What Are the Three Filters in Car Maintenance?

[SanSawyer]

Three filters refer to the oil filter, air filter, and fuel filter. Regular maintenance of these three filters plays a significant role. Their function is to filter out impurities in the oil, air, and fuel, preventing these impurities from entering the engine and affecting its normal operation. Car maintenance tips: 1. Air filter: Proper installation of the air filter can reduce wear on parts such as cylinders, pistons, and piston rings. Generally, it should be cleaned every 5,000 kilometers and replaced every 10,000 kilometers. 2. Oil filter: Proper installation of the oil filter prevents impurities from mixing into the oil during the use of the internal combustion engine, avoiding wear on moving parts and clogging of oil passages. When changing the lubricating oil, the oil filter must also be replaced; otherwise, it will affect the quality of the lubricating oil. The replacement cycle for oil and oil filters is generally 5,000 kilometers. 3. Air conditioning filter: The car air filter is mainly used to filter impurities in the air to prevent them from being sucked into the engine. Since the car engine is a very precise component, the presence of impurities can cause damage. Moreover, if the air filter is not replaced for a long time, it can lead to insufficient engine air intake, reducing engine efficiency and power. The replacement cycle for car air filters is generally 20,000 kilometers or six months.

I've driven for over a decade and changed countless 'three filters' - they are the air filter, oil filter, and fuel filter. The air filter manages the engine's air intake; if you don't change it for too long, the filtering material gets clogged like a quilt, making it hard for the engine to breathe. Once, I skipped changing the air filter for 20,000 km to save trouble, and the throttle response became sluggish with the engine making gurgling noises. The oil filter is a good partner with engine oil; it must be replaced every time you change the oil, or metal debris will accumulate in the engine. The fuel filter is trickier, hidden near the fuel tank to deal with impurities from low-quality gasoline. I've experienced a clogged fuel filter causing poor fuel supply. These three components really need frequent replacement. Don't slack on regular maintenance - check the air filter every 10,000 km and replace the fuel filter every 40,000 km for peace of mind.

When it comes to the three essential filters in car maintenance, we're talking about the air filter, oil filter, and fuel filter. The air filter prevents dust from entering the engine, the oil filter removes metal particles during oil circulation, and the fuel filter blocks impurities in the gasoline. Regular replacement is absolutely crucial. Given my driving habits where I often drive on dusty roads, I need to change the air filter every 8,000 kilometers – otherwise, excessive dust entering the engine accelerates wear. The oil filter requires the most frequent changes, needing replacement with every oil change to prevent quick contamination of fresh oil. The fuel filter can last longer, up to 30,000 kilometers, but never refuel at questionable gas stations as poor-quality fuel contains more damaging impurities. While car maintenance can be costly, replacing these three filters is far cheaper than engine repairs.

Maintaining the three filters refers to the air, oil, and fuel filters. Whenever I visit the repair shop, the mechanics always emphasize this—poor air filter replacement can lead to engine carbon buildup, a dirty oil filter affects lubrication, and a clogged fuel filter can even make starting the engine difficult. I generally follow the maintenance intervals suggested in the manual, with the air filter being replaced most frequently. During summer when willow catkins are everywhere, I have to check it extra. Although DIY replacement is a bit troublesome, changing an air filter myself can save dozens in labor costs. Paying extra attention to these three during maintenance is particularly helpful for the car's condition.
