i do my own oil changes.

i brought my 2015 mazda3 to the dealership for a recall.
they did their usual 360 degree check (or whatever they call it) in addition.

the service rep said the mechanic found slight oil leaking and suggested that i replace the drain plug/washer.

i can see it not being tight. just tighten it, right?
but to buy a new one and replace? ???

How does an oil drain plug/washer fail?

You can replace the awful Hex plug with a 17mm bolt. The dealers tend to over torque the plugs.

I had use a locking vice plier & ratchet hex to remove the bolt. It is unbelievable there was a slow leak. Crush washer was installed*
