Just a bit of info for everyone, possibly for comparison. We drove the wife's 96 Outback (2.5-Automatic) from Tulsa to Cincinnati and back last weekend. Drove up Thursday, came back Sunday. The car was loaded with three kids, two adults, one small dog, and luggage (I could still see out the back though, very important!). Anyway, total mileage was 1,678 miles, and average fuel economy was 25.83 mpg. Five tankfuls of 26.33, 27.47, 23.84, 27.44, 24.08 mpg each. Normally we ran down the highway between 75 and 80 mph.
(PS- King's Island is cool!)
