Try thiese tips:
1. Keep tires inflated to recommended pressure and within one pound of each other. Low tire pressure can cost 1-2 mpg.
2. Dragging brakes can decrease fuel economy. Regular brake inspections will help you keep your car rolling and stopping.
3. Synthetic lubricants have been proven to greatly reduce friction in engines and differentials. Reduced friction means better mileage and more power. Dirty oil can cost up to 0.5 mpg in fuel economy.
4. Keep air filter clean, or upgrade to a high-flow filter element. Add fuel injector cleaner to the gas tank every 5,000 miles to help injectors vaporize fuel properly. A dirty air filter can cost up to 2 mpg in fuel economy.
5. Regular tune-ups are crucial to engine efficience. Replace spark plug wires every 50,000 - 60,000 miles, depending on how severe your driving conditions are. A complete tune-up can yield as much as 10 mpg!
6. Acceleration requires more horsepower and uses additional fuel. The harder you accelerate, the more fuel you use. Go easy on the gas.
7. Air conditioning is one of those parasitic losses that can be eliminated by simply turning off a switch. This is a big one - usually woth 1-2 mpg.
Additional Tip: Improper wheel alignment or a dragging brake could double the required horsepower, cutting fuel economy by up to 20 percent.
Hope this helps!

The model and year would be useful, but generally speaking, there are a few other things in addition to the filter and tuneup the other responder mentioned.
Tire inflation, how fast you drive, maladjusted parking brake, ECU in a weird mode due to a bad sensor, a lot of city driving in a hilly area, a roof rack or a big "Pizza Delivery" sign on the roof, are all things that can affect mileage.

I'm suprised nobody said check the spark plugs. That would be the best guess. Think about it fuel just goes in and doesn't ignite it goes to waste resulting in the other pistons supplying all the power.

Try this one.
Drive like you would if your grandma was in the car with you.
Any car says it gets 30 mpg or 50 mpg, but if you don't drive it right, your not going to get anything out of it.
I know I did that with my ford escort.
My dad was getting 45 with it, My friend was getting 19.. Yeah so Drive gentally

First, measure the gas mileage accurately and then check your oxygen sensors and air filter.

Try taking it in for a tune up and change of filters, if that does not help you may have a big problem!!
