How often should I replace my oil drain plug?

Troubleshooting
Drain plug leaks oil after installation
Ensure the copper seal ring is present and correctly seated. Check that the sealing surface on the oil sump is clean and free from debris. Verify that the plug has been tightened to the correct torque specification. If the leak persists, the oil sump threads may be damaged, or the plug itself may be faulty.
Drain plug is difficult to screw in
Ensure you are threading the plug in by hand initially to avoid cross-threading. Check that you are using the correct plug for your vehicle model. Clean the threads on both the plug and the oil sump.
Stripped threads on the drain plug or oil sump
If the plug threads are stripped, the plug will need to be replaced. If the oil sump threads are stripped, a more extensive repair may be necessary, such as using a thread repair kit or replacing the oil sump.
