How often do I really need to change my oil filter???

I would change it every 3,000 miles when you change the oil, it makes no sense to change the oil and leave an old filter with 1 qt. of old oil in the engine.How often do I really need to change my oil filter???
everytime you change your oilHow often do I really need to change my oil filter???
every time you change your oil. 3000 miles 3 months
change it everytime you have your oil changed.


every three months or 5,000 kms which ever comes first





If you only change the oil and not the filter, your oil dirties up faster and harms your engine
Depends, every 3 months or so...sooner if you drive a lot.
you should change the filter everytime you change the oil 3,000 miles or 3 months
EVERY 3 MONTHS THE FILTER SHOULD BE CHANGED.............THE OIL SHOULD ALSO BE CHANGED EVERY 3 ALSO UNLESS IT IS SYNTHETIC OIL
