How often should the oil filter be replaced?

[SebastianLynn]

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.
