What Does the Term 'Three Oil Filters' Refer To?
3 Answers
Three oil filters typically refer to the regular maintenance items for a car: the oil filter, fuel filter, and air filter. Details about the three oil filters: The oil filter, also known as the oil grid, removes various impurities from the oil to ensure the proper functioning of the lubrication system. Air filters come in two types: dry and wet, and they are devices designed to remove particulate impurities from the air. Fuel filters are categorized into diesel filters, gasoline filters, and natural gas filters, with their main function being to filter out impurities from the fuel. Functions of the three oil filters: They are primarily used in pneumatic machinery, internal combustion engines, and other fields to remove impurities such as dust, metal particles, carbon deposits, and soot particles from the oil, thereby protecting the engine. They provide clean air to these mechanical devices to prevent them from inhaling air containing impurities during operation, which could increase the likelihood of wear and damage. They also block particles, water, and contaminants in the fuel, ensuring that the precision components of the fuel system are protected from wear and other damages.
I'm an ordinary driver with over ten years of experience behind the wheel. I often hear people mention the 'three filters for engine oil,' which actually refer to the oil filter, air filter, and fuel filter. The oil filter is located in the engine's oil circuit, working daily to filter out metal shavings and dust from the oil, preventing contaminants from entering the engine's core. The air filter manages the intake system, blocking road dust and impurities to ensure the engine doesn't inhale dirty particles. The fuel filter is positioned along the fuel line, filtering out impurities and moisture from the gasoline to ensure clean and efficient combustion. I replace these filters every year during maintenance. If not replaced in time, the engine may become noisier or lose power, especially noticeable during long-distance drives. In severe cases, it might even require an engine overhaul, doubling the cost. For regular cars, replacing them every 10,000 kilometers is sufficient. Don't skimp on this expense—it can extend your car's lifespan by several years.
When I first started learning to drive, I was completely baffled by the terminology. "Three filters for engine oil" refers to the oil filter, air filter, and fuel filter. The oil filter cleans the engine oil, ensuring smooth lubrication; the air filter protects the intake system, preventing dust and debris from harming the engine; the fuel filter removes impurities from the fuel, avoiding clogged fuel injectors. I learned that new car models might not require frequent changes within two years, but older cars need more attention. Otherwise, the car is prone to breaking down, and repairs can be troublesome. Once, I drove an old car that had been neglected for maintenance, and it stalled halfway, wasting time and costing extra money—a lesson learned the hard way. It's best to stick to regular maintenance; it's simple and worry-free.
