Interesting choice of nit picks, the drain plug “gasket” (crush washer) was replaced, the oil filter touching the ground won’t damage it or really pick up any particulates. It’s not as though it was rolled in dirt or mud or anything. As per the Jack stands? The frame rails? Where you jack a car from and can safely secure it? Sorry we’re not some sort of Ferrari/bugatti garage you must be used to working in, and it was painful for you, but the cars just fine. 👍 thanks for your support.
