Differential Fill Bolt Washer - Disposable ?
#11
These washers "crush" a bit because they are made out of soft aluminum alloys. They are not like crush washers on spark plugs. Designed to smoosh to specific point, to help seal the combustion chamber. This is why every new spark plug comes with new washers.

These are crush washers. One-time-use. Torque to spec. I think they're less than 50¢ and the dealer will usually just hand them to you without charge. The dealer puts new washers in so the customer doesn't come back with a leak -- or no bolt at all. Why short-cut to save 50¢

As mentioned above, this is just a washer for the FILL bolt. It's not under a lot of stress. It's not going to leak. We're not talking the oil bolt washer.
I know we're all anal about our s2000s (and even I ask a lot of stupid questions on here ), but where have all the men gone? Seriously.

I'm guessing that some time in Honda's history of making engines they encountered a problem with corrosion on the fill bolt and using a copper washer corrected it.

They are supposed to be one-time use. I bought my washers in bulk from HandA for a very reasonable price. I've gotten away with re using washers on my own car but when it comes to customer cars I do it by the book.

you are always suppose to change the drain/fill plug washers, but i have probable change my diff fluid over 10 times and i have never change the washer and it never leaks.

Given that it is made of copper it begged me to ask the question - Why is the differential fill bolt washer different than all other washers on this car ?

The transmission has an oil pump, the diff doesn't
