Change the filter
Always change the filter whenever you change the oil. Clean oil + a dirty filter = dirty oil.
- You'll be able to access the old filter from either above or below the car. Place the oil filter wrench around the filter's body. It will tighten itself up when you turn the wrench counter-clockwise to remove the oil filter.
- The old filter may stick initially, but will then unscrew easily. Unscrew it completely and carefully put it aside. It will be full of oil.
- Dip your fingertip in the old oil (convenient) or take a few drops from a new quart of oil (cleaner). Use it to lubricate the circular edge of the new filter, where it will contact the metal engine surface.
- Screw the new filter in with your hand, and tighten it firmly without overtightening--one quarter turn after snug.
