From the manual:

All engines are designed to meet all emis- sions regulations and provide excellent fuel economy and performance when us- ing high quality unleaded “regular” gaso- line having an octane rating of 87. The use of premium gasoline is not recommended,
as it will not provide any benefit over regular gasoline in these engines.
