Darn, I would be happy if I can get 20mpg. I'm sure trip to Vegas will get me up to 25mpg.

Something ain't right! Most get around 19 city/27 hwy/21 combined.

It's time to start doing some diagnostic work. Check for stored codes. Any mods? Chips, intakes, aftermarket exhaust can all negatively affect gas mileage. Clean air filter? Vacuum leaks? Sticky brake caliper or emergency brake cable? Tire pressure? Are you using premium fuel?
