How Often Should the Oil Filter Be Replaced for Optimal Performance?
2 Answers
It is optimal to replace the oil filter every 5,000 kilometers or every six months. Here is some information about oil filters: 1. Definition: Oil filters can be categorized by structure into replaceable, spin-on, and centrifugal types; by their arrangement in the system, they can be classified as full-flow or bypass. 2. Function: The oil filter is located in the engine lubrication system. Upstream of the oil filter is the oil pump, and downstream are the various engine components that require lubrication. The oil filter's role is to remove harmful impurities from the oil coming from the oil pan. 3. Structure: The oil filter removes 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. This provides lubrication, cooling, and cleaning effects, thereby extending the lifespan of these components.
Having driven for so many years, my experience tells me that the oil filter replacement interval isn't a rigid rule. For the first few years of a new car, I usually change the oil filter every 5,000 km when replacing the engine oil to avoid clogging and lubrication issues. After prolonged use, if you're using synthetic oil and high-quality filters, you can extend the interval to 10,000 km. But this only applies if you mainly drive in urban conditions - in dusty areas or for frequent long-distance trips, it's better to check at around 7,000 km. Once I procrastinated too long and the clogged filter caused louder engine noise, costing me nearly 2,000 yuan to repair the oil pump. So don't skimp on this - safety first. The manual gives the most accurate maintenance schedule, as requirements vary by brand (Japanese cars tend to be more lenient, German cars stricter). Regular filter inspections can prevent major issues.
