Seriously, WTF is going on? I fill up yesterday at a gas station near my university, then I drive home (all freeway miles). After 54 miles of all highway driving my gas needle is already below the 3/4 line and almost at the 1/2 line mark. 54 miles and I use almost half a tank?

I didn't even go into boost at all, and I'm completely stock. Since buying the car a month ago I've already spend $282.55 on gas alone. I seriously have to force myself not to drive the car because it's costing me a fortune.
Estimated 22mpg city and 30mph highway my ass.
