Can I Replace the Oil Filter Every Two Oil Changes?

The oil filter can be replaced every 20,000 kilometers. Below is an introduction to oil filter-related information: Accumulation of impurities: When the vehicle reaches 20,000 kilometers, the oil filter will be filled with impurities, affecting normal oil filtration. This can lead to poor engine lubrication, necessitating immediate replacement. At this point, the impurities in the oil filter are nearly saturated, so it's best not to wait until 20,000 kilometers to replace the oil filter. While it is theoretically possible to replace the oil filter every two oil changes, it is still recommended to replace the oil filter with every oil change. Reason for changing with oil: Replacing the filter every two oil changes is not ideal for the vehicle. After a certain mileage, the oil filter accumulates many impurities. If new oil is added without replacing the filter, the new oil can quickly become contaminated. Therefore, it's best to replace the oil filter with every oil change. Additionally, in most cases, the oil filter should be replaced every 5,000 kilometers. However, vehicles using high-quality, long-life oil can extend this interval to 8,000-10,000 kilometers or even more.

Well, from my experience, changing the oil without replacing the oil filter every time? That's a no-go. The oil filter's job is to trap contaminants like dust or metal shavings in the engine oil, protecting internal components from wear. If you only replace the filter every other oil change, it'll be overloaded long before that. Dirt buildup will restrict oil flow, leading to insufficient engine lubrication. The result? Premature part aging, even catastrophic failures like seized pistons or bearing damage. Repair costs can easily exceed thousands – not worth saving a few bucks on a filter. Remember, regular maintenance is key. The manufacturer's manual emphasizes simultaneous replacement – developing this habit saves both hassle and money in the long run. Don't lose big by skimping small – engine failure is no joke after all.

I think it's normal to save a little money, but changing the oil filter every other time is really not appropriate. The filter spins in the oil every day, absorbing all the impurities. If you only change it occasionally, the accumulated dirt can easily clog the passages, reducing oil flow and starving the engine of lubrication. This is like risking thousands in repairs to save a few dozen bucks. Think about it—if the engine overheats and breaks down, how troublesome would it be to get stranded on the road? I always change both at the same time, protecting the car and ensuring peace of mind while driving. During maintenance, take a quick look—don’t procrastinate. The filter isn’t expensive, so safety comes first.

Changing the oil filter only every other oil change may seem convenient, but it poses significant risks. The filter works under high temperature and pressure to trap contaminants, and over time it becomes saturated and ineffective, restricting oil flow. This can silently wear down internal engine components, potentially causing unusual noises or reduced power. Don't cut corners—replace the filter with every oil change to ensure proper lubrication. It's a low-cost, simple maintenance step that prevents major repairs and keeps your vehicle running smoothly.
