Depends if you use dino oil or synthetic.
When you reset your FSS ( after oil & filterchange ), there should be @ 15 k kilometers on the display.
Depending on your type of driving ( yes the computer keeps track of it ), you can check the "count-down", whenever you want, to see what's remaining.
Btw. I use Mobil 1 0W 40, and change it every 10 k kilometers.
