The most common method to loosen a stubborn oil filter is to use an oil filter wrench (pliers).
Here's a more detailed breakdown:
-
Oil Filter Wrenches: These are specialized tools designed to grip the oil filter and provide leverage for removal. Several types exist:
- Cap-type wrenches: These fit over the end of the filter and require a socket wrench or ratchet.
- Band-type wrenches: These have a metal or fabric band that tightens around the filter as you turn.
- Pliers-type wrenches (oil filter pliers): These feature jaws that grip the filter body.
-
Step-by-Step Instructions:
- Position the Wrench: Place the appropriate oil filter wrench around the filter.
- Grip Securely: Ensure the wrench has a firm grip on the filter.
- Turn Counterclockwise: Apply steady pressure and turn the wrench counterclockwise. This is the direction that loosens most oil filters.
- Check for Looseness: Once the filter is loose, you should be able to unscrew it by hand.

Troubleshooting a Very Tight Filter:
- Try a Different Wrench: Sometimes, switching to a different type of wrench provides a better grip.
- Tap the Filter: Gently tap the filter with a hammer and screwdriver. This can help break the seal. Be careful not to puncture the filter.
- Puncture the Filter (Last Resort): If all else fails, carefully puncture the filter with a long screwdriver and use it for leverage. Be extremely cautious when using this method, as it can be messy and potentially dangerous. Wear gloves and eye protection.
Important Considerations:
- Always work in a well-ventilated area.
- Wear gloves to protect your hands.
- Have a drain pan ready to catch the used oil.
- Dispose of the used oil and filter properly.
- Consult your vehicle's service manual for specific instructions and torque specifications.
