Before you begin
In this guide, I will demonstrate how to perform an oil and oil filter change for a 2012 Ford Focus. This guide is applicable to all body and trim styles of the same year. It is recommended that you change your oil every 4000 - 6000 miles and that you change your oil filter approximately every 10000 miles. You should use 5W-20 oil whenever changing or adding oil. Different manufacturers will have different name and part numbers for their compatible oil filters, so you should consult the parts counter at your auto parts store to determine which ones will fit your vehicle. A carjack is not necessary to perform this procedure, the drainage bolt and oil filter can be easily reached underneath the front bumper of the car.
