My tank is half full but I am not putting in any gas, I'll wait two more weeks and then I'll fill it when it's bone-dry. It has 22.5 gal capacity (usually I put in 21 or less), and now with the price way down, I can do it without having to use my CC twice. When it was $4, and given their $75 CC limit, I could only put about 19 gallons, and then it would slowly cut it off, which is really annoying, since I always calculate the accurate MPG between fillings and want to fill the tank all the way until the "click" sound is made.
