First service after 6 months at 6870 miles. Went to the Honda dealer as I pre-purchased the maintenance package (Honda Care Sentinel) for 3 years. Glad I got the maintenance package because this forum proved that oil changes are more frequent than a standard ICE. If oil changes are needed every 6 months, I forecast about $500 of oil changes for the 3 years. Cost: free - $0 out of pocket.
