Oil Filter: what it does & when to replace it
The oil filter removes metal particles, dirt, and combustion by-products from the engine oil so they do not circulate and cause wear. It is replaced at every oil change — typically every 8,000–16,000 km or per the maintenance schedule. A clogged filter can trigger the bypass valve, letting unfiltered oil through, which accelerates engine wear. Using the correct filter for the engine matters: thread size, gasket diameter, and bypass-valve spec vary. This is one of the easiest DIY jobs, done with the oil change using a filter wrench and a drain pan.
DIY difficulty: Easy DIY (with every oil change). Always confirm the correct part for your exact build by VIN before buying.
