Can I Change the Engine Oil Without Replacing the Oil Filter?
1 Answers
It is not advisable to change the engine oil without replacing the oil filter. The primary function of the oil filter is to remove impurities from the engine oil. Over time, these impurities can cause blockages. Additionally, a certain amount of old oil remains inside the filter. If you only change the oil without replacing the filter, the new oil will mix with the old oil, reducing the lifespan of the new oil. The oil filter is located in the engine lubrication system, positioned between the oil pump (upstream) and the engine components that require lubrication (downstream). Its role is to filter out harmful impurities from the oil in the oil pan, delivering clean oil to components such as the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, thereby extending their service life.
