An old saying I have heard is to duct tape an egg to the gas pedal and then you have to drive without breaking the egg.
I don't recommend actually doing this, but the idea is to be smooth and easy on the gas pedal which gives you better gas mileage. Driving style might not be the cause of your bad gas mileage, but it is just a tip that I use and thought I would pass along.

If you are inventive, you could tape the egg in a longitudinal way to the accelerator and it would be ok, since that is the strongest axis on the egg. But your point is well taken and true ;-)
check your brakes. rear drums index if you stop quickly while moving backwards. if you park uphill on a steep driveway brakes can index when you back out and stop. happened to me while on a job-site with high grade. lost power, terrible gas mileage, engine knock slightly during acceleration. initial thought was bad gas. however, transmission was standard so it was easy to discern presence of additional/abnormal friction coasting with clutch in. i jacked-up vehicle and tested each wheel for rotation. brakes were so tight i could barely turn one rear wheel with the tire on. noticed brake pad dust and heat-enduced discoloration on wheel also.

I would look at the engine controls first, specifically the oxygen sensor. Many times, this sensor gives false "lean" readings, which causes the computer to try and compensate by adding more fuel. The extra fuel in the mixture means less $$ in your wallet.

so what engine size is it, what year and what was your gas mileage before? How does it run/idle?
