1600 km with a tank filling?

It was assumed some time ago how many kilometers you could travel with a tank filling according to the on-board computer. On the occasion of yesterday’s World Sprit-Spar-Day (you have to let each word melt on your tongue!) AND on the occasion of the current fuel prices I have sometimes frustratedly tested exactly that. I have filled my elk at an expensive blue tank in Burscheid and Zockelt to Bielefeld. In fact, I reached in the meantime an average consumption of 4.8l according to BC. And the highest of the feelings was actually after already driven 345 kilometers a residual range of over 1300 kilometers. Unfortunately I am not the XC fan and can not photograph so well during the ride so that my proof photos do not make much. BUT: Did you find similar (exceptional) phenomena? And what is now the actually maximum possible range? My nerves will unfortunately not get this driving style a k omplette tank filling. That’s why I will probably never be able to do it myself.
