I get tired of spending too much time to remove some Toyota, Nissan and Subaru drain plug washers. The Nissan/Subaru ones truly crush and you have to use a thin flat screwdriver to remove them from the drain plug. On the Toyota washers, both the new coated aluminum ones and the old fabric ones, I find myself having to scrape them off the oil pan when some of them seem to get fused to the pan. For both M12 applications, I've bought some flat copper washers (COC China) on Amazon for about 35 cents each that are 12 mm ID by 20 mm OD by 1 mm thick and I'm hoping they make oil changes a bit easier and quicker.
