I used the nylon washer and have had NO issues. I don't see what the big deal is that washer must be copper. It's ironic that Nissan would insist on a copper washer but yet still uses failure prone Clutch Slave Cylinders on their Manual transmissions.

I don't use any washer and have no issues. Awhile back I just installed a valve and was done with it. Also a side note magnets don't seem to do much, from the start I did UOA for all my oil changes and over the course of 7 changes iron levels did not drop off any more quickly then the norm.

i rather re-use the old washer vs not using any. no need to add unnecessary wear from friction.

You can reuse them for years. The issue comes when the copper washer get's scared from dirt or the friction over the years. You just need to inspect it and be very clean at every oil change with the plug and pan surface. The copper washer acutally goes face up on the drain plug. Twist it on the wrong way and it will not bottom out on the plug.

If you remove enough metal to make a difference in 100 oil changes (300,000 miles) to weaken the structure......:wtf2:

yah, i just replace it each time. why not, i have a bunch of them already.

i suppose you can go commando if u want. i prefer to do it the normal way...especially knowing that surface should not be scratched by the plug.
hell go ahead and use ur pliers to remove your lug nuts. im sure it can be done.

It's visegrips on the oil drain plug. God I have seen a many.

yeah.. same here. they are very cheap.

I think the real purpose is that the washer would crush and provide proper seal when torque to factory spec. You may have to tighten down more with an already crushed washer and I have heard people stripping the oil pan from too much torque on the drain bolt.

what am i looking at here?

Looks like a Fumoto oil drain valve.

aka a Qwik Valve. Fumoto Valve | Qwik Valve™
