What are the two types of oil fine filters?

The classification of oil filters: full-flow and bypass. The oil filter is one of the four filters, the other three being the air filter, cabin air filter, and fuel filter. The function of the oil filter is to remove impurities from the oil, protecting the engine from wear. The filtration principles of oil filters can be divided into three categories: mechanical separation, centrifugal separation, and magnetic adsorption. Below is a detailed introduction: 1. Mechanical separation: Commonly seen as mesh filtration, where the filter material has small holes of a certain size on its surface. Solid particles in the oil larger than these holes are trapped on the outer surface of the filter material. 2. Centrifugal separation: Involves passing the oil through a high-speed rotating rotor, where impurities are thrown towards the inner wall of the rotor by centrifugal force, thus separating them from the oil. 3. Magnetic adsorption: Uses permanent magnets to attract iron particles in the oil, preventing them from circulating and damaging engine components.
I just checked into the matter of the oil fine filter, and actually, it comes in two main types: one is the paper filter element type, and the other is the centrifugal type. The paper filter element is more common and can be seen in most cars. It uses specially treated paper to filter out fine impurities in the oil, but the downside is that it needs to be replaced regularly because the paper can get clogged and affect performance. Generally, you need to replace the filter every time you change the oil. The centrifugal type is smarter, using high-speed rotation to fling out impurities, making it much easier to clean and maintain. Although the initial manufacturing cost is higher, it’s more durable. Personally, I think the choice depends on the car’s design. Modern cars mostly use paper filter elements for simplicity and cost-effectiveness, but larger vehicles or high-performance cars might come with centrifugal types. This thing is crucial for the engine’s lifespan, so you’ve got to maintain it on time—don’t wait until the oil gets dirty to think about fixing it. Remember, paying attention to the details prevents big problems, and you’ll drive with more peace of mind.
As someone who frequently tinkers with car repairs, I'm well aware that oil fine filters are divided into two types: paper filter elements and centrifugal ones. Paper filter elements are simple and cost-effective to install—just buy and replace them directly. However, their downside is that they clog up quickly and must be replaced regularly as per the manual. Centrifugal filters use rotational technology to separate impurities and can be reused after cleaning, saving resources. Although the initial installation cost is higher, they are cost-effective in the long run. In practice, paper filters are suitable for daily commuter cars, while centrifugal filters are more effective for heavy machinery or modified vehicles. Don’t slack off during maintenance—check the filter condition promptly to avoid reduced oil flow leading to engine overheating. Experience has taught me that understanding different types can save money and extend engine life, and DIY work also requires a grasp of basic principles.
