What Happens If You Don't Change the Car Filter?

Not changing the car filter will affect the engine's air intake, leading to weak vehicle acceleration. The car filter refers to an accessory that uses filter paper to remove impurities or gases. Filters are categorized into: oil filters, air filters, and fuel filters. The method for replacing an oil filter is: 1. Remove the drain plug to drain the engine oil; 2. Clean the drain plug and tighten it; 3. Loosen the oil filter with an oil filter wrench and remove it; 4. Apply engine oil to the O-ring of the oil filter; 5. Screw on the new oil filter.

As a car owner, I've personally experienced the consequences of forgetting to replace filters. That time when the air filter hadn't been changed for too long, dust completely clogged the mesh. While driving, I clearly felt the engine struggling, poor acceleration, and fuel consumption inexplicably skyrocketed. When I finally took it to the repair shop, the mechanic said restricted airflow was damaging the engine piston rings, nearly requiring a major overhaul costing thousands. Since then, I've strictly followed the manual's recommendation to replace the air filter every 10,000 km or six months to avoid bigger troubles later. Additionally, not changing the oil filter allows contaminants to accumulate in the oil, accelerating engine wear - in severe cases, it might even cause engine seizure. A clogged fuel filter can also lead to poor fuel delivery, causing frequent stalling. These are no trivial matters - don't lose big by skimping on small things.

In my years of dealing with cars, I've observed the chain reactions caused by neglecting filters. A failed air filter allows dust to enter the engine directly, affecting combustion efficiency, reducing power output, and increasing exhaust emissions that pollute the environment. Not replacing the oil filter for a long time leads to impurities circulating and wearing components, shortening engine life and resulting in costly and time-consuming repairs. Fuel filter issues are even more serious, potentially causing fuel pump burnout or nozzle clogging, which will definitely double the repair bill. I advise friends to follow the manufacturer's manual for regular maintenance. Replacing filters costs only around a hundred yuan each time but can prevent major issues. Also, check the cabin air filter, as it affects the air quality inside the car. Not replacing it timely can lead to bacterial growth, and even opening the windows won't easily disperse the odor.

Neglecting filter replacement can cause significant harm. A clogged air filter allows impurities to enter the engine, resulting in reduced power and increased fuel consumption. Failure to replace the oil filter leads to internal component damage and potential burnout. A malfunctioning fuel filter may cause fuel line blockage and engine stalling. Ignoring the cabin air filter deteriorates interior air quality, potentially triggering allergies or unpleasant odors. Don't underestimate these issues - prolonged neglect creates major problems. I routinely inspect filters myself, replacing them when dirty. It's an easy DIY task with low cost that protects your health.
