Can I Only Replace the Oil Filter Without Changing the Engine Oil?

[DelRicardo]

No, you cannot only replace the oil filter without changing the engine oil because the oil filter and engine oil are designed to work together. Here is some information about oil filters and engine oil: 1. The oil filter removes impurities such as dust, metal particles, carbon deposits, and soot particles from the engine oil, supplying clean oil to moving parts like the crankshaft, connecting rod, camshaft, turbocharger, and piston rings, providing lubrication, cooling, and cleaning effects. 2. Engine oil, also known as engine lubricant, is a crucial factor in car maintenance. It directly affects the operation of the vehicle's heart—the engine—and influences the overall condition and lifespan of the vehicle. Inside the engine, there are many metal surfaces that move and rub against each other. High-quality lubricating oil can reduce wear on engine components and extend the engine's service life.
