i was one who claimed that... i and spoke too soon (sorry didnt mean to lie) - i did go from full to 3/4 tank getting 70 miles a few times but that does not happen very often and def doesnt happen on any other part of the fuel guage - i would say 240 is much more accurate for me and i have done everything i can think of to improve the fuel efficiency (i also have no suspension mods and ride stock sized high performance street tires)
