The Durango averaged about 16.5lit/100km overall but if I worked really hard, I could get it down to 13.5it/100km on a highway run if I kept the speed to a max of 85-90 km/hr on the cruise control.

The Aspen has averaged a calculated 13.8lit/100 over 7130 km (at the last fill) without even trying. Been running studded snow tyres over the past 5000 km and supposedly the sticker rubber compound costs around 1-2lit/100km in extra fuel. Saw AVG Consumption figures on the display that were in the mid 10s about 10 days ago while taking it really really easy on the highway (lots of patches of snow and ice over the road) with a 40-60km/hr tail wind.
