That sounds about right. dalon, if you fill at 3/4 of a tank, you'll likely put near 11 gallons in it. Strictly running the numbers, you might expect closer to 12.5, but that won't be the case. As I stated before, the gauge does not drop in a linear fashion. When the gauge shows half, you'll still have more than half of your tank's total capacity on board.

"... Something tells me that whatever the owners manual says is not exactly true. I will fill it up when I get to 3/4 of a full tank in the next day or two and see how many gallons I pump, then multiply that by 4 to determine the amount of gallons that the car approximately takes."
 
As for filling up at the 3/4 mark and multiplying by 4, I do that, too, often going 150 miles to the 3/4 mark cruising steadily at 60 mph. From fill ups after 300 miles, I know that 150 miles at the 3/4 mark means that my Forester is getting 30 mpg.
 
Therefore 150 miles has used 5 gallons. Since the tank reads 3/4 at that point, I multiply by 4 like you, and that determines that my Forester holds 20 gallons. Which is a lot more than the Owners Manual says.
 
But, as someone pointed out, the gauge is far from linear, and 3/4 is far from 3/4.

Oh, sorry, I said 3/4 of a tank and meant 3/4 of a tank used, so the gauge would be at the 1/4 mark.

And why exactly would the manufacturer list a false number
 
I can assure you that the capacity listed is correct. I can also assure you that the gas guage is far from linear. I can go 200 miles and the gauge is still at the halfway mark but the low fuel light will come on before I hit 300 miles.
 
I've also gotten to within a 1/2 gallon of running out in my Forester (listed capacity minus gallons pumped) and you could tell is was starting to run on fumes. BTW, this is not a recommended practice for most people

Incompetence!
 
Seriously, automakers make mistakes all the time in brochures. Toyota lists 2 different figures for my Sienna.
 
Welcome back, Frank! Long time no see!

And they also make running changes and may or may not document them.
