The oil filter cleans dirt and particles from the oil that may cause damage. An easy way to remember to change your oil filter is to replace it at every oil change or every other oil change. Oil filters are inexpensive and range from $5 to $20 depending on the vehicle.

You can ask a licensed mechanic to change both your oil and filter at the same time. If you want to change your oil and oil filter yourself, be sure to purchase the correct filter for your engine and follow the filter manufacturer’s instructions.
