten years, and whenever I feel the car lacks power during acceleration or the fuel consumption spikes, I go for an intake cleaning. My previous car didn't get cleaned in time, resulting in severe carbon buildup. When climbing hills, the engine would make gurgling noises, but after cleaning, it instantly became much smoother and more fuel-efficient on long highway trips. A mechanic friend told me that carbon buildup can clog the engine, making it work harder—like having a stuffy nose when you're sick. It's not necessary to do it every month, but you should pay attention to signs like rough idling or difficulty starting. The cost is usually around three to four hundred bucks, which is cost-effective and can prevent expensive major repairs later. New cars might not need it early on, but older cars should get it done regularly, ideally around every 40,000 kilometers. Combining it with regular maintenance is convenient and gives peace of mind.
