I bet there is a big difference between the FWD and the TWD models.
The best I ever got in my 4X4 is a little over 18MPG and that is all highway miles using the cruise control.
Maybe it is because mine is the older 2000 model.
I can't believe some are getting 24 with their newer 4X4.
I am lucky if I get 18 on the highway and 14 around town. :redbrick:
edit: This is per the built in mpg calculator, which assumes my tires are about 10% smaller than they actually are, so when I calculate by hand it is a little bit better than the above numbers.
