The data I posted above - is mostly city driving.
My daily commute is about 14.5 miles each way, only 3-4 miles of 55mph, rest is across town with stop lights and stop signs, and some 35-45mph roads.
Most of the time I drive for fuel economy - engine brake & coast up to stops/traffic signals, where possible.
Same route for nearly 17 years, so I know the traffic & light patterns well.
I actually get better mpg in city than hwy, especially with the 98 SE.
