Mazda CX-9 2009 model. 4.1 km per liter. But in practical terms its a full tank for every 4 days of daily commuting to work for me. GULP ! (Q.C. to Makati). Time to load gas again.
I think your City driving FC is better than a local car magazine's Mazda CX-7 road trip recorded FC of only 5++ km/L from Manila to Subic, considering majority of the distance travelled are via expressways.
