Is it necessary to change the oil filter?

[VonDaniella]

Yes, it must be changed. When performing car maintenance, it is necessary to replace the engine oil with qualified products and change the oil filter at the same time. This ensures better usage of the engine oil and effectively filters out impurities within the oil, preventing long-term clogging issues. Below is relevant information about oil filters: 1. Location: The oil filter is typically located in the engine's lubrication system, with its upper part connected to the oil pump and the lower part connected to various components within the engine that require lubrication. Generally, the oil filters used in car engines are non-cleanable disposable filters, so the oil filter needs to be replaced along with the engine oil during maintenance. The oil filter is also one of the car maintenance items, usually requiring replacement every 5,000 kilometers. 2. Function: The role of the oil filter in the engine is to filter out harmful substances from the engine oil, ensuring a good working environment for components such as the crankshaft connecting rod and turbocharger, and providing lubrication and cleaning functions.

I believe the oil filter must be changed along with the engine oil. My over 20 years of driving experience tells you, don’t skimp on such a small expense. The engine oil is responsible for lubricating the engine, and the oil filter is like a mask for the engine, specifically filtering out impurities and metal debris in the oil. An oil filter only costs a few dozen bucks, but if you don’t change it regularly, it will gradually clog up. The accumulated impurities can damage your engine, which is a matter of tens of thousands of dollars. Once, my old buddy stubbornly waited over 20,000 kilometers to change it, and the engine ended up making terrifyingly loud noises. Remember to replace the oil filter every time you change the engine oil during maintenance—this is something you can’t afford to delay.

You can tell by looking at the internal structure of the filter. I've disassembled dozens of old oil filters. The filter paper inside lasts at most 8,000 kilometers before it's clogged with metal particles and sludge, losing its filtering capability. At that point, the oil can only bypass through the relief valve directly into the engine, carrying all the contaminants with it. The most obvious signs are the sudden oil pressure warning light, the engine noise becoming louder, and a noticeable drop in power. Last time, I encountered a customer who didn't change the oil filter for 5,000 kilometers, and it ended up damaging the turbocharger. Honestly, why skimp on something that only costs around a hundred bucks? Changing the oil filter every time you change the oil is basic maintenance knowledge.

Must change it! Never save money on this. I've been maintaining my small car myself, so I know exactly how this works. The oil filter only costs around ten to twenty bucks. Not changing it is like letting dirty oil repeatedly flush your engine. Precision components like crankshafts and pistons are most vulnerable to scratches from tiny metal shavings. Ever seen a coffee filter used for three weeks? That's what a clogged oil filter looks like. I always order oil filters online in advance before each oil change and hand them directly to the mechanic at the shop. This saves time and ensures safety. Plus, modern oil filters come with magnetic rings to capture metal particles—if they're already ineffective, they're just decorative at that point.
