I am absolutely shocked when I get over 16mpg with my VX! Full to dead empty (the hard way) was 265 miles. That was combo city/hwy. Did 2 back to back trips 150 miles each with no "run-around" miles (so, all highway) and got 16.6 MPG------wooohooo! Speed was 75 and I don't jackrabbit off the line. Only mod is a drop in K&N filter and 285/55 tires (3% difference from stock in diameter). I had this kind of mileage before the tires were installed. When I first got her, I'd get 320 - 340 miles before a fill up, before the idiot light came on. Now 260 and the light is on.
