I have always noticed a GREAT difference between auto and MT mileages. For instance the geo metro's I've owned were different by about 5 or 10 mpg. Automatics have always given worse mileage than MT. Maybe other cars are different.

Also note that your economy will go up as you learn to drive it better so the difference between you and the people getting 70-100mpg will shrink.

There are some people on here with CVTs that are doing better than people with MTs as well. The driver is as big a part of the equation as the transmission.
