Toyota blue washer is good, can be used multiple times, at least 2x. It is just ridiculously expensive from local German dealership. So, I go easy Autozone Dorman brands that I had been using for years for multiple unlimited oil change.
Amazon has the fake stuff. So I just by the blue felt washer from the dealer.
Btw, one side of the washer has thicker felt layer and it is supposed to face the drain pan.
Perhaps this is also why the washer is often stuck against the pan.
