No, it does NOT have that big of a tank. It is in fact 11 gallons. This is not the wagon model.
Actually, I wrote this review and my car is a Subaru Impreza Outback Sport Wagon with the 2.2 liter engine and automatic transmission. Currently 193,534 and still going strong.
According to my owners manual the back cover states: Fuel Capacity 13.2 US Gal (50 liters, 110 lmp gal). Of course I don't let it go completely empty before I fill up, so I'm only using about 11.5 - 12 gallons before I refuel. 12 gallons of gas x 33 MPG highway = 396 miles on one tank.
I agree with everything you said, but why do you think a 97 is OLD?
My god! For Subaru's a 1997 isn't all that old.
My friends who "buy new" laugh at me for not joining their moronic "new car club". I laugh at them every time they take their new "worry free" cars in for repairs.
Totally makes me laugh!
I've never even been to a Subaru dealer (except for the occasional trip to the parts counter for the o-ring in the oil pump), yet my wife and kids and I have put a combined (well over) 600,000 miles on our various Subaru's over the last 10 years. We had to abandon Volvos after it became obvious their 5 cyl engine was unrepairable.
Subarus with AWD have replaced Volvo's in our family. We miss our Volvo's, but not all that much to tell the truth. Subarus have filled the void no problem.
We live in deep California snow near a ski resort (over 600 inches this year), and we spend a lot of time in 114 degree Arizona summers. Subi's heaters are great and the A/C too. All we want is a car that is reliable and easy to fix when something does need attention.
Subaru fits the bill. But I really don't think a 97 is all that old.
The tank size of a 1997 Subaru OBS is 13 gallons / 50 litres, which would again make your fuel economy around 30 MPG. Beats my max 28 MPG experience though.
