Oil Filter Buying Guide: Getting the Right One

Why the oil filter matters

Your oil filter traps the metal, dirt, and carbon that build up in engine oil. A cheap or wrong filter can bypass early or clog — both are hard on your engine.

What to look for

• Correct fit for your engine (thread size, gasket, length).
• Media quality — synthetic or blended media filters finer and lasts longer than basic cellulose.
• An anti-drainback valve if your filter mounts sideways or down, so oil does not drain out overnight.

How often to change it

Replace the oil filter at every oil change — conventional oil every 3,000 to 5,000 miles, synthetic every 7,500 to 10,000.
