If you need examples of this, here it is In Sonic Advance when he came back to Earth a few days later still in Super Form.

Earlier my friend Supremekai did a calculation...That if Sonic had a couple thousand rings he would only last for two days. A Few days is longer then two days...Sonic is able to maintain the form as long as he wants.

Also again even in cutscenes it shows that Sonic does not need rings of any sorts to transform into Super Sonic he is constantly using the emeralds.
