is it worth changing your diff oil???

[318ti dan]

hey guys recently purchased my first 318ti (very happy with it so far) but basically I've done a full service changed the gearbox oil aswell so I was thinking I may as well change the differential oil now but is it worth it ??? if so what oil should I use I'm not bothered about price because I don't like cheap nasty oil its a just a standard diff but if any of you could help me I would gladly appreciate it thanks and looking forward to hearing from you

I'd change the fluid just so you know it's been done.
I've been using 75w90 Red Line
Not sure if you need 75w90 or 75w90ns.

It should be changed regularly. I change mine every 30k, sooner if the car sees any track time.

Red Line 75w90 is what you need. 2 Quarts.
