Mazda extended warranty, and 60K service

:
06 LS MS6
07 BM GT (shell has been struck from the roll)
Soooo, Do I have to have my official 60K service done at a Mazda dealer? Or, can I find a local shop to bless it?

I really don't feel like pullin all these mods just for a service, I mean if it breaks, and I need to beg for warrranty coverage thats different, but for a fluid change, (which means they throw out my fresh ford juice) and belt insp. would rather not if possible
