I am assuming you mean 'dropping of of F' not E. If true, it sounds like
you aren't always topping off to the same level when you fill up. Many
cars
will let you 'stuff' in an extra gallon after the pump automatically shuts
off. The pumps' shutoff point vary wildly from one to another. You need
to
use the same pump at the same station if you want to use the fall off
point
from F as a guide. Personally just recording the mileage and fuel usage
should be far more accurate.
As to the varying mileage, does anyone else drive the car? Their driving
habits may be quite different than yours. My 19 year old son destroys!
our
mileage, as you can well imagine......
