You can use premium, but if the manufacturer doesn't specify that it's required and the engine has no knock, why bother?

http://www.hyundaisonatamanual.com/sonata-3-fuel_requirements.html Pasted from owners manual: Introduction / Fuel requirements Your new vehicle is designed to use only unleaded fuel having a pump octane number ((R+M)/2) of 87 (Research Octane Number 91) or higher. Other words regular 87 is fine but they used premium 91 during engine testing

Absolutely! While many will argue that it may not be needed - I personally have found that the 2.4L Sonata that I'm driving runs extremely smooth on Chevron Premium. This last tank, I'm trying a tank full of Sam's Club station premium - and, so far, no issues. But with GDI - it's good to consider "top tier" fuel to reduce the amount of deposits - especially on valves over time since GDI engine designs are more prone to carbon build up than the multi-port fuel injection designs with other types of engines.

Higher octane lets the computer advance timing. Possible hp gain or torque. My volvo would use 87 but jammed on 92
