What else needs to be replaced when changing the engine oil?

When changing the engine oil, the oil filter also needs to be replaced. Replacing the oil filter: The oil filter is a component that filters the engine oil. Engine oil contains a certain amount of gum, impurities, moisture, and additives. During engine operation, metal shavings generated by friction between parts, impurities from the intake air, and oil oxides are all filtered by the oil filter. If the oil is not filtered and directly enters the oil circuit, it will adversely affect the engine's performance and lifespan. The role of the oil filter: It filters out harmful impurities from the oil in the oil pan, supplying clean oil to moving parts such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning functions, thereby extending the lifespan of these components.
When changing the engine oil, I always replace the oil filter as well because the old one may have accumulated impurities. If not replaced, the newly added oil can quickly become contaminated, affecting engine lubrication. Additionally, I make it a habit to check the air filter at the same time. If it's dirty, I replace it immediately since it affects the air quality entering the engine. A dirty air filter can increase fuel consumption and reduce power. For high-mileage vehicles, I might also inspect the spark plugs. If they've been used for 20,000 to 30,000 kilometers, it's time to replace them to avoid ignition issues that could cause engine misfires. Overall, these maintenance steps help prevent future problems and ensure smooth vehicle operation. I often drive long distances, so this routine helps avoid the embarrassment of breaking down midway.
When changing the oil at home, the most basic step is to replace the oil filter. Otherwise, just changing the oil would be a waste of effort, as a clogged filter can contaminate the new oil and accelerate wear. I often take this opportunity to clean or replace the air filter, especially if living in a dusty area, as a dirty air filter can make the car noisier and slower to accelerate. Additionally, replacing the cabin air filter before summer is a good idea, as I worry about stale air causing allergies. Taking care of these small details can enhance the driving experience and reduce future repair costs, making it a cost-effective habit for me.
