Hatch92 Posted January 6, 2008 Share Posted January 6, 2008 (edited) it should say one the inside of the gas door. Edit: or on the gas cap. Edited January 6, 2008 by Hatch92 Quote Link to comment Share on other sites More sharing options...
BuddySol Posted January 7, 2008 Share Posted January 7, 2008 (edited) It should be 91 or higher. It can run on lower octane, but it's not recommended by Honda. EDIT: More like Honda recommends that you run 91 or higher. Edited January 7, 2008 by BuddySol Quote Link to comment Share on other sites More sharing options...
