Actually we can cruise over 400 miles (19 gallons @ 22 MPG); nevertheless I wish it were more. I would like a cruising range at least 450 miles. I always did think the MDX had a rather skimpy fuel tank for an SUV. A 23 to 25 gallon tank would be great.gregguy said:I am a bit surprised about you feelings on the gas tank. I just got my MDX last Friday and on my first tank (mostly highway driving) it lasted about 350 miles without the gas light coming on.
