post your latest differential fluid change

[Oliveoil2]

Valvoline 75w90 in 2021 Crosstrek. Super easy!

Only 20k ish miles on the car and the fluid was quite dark with a good amount of suspended debris. The magnet was fully covered in 1/8” of sludge metal flakes. Very glad I did it now rather than wait till 30k mile service.

Which diff? Or was this the tranny?
