hi, once again the old topic, which was definitely here already 100 times worked, but I unfortunately could find net. the question is. how much you really save compared SUPER – LPG at the s60 tank volume according to manufacturer for gasoline is 70liter at frank-scan it is called LPG tank 77l but 62l go pure. distance with gasoline which can be travelled are about 800-900km the distance in the LPG operation lies according to frank-scan at 550km cost factor of a tank filling at super = limp 80euron the same with LPG = limp 37euro so you save net really 50 or 55% where it is usually praised everywhere. or is the distance with LPG nevertheless much higher ? p.s.: and if you compare the whole with the diesel it looks even more extreme.
