Can the oil filter not be replaced?

Oil filters need to be replaced regularly. Long-term failure to replace them can lead to vehicle malfunctions. The oil filter is designed to remove debris, gum, and moisture from the oil, delivering clean oil to various lubrication points. Here are some details about oil filters: 1. Oil filters generally have three levels: the oil pan strainer, the primary oil filter, and the secondary oil filter. 2. The oil pan strainer is installed in the oil pan before the oil pump and usually uses a metal mesh design. 3. The primary oil filter is installed after the oil pump and is connected in series with the main oil passage. It mainly includes metal scraper types, sawdust filter types, and microporous filter paper types, with the microporous filter paper type being the most commonly used today. 4. The secondary oil filter is installed after the oil pump and connected in parallel with the main oil passage. It mainly includes microporous filter paper types and rotor types.
Not changing the oil filter is definitely not an option. I've been driving for over a decade and have suffered the consequences in this regard. The filter acts like a guardian for the engine oil, responsible for trapping impurities, metal debris, and other contaminants to protect the engine from damage. If you don't replace it, the filter gradually clogs up, restricting oil flow, leading to insufficient lubrication inside the engine, accelerated wear of components, and ultimately causing premature engine failure. Once, I tried to save money by skipping the filter replacement, and it resulted in engine problems that cost me four to five thousand yuan in repairs—something I deeply regret. My advice is to replace the filter every time you change the oil, typically every 5,000 to 10,000 kilometers. Regular maintenance helps prevent minor issues from turning into major disasters, extends the lifespan of your vehicle, and ensures safer and more worry-free driving. Remember, maintenance is a small thing, but failure is a big deal.
