My Subaru's oil drain plug requires a crush washer to seal. I tried reusing the old washer, but oil dripped out and I wound up having to buy one anyway. Has anybody found a good substitute that can be reused, or is at least cheaper than the $1 a washer that Subaru wants for these.
It's not as though I don't have any ideas - copper washer, O-ring, or even a couple of wraps of 1/16" solder would probably work, but it's nice to hear from the voice of experience.
