Well I messed up. I performed the first oil change on my 2015 570 and inadvertainly forgot to put the crush washer back on the drain plug (it fell in to the used oil and I didn’t see it until I was disposing of the used oil)
Should I drain the oil and put the washer back on? Or Will I be ok until my next oil change? It isn’t leaking but I want to make sure it is safe to do.. I’m leaning towards draining the oil and putting the washer on and just pouring the drained (new) oil back in.
