Should I be worried about cheap oil change?

Anyways, I went to go pick up my car and the oil change was merely $31. So I asked the service manager what oil they used and used a synthetic castro oil. I didn't mind too much at the time but now I'm getting quite concerned that they used cheap (maybe even recycled) oil since the dealership only charged me $2.71 per quart. Should I go ahead and switch it out with Royal Purple or Mobil 1 since the dealer forced me to synthetic?
