Drove my new Rubicon to the northwestern part of my country ( Iceland) few days ago. I mostly spent my time on around 50 to 70 mph ( legal limit is only 60mph ) on the roads here. Drove total of 800miles during the trip , over mountains, very bad tracks and dirt roads. Surpriced of how little fuel it uses. The trip computer gave me 7.5L/100km or somewhere close to 30mpg.
