This is interesting. I was at the same dealer about three weeks ago to
get an oil filter and washer for my '93 90. At first, the guy came
back with the same aluminum thingy. I said, "Hey, it's supposed to be copper!"
(assuming he was trying to gyp me with some aftermarket washer). I went
back, rumaged around and came out with the copper one I had expected...

As far as problems with dissimilar metals, I believe the oil pan on the
V6 is aluminum too. The drain plug, however, may be different.
