What Are the Effects of Not Changing the Air Filter for Two Years?
2 Answers
Not changing the car's air filter for two years can have the following main effects: 1. If the air filter hasn't been replaced for two years, it is likely already clogged, which will obstruct airflow, reduce the engine's air intake, leading to decreased engine power and a significant increase in fuel consumption. 2. Additionally, a dirty air filter will reduce its filtering efficiency, allowing small sand particles and impurities to enter the engine. Over time, these contaminants can cause wear and damage to the cylinder walls, pistons, piston rings, and valves. 3. Extension: In reality, the replacement interval for the air filter should be analyzed based on actual conditions. Under normal city driving conditions, it can be replaced every 20,000 kilometers.
As a car owner with pretty good driving habits, let me share my experience. I usually pay close attention to vehicle maintenance, but once I forgot to change the air filter for two years, which led to problems. At first, I just noticed the car had weaker power and slower acceleration. Later, fuel consumption increased significantly - I calculated it cost me at least 10% more in gas money.
The air filter mainly protects the engine by filtering out airborne impurities. When it gets dirty, it blocks airflow, forcing the engine to work harder - like trying to run while wearing a gas mask. The impact might be less noticeable for city driving, but if you frequently drive on highways or dusty roads, dust can enter the engine cylinders directly, wearing down internal components and shortening engine life.
When I took my car for repair, the technician warned that prolonged neglect could cause more serious damage like increased carbon buildup. So here's my advice: it's best to check and replace the air filter annually or every 10,000 km. This simple maintenance can prevent extra costs and potential hazards.
