My 09 Smart was leaking oil at the drain plug. I changed my oil today and the plug was stripped out when I went to reinstall it. Appears previous owner/dealer put Teflon tape on the threads to try and stop the leak. I had already purchased an OEM plug/screen so I know it’s not that part. Its looking like it’s the aluminum pan that’s stripped. My question... do I need an OEM pan or will a cheaper one work just as good?
