In the states we might say the clutch "chatters". Regardless, my '98 Miata
developed a clutch chatter that, over weeks, became worse. It turned out to
be the front transmission seal leaking oil onto the clutch. The clutch and
seal were replaced under warranty. FWIW, this happened after I switched to
Red line MTL in the transmission. The dealer told me that it was common for
the seals to fail when synthetic oil was used in the transmission (possible
BS?). They did the work under warranty because the owner's manual said
nothing about avoiding synthetic lubes.

BS. While it's true that switching to synthetic after many years of dino
oil may cause seals to weep, it ain't gonna happen to any Mazda still
under warranty.
I started using MTL at 60k miles, and my tranny doesn't leak. I just
passed 128k.
