True, in a way, as you don't need to refuel after every jump. A warp scout with the same 20 tons of jump fuel, can travel 5 weeks burning 4 dtons of fuel per week for a total 10 parsecs rather than 2 parsecs. A warp capable Mercenary cruiser using the original jump fuel quantity (168 tons) can travel 3.5 weeks burning 48 tons per week for a total of 10.5 parsecs.
