n00b question but how often do you change the differential oil? I take delivery of my s2000 tomorrow. It is a MY00 and has ~11k miles on it. I'm sure it has never been changed and it would make me happy and at ease knowing there is fresh fluid in there.

Once a year,in my case,wich is less than 6000 miles.

I use LE-607 and change annually.

Recommended to change by 10k miles, so you're right on track at 11k. Change it right away, then as mentioned, annually after that (although this is probably not necessary, but diff health is very important so why risk).
