I'm more than surprised, that's shocking! How did you equate the mpg? IMHO the only reliable method is:

1) Fill up tank.
2) Clear trip meter.
3) Fill up tank, noting how much gas you're putting in.
4) Divide miles on the trip meter by gallons used.

Using this method, I'm getting 112-14 MPG in everyday light driving. When I did a few hours on the higway, I got about 17 MPG, that was going about 60-70 on cruise the whole time.
