If I were you I'd go see your dealer and get a manual from him. The gas should be 87 octane. That's what the engine is designed to drink. The oil shouldn't be changed until 10,000 miles under normal use, or 5,000 miles under extreme use. I drive around Atlanta, so I changed mine at 5,000. Don't change it at 500...There are no "metal shavings". You won't even feel like your Honda broke in until 25,000 miles or so...Read your manual.
