Regular Vs. Premium

[BabyBlue2010]

Which is better? Can the Aveo handle premium?

[mf70]

On the basis of experience with other cars, I assume that regular is actually preferred.

there is absolutely no reason to run premium in your aveo.

[jj79]

wouldn't running premium fuel cause problems such as incomplete burning, leaving reminants and causing damage in the long run?

[petrified.rabbit]

potentially yes, but i think the ecu would adjust and cut fueling until it was "burning" effectively. But that will sap power, and burning effectively does not mean running effectively.
