Is it okay not to change the oil filter?

No, the oil filter is an important component in the engine lubrication system and needs to be replaced regularly. More information about the oil filter is as follows: 1. How to replace the oil filter: Use a specialized wrench to open the oil filter and perform a secondary release. After all the oil has drained completely, use the wrench to install the new oil filter. 2. The oil filter is also known as the oil purifier. Its function is to filter out impurities, colloids, and moisture from the oil, delivering clean oil to various lubrication points. 3. If the oil bypasses the filter and directly enters the lubrication circuit, it will carry impurities present in the oil into the friction surfaces of moving parts, accelerating wear and reducing the engine's lifespan.

I really don't think skipping the oil filter replacement is an option, because the filter is designed to trap dust and metal particles in the engine oil. If left unchanged for too long, the filter can get clogged, preventing proper oil circulation, which increases friction between engine components, causes severe wear, and might even lead to engine failure. Once, I forgot to change it and drove just over 1,000 kilometers—the engine noise became louder, acceleration felt sluggish, and upon inspection, it was full of sludge inside, costing me several thousand to fix. My advice is to replace the filter every time you change the oil, typically every 5,000 to 10,000 kilometers, and always choose reputable brands to ensure quality. Regular maintenance helps your car run longer and more fuel-efficiently—don’t risk major repairs to save a few bucks on a filter. A car is a precision machine; proper upkeep gives peace of mind.

After driving for so many years, the oil filter is one of the key components, and not replacing it will definitely cause problems. The filter is specifically designed to capture impurities in the oil, preventing them from damaging the engine internals. If not replaced, the filter will become clogged, leading to increased oil pressure, accelerated oil aging, and faster wear on piston rings or bearings. Over time, the engine may be completely ruined. I’ve personally seen a car that didn’t change its filter and seized the engine after running less than 10,000 kilometers. The owner regretted it deeply and later spent tens of thousands of yuan to replace the engine. I recommend everyone develop good habits—always replace the filter when changing the oil, and choose durable materials to extend its lifespan. Simple maintenance can prevent major issues, and a reliable car is essential for safe driving.

Not replacing the oil filter poses significant risks and may lead to engine failure or even stalling. When the filter clogs the oil passage, insufficient lubrication can cause components to overheat and fail, potentially resulting in a dangerous breakdown on the highway. Engine oil collects debris during operation, and without filter replacement, it becomes ineffective, allowing the oil to get dirty and accelerate wear. I strongly recommend always replacing it—inspect it during every maintenance service. The filter itself is inexpensive and easy to replace; delaying the replacement could lead to higher costs later. Maintaining your vehicle is a fundamental responsibility, ensuring the lubrication system runs smoothly for worry-free driving.

As a budget-conscious car owner, I believe skipping oil filter changes doesn't actually save money and carries high risks. While filters only cost a few dozen dollars, not replacing them may save that small amount, but the oil gets dirty quickly and damages the engine - repairs cost at least thousands. For example, a friend of mine didn't change his filter, resulting in abnormal oil pressure and a 7,000-8,000 yuan engine overhaul. Regular filter replacements extend oil life, reduce contaminant buildup, and protect internal components. Just change the filter with every oil change, following the manual's recommended interval (don't exceed 10,000 km). Smart saving means small investments to avoid major losses - keeping your car running longer is the ultimate economy.

Not changing the oil filter is a no-go, I've learned this the hard way through daily commuting. When the filter gets clogged, oil flow becomes restricted, leading to reduced engine efficiency, sluggish acceleration, and increased fuel consumption. It's especially problematic in city traffic jams, where sudden stalling can cause real trouble. Replacing the filter is a standard procedure during every oil change - quick and simple to ensure smooth lubrication system operation. Skipping it allows contaminants to accumulate in the oil, accelerating wear and shortening engine life. Repair costs would far exceed the filter's price. I strictly change mine every six months, keeping my car running smoothly. Proper maintenance makes driving more reliable and worry-free.
