I went 270 miles and had about/little more than a 1/4 tank left (hard city driving, with mucho idling, still pretty good at about 25mpg in the city). Filled it up, about 11 gallons. Then drove out of town and back on back roads hauling butt. Did over 130 miles and burned less than a 1/4 of a tank. I think zetecs get better gas mileage the faster you go, to a certain point anyways, but I definitely don't think 55-75 is the zetecs sweet spot, gotta go a bit higher, though under 100.
