Review on 🔍 Dorman 090-081CD: Oversize M12-1.75 S.O Oil Drain Plug with 15mm Head Size - High-Quality Search by Justin Anderson

Nylon washer, no rubber. Started leaking because I couldn't tighten the screw enough to get a good seal. I almost snapped the bolt trying to tighten it enough so it wouldn't leak. Buying a second one and using the rubber washer from the previous drain plug would be great. The threads of the oversized screw are easily strayed during the threading process. My strands were about medium length. Tip: Spend a lot of time refilling so you have a few chips instead of ripping off more.
