Whether to change the car oil filter depends on the actual situation. Here is an overview of the reasons for changing the car oil without replacing the filter: If the filter is not changed, the dirt in the oil filter will re-enter the oil circuit, affecting the normal operation of the engine. Here are some precautions for changing car oil: 1. Choose the right oil for your vehicle. 2. Change the oil as much as possible when the engine is warm, and drain the oil completely. 3. The oil filter must be replaced when changing the oil. 4. The amount of oil added should be appropriate, based on the oil dipstick. 5. After adding the oil, start the engine and check for any leaks in the components. Here are the steps for changing the oil: 1. Use a jack to lift the vehicle, locate the drain plug, and loosen it to drain the oil. 2. After unscrewing the oil filter, place a container underneath. 3. Replace with a new oil filter and add new oil.

From a safety perspective, I believe the oil filter is absolutely not something you can skip replacing. It specifically filters out dust and metal debris from the engine oil, protecting the engine's normal operation. If left unchanged for a long time, a clogged or failed filter will allow dirty oil to flow into the engine, accelerating internal wear. Soon, the engine becomes prone to overheating, increased noise, or even sudden stalling—especially dangerous at high speeds when headlights won’t help. I recommend replacing the filter every time you change the oil, roughly every 5,000 to 10,000 kilometers depending on driving habits. For example, frequent city driving in traffic jams warrants more frequent changes. Regular prevents major issues—spending a few dozen bucks now can save thousands in major repairs later. Safety should always come first; don’t gamble with your life.

From an economic perspective, skipping the oil filter replacement is simply a waste of money. You might save a small amount now, like 30 or 40 yuan, but when the filter gets dirty, its filtration efficiency drops, and the new oil gets contaminated faster, accelerating engine wear. The result could be severe engine damage, costing thousands or even tens of thousands in repairs—wouldn’t that be a much bigger loss? I’ve even seen some owners’ cars scrapped after just five years due to neglecting oil and filter . Sticking to replacing the filter every six months or with each oil change ensures the car runs smoothly, maintains stable fuel consumption, and saves significant costs on fuel and repairs in the long run. Additionally, a well-maintained car fetches a higher resale value, offering a better return on investment. Car maintenance requires foresight—don’t lose big by skimping on small things.

For vehicle performance, neglecting to replace the oil filter directly impacts the driving experience. A clogged filter obstructs oil flow, leading to insufficient engine lubrication, sluggish acceleration, unstable power during uphill climbs or high-speed driving, and significantly increased noise. I've personally noticed that with a well-maintained filter, the engine runs smoothly with much less noise. Modern cars are equipped with numerous sensors that trigger warning lights at the slightest issue, which can be quite annoying. It's recommended to replace the oil filter in sync with oil changes, typically around every 8,000 kilometers, but always check the manual for specifics. Keeping the filter clean ensures the car drives as smoothly and enjoyably as when it was new.

In terms of , changing the oil filter is a basic must-do. Simply replace it every time you change the oil—it's quick and easy. Skipping this step allows accumulated contaminants to pollute the entire oil system, shortening engine life and potentially causing further issues. I routinely perform simple checks, like inspecting for cleanliness, following the manufacturer’s recommended frequency. Don’t forget—regular maintenance reduces repair needs, which is crucial for daily tasks like school runs. DIY options are plentiful with online tutorials and accessible tools, or you can visit a nearby shop for a small service fee—either way, it saves major headaches.

From the experience of an old car owner, not changing the oil filter is absolutely unacceptable. When I was younger, I got lazy once and didn’t change the dirty filter for over six months. Suddenly, the engine started making a rattling noise. When I took it in for repairs, I found severe piston wear, costing nearly ten thousand to fix. The lesson was profound: saving small money invites big disasters. Now, I change the filter every time I change the oil, with a frequency of every 5,000 kilometers, especially for aging cars where diligence is even more crucial. Use quality-assured filters—cheap ones are fine, but don’t be greedy for bargains. Develop good habits, and your car will last longer and give you more peace of mind.
