What are the three oil filters?

[Brody]

Oil three filters refer to the air filter, oil filter and fuel filter. The functions of the three oil filters are as follows: 1. Ensure the air entering the engine is clean. There is a lot of dust suspended in the air, mainly composed of silicon dioxide, which is a substance harder than metal. Installing an air filter can reduce the wear of parts such as cylinders, pistons and piston rings. 2. Ensure fuel cleanliness and prevent vapor lock. During the storage, transportation and refueling process of gasoline, it is inevitable that some impurities and water will be mixed in. These impurities will be brought into the fuel supply system and engine cylinders along with the fuel, accelerating cylinder wear. Before gasoline enters the fuel pump, it must be filtered to ensure the normal operation of the fuel supply system. 3. Filter the oil to ensure the normal operation of the engine. During the use of internal combustion engines, mechanical impurities such as dust, metal wear debris, and carbon deposits will continuously mix into the oil. At the same time, the oxidation of the oil by air and combustion exhaust gas will gradually produce colloids in the oil. The mixture of mechanical impurities and colloids will also form sludge, which will not only accelerate the wear of moving parts but also easily cause oil passage blockage. To ensure the cleanliness of the oil, the engine is equipped with an oil filter in the lubrication system.

Speaking of the three filters in engine oil, this is a hot topic in our automotive circle! It mainly refers to three key filters: the air filter, oil filter, and fuel filter. The air filter is responsible for filtering the air drawn into the engine, blocking dust and impurities to prevent clogging of the intake ducts. The oil filter removes metal shavings or dirt from the engine oil, ensuring smooth lubrication and reducing wear. The fuel filter cleans water and particles from gasoline, preventing clogged fuel injectors. I often maintain my car—the air filter is usually replaced every 10,000 to 20,000 kilometers, depending on how dirty it gets from road conditions. The oil filter should ideally be replaced every time you change the engine oil—it saves money and hassle. The fuel filter should be inspected every 20,000 to 30,000 kilometers; don’t delay too long. Neglecting them can lead to increased fuel consumption, engine knocking, or even engine seizure, which is expensive and troublesome to repair. I recommend new car owners develop a habit of regular inspections and buy high-quality filters to keep the engine running strong and long.

As an average car owner, the three essential filters—air filter, oil filter, and fuel filter—play a crucial role in my daily driving. The air filter screens out dust from the air, ensuring smooth engine intake; the oil filter keeps the engine oil clean, preventing lubrication issues; and the fuel filter removes impurities from gasoline, avoiding fuel supply problems. I’ve noticed these filters are inexpensive, but neglecting their replacement can be costly: a clogged air filter may reduce acceleration and increase fuel expenses; a faulty oil filter can accelerate engine wear and shorten its lifespan; and a malfunctioning fuel filter might cause the car to stall. During each maintenance session, I ask the mechanic to check them: the air filter should ideally be replaced annually or based on mileage; the oil filter is renewed with every oil change; and the fuel filter is inspected every 20,000 kilometers. This simple tip has saved me significant repair costs and provides peace of mind on long drives.

Talking about the three filters in oil maintenance, they are the air filter, oil filter, and fuel filter. The air filter prevents dust from entering the engine, the oil filter cleans impurities from the oil to ensure lubrication, and the fuel filter removes dirt from gasoline to prevent malfunctions. Key maintenance points: Check the air filter every 10,000 kilometers and replace it if dirty, the oil filter must be replaced during an oil change, and the fuel filter should be inspected around every 20,000 kilometers. Neglecting them can easily lead to higher fuel consumption or stalling, so don't delay.
