We just got it a month ago and have actually only filled it up twice! My husband drives Prii for work and those get 50 mpg. Ours is still breaking in (it's got 650 miles on it now), but hopefully we'll get 500-600 miles per tank!filly77
betcha you never complain at the pumps! i'd like one of these someday. how many miles do you get from a full tank?
