Classification of oil filters: There are full-flow and bypass types. Below are the detailed introductions: 1. Full-flow oil filter: Most modern automobile engines use full-flow filters of the filtration type. The oil enters the filter from the periphery of the filter element, flows to the center of the filter, and then exits through the outlet into the engine's main oil passage. As the oil passes through the filter element, impurities are trapped on the element. 2. Bypass oil fine filter: Bypass oil fine filters come in two types: filtration and centrifugal. Filtration-type filters face a contradiction between filtering capacity and flow capacity, while centrifugal-type filters offer advantages such as high filtering capacity, large flow capacity, and being unaffected by sediment. Therefore, automobile engines mostly use centrifugal-type oil filters as bypass oil fine filters.

As a car mechanic enthusiast, I must say there are quite a variety of oil filters. Common ones include the spin-on type, where the entire housing can be unscrewed for replacement—simple to operate and suitable for beginners. Then there are the cartridge types, which only require replacing the filter element without changing the housing, making them eco-friendly and material-saving, though they require special tools and a bit more DIY skill. Less common types like centrifugal filters separate impurities via centrifugal force, offering longer maintenance intervals but at a higher cost. Magnetic filters use magnets to capture metal particles, helping to extend engine life. Synthetic filters used in high-performance vehicles offer finer filtration and superior high-temperature resistance. Each type has its own characteristics, and choosing the right one can significantly enhance engine performance. I love studying their durability under different driving conditions—that's where the fun of car enthusiasm lies.

After driving for ten years, I've concluded that the type of oil filter is quite crucial. The spin-on type is the most commonly used—it's convenient to replace during an oil change. The cartridge type requires a skilled mechanic, and I always remind them to check the filter element during maintenance. There's also the magnetic type, which is great at capturing metal particles. When choosing a filter, make sure it matches your car model—don’t skimp on quality, or your engine noise will increase. For regular family cars, a spin-on filter is economical and sufficient; if you drive long distances often, consider a high-performance version. Though small, regular replacement of the oil filter saves hassle and money, preventing breakdowns on the road.

Engine oil filters can be roughly divided into several types: spin-on, cartridge, and magnetic. Spin-on filters are the most common, easy to install, and suitable for beginners; cartridge filters are more environmentally friendly but slightly more complex; magnetic filters are particularly sensitive to metal impurities. Choosing the right one can protect the engine and reduce wear. For daily driving, just make sure it matches your car's specifications and driving habits.
