What Crush washer to use with the oil drain bolt?

Copper, alluminum, or vinyl

pros and cons
I bought a pack of 5 or so vinyl ones. I change them with every oil change, and I haven't experienced any leakage yet. They are packaged as oil drain plug washers, so I picked them up, and they work fine.

You'll have to find a size that work with your drain plug, going off of pure memory (please let me know if I'm wrong), but I think the oil drain bolt size is an M14-1.5 (only the m14 part is important when buying a washer).

From the factory, they come with copper, so how much oxidation and damage could really occur with using a copper crush washer? Depending on your climate, I doubt a whole lot of oxidation could really occur. The most important thing is that you change the washer with every oil change.

incorrect, OEM Honda are aluminum in construction.

Use aluminum. I've read that if copper is used, oxidation can occur because of the two different metals.
correct.

I bought a 100-pack for $10 on ebay.

I have like 20 of them, but I've been using the same one from the factory for like 4 oil changes now. No leaks. They aren't really a crush washer either, at least not like the ones that I HAD to replace every time on my Suby.
