How often should the oil filter be replaced?
3 Answers
Oil filters should be replaced every 5,000 to 10,000 kilometers. It is recommended to replace the oil filter whenever changing the engine oil, as contaminants in the old filter can reduce the viscosity and cleanliness of the new oil, affect oil circulation speed, and potentially damage the engine. The oil filter (short for oil cleaner) is one of the three major filters in a vehicle. Its primary function is to filter the engine oil, improving its cleanliness and lubricating properties. The oil filter supplies clean oil to components such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning effects. This helps minimize engine wear, ensures optimal performance, and extends the lifespan of these components.
I've been driving for over a decade, and I always check the oil filter during every oil change. Generally speaking, it's most reasonable to change it every 5,000 to 10,000 kilometers, depending on your vehicle model. For my SUV which mainly drives in urban areas, I need to change it every six months. If you don't change it regularly, the filter will get clogged, allowing impurities in the oil to enter the engine, causing wear or oil burning, which can be costly to repair. A friend of mine once forgot to change it, and half a year later, the engine made loud noises upon starting, resulting in spending thousands to replace the engine—what a huge loss. Now, I set a phone reminder to go to the maintenance shop every 5,000 kilometers for a change and take the opportunity to check the entire lubrication system to avoid trouble. Don’t skimp on the oil filter either; poor-quality ones don’t filter properly and can damage the engine. Using original or well-known brands gives peace of mind. In short, regular maintenance is the way to save money and protect your life.
I'm always passionate about car maintenance. The typical replacement interval for oil filters is every 5,000 to 8,000 kilometers. If you have aggressive driving habits, like frequent hard acceleration or driving on rough roads, you should change it at 5,000 kilometers. Last month, I replaced mine myself, and after 8,000 kilometers, the filter was deformed with oil as black as ink. Delaying replacement leads to poor filtration, allowing contaminants to accumulate and cause engine overheating, potentially resulting in breakdowns in severe cases. Don't forget to regularly check the oil level; if you notice rapid oil consumption, it's time to consider changing the filter. The cost of replacing an oil filter is low, just a few dozen yuan, far more economical than a major engine overhaul. Developing this habit ensures a longer engine life.
