I've got a 2007 CTS V6 2.8 (auto-transmission) with very high gas consumption rate - 14 -16 L/100KM range, which is way higher than specification. (Today I drove the car and noticed the on-board computer shows 16.3 L/100Km). I told my dealership the "problem" when I drove in for regular maintenance and they didn't find anything wrong. Is this normal? Appreciate any help on this.
