I don't know as I don't have a speedometer, but on a recent run in very cold weather on very icy roads in 4X4 the whole time I burned $13 worth of gas to go 130 km (as measured on the odometer of a friend's Arctic Cat). Gas was just under $1.30 per liter, so I burned close to 10 liters to go 130km. In American, that's about 2.6 US gallons to go 80 miles
