I’ve been doing my own oil changer over 50 years. Never had an oil leak because of the washer on the drain plug. Now on '06 Nissan that I have, uses a ‘crush washer’ that leaks. Never heard of crush washer before this. Why not use a regular flat washer?

Did you use a new one ? They are one time use items.

get to your local dealer and buy a pack of them

my dealer sells them for $0.20 a piece, I buy 10-pack at a time

it is no point in reusing crush washers

I’ve been doing my own oil changes for years and never come across a crush washer (on a drain plug) until I changed the trans fluid recently in my wife’s 2013 Toyota. The drain plug had an aluminum crush washer. I didn’t replace it and of course it leaked. I put a fiber washer on it, couldn’t find the right size aluminum crush washer locally. It’s fine now.

As for why some manufacturers use a crush washer rather than a drain plug with a rubber or nylon gasket on it, I have no idea.

My 09 Kia Sedona uses a crush washer on the oil drain plug. It is very soft aluminum and comes packaged in with my oil filter. I always open the box at the parts store to be sure it’s in there. Haven’t had a leak yet.
