I've got the 2020 and get 16-18 mpg. When the fuel light comes on, I have 7 litres (1.5 gallons) left, my range is 200 kms with about a gallon left. FYI, I've finally figured out a great set up for the Tuner 3's and snowtrackers, took lots of experimenting but the sled now handles as well as any...
