Terry's sounds more likely, I doubt that mileage will be possible.
My FJC gets between 14 and 20 (I check every tank). I take care of my stuff and don't drive over 70. The 14-15's were deer lease trips this winter (some slow driving and dirt roads). The 20 was vacation to Colorado last summer. The average is usually 16-17 to be fair I do have 33" M/T tires on it.
For reference information the wife's Murano will get 24-25 on the highway road tripping but the normal combined is about 20.
