I just did a full tank highway trip with very little city/offroad driving and got 19mpg on my 1996, 33's and 260k miles. Not bad really. But city is not great. Like stated, 12-14mpg is what i get city.
The 96 was rated pretty low, around 15 city, 18 highway for the v6 but in 97 the ratings jumped too 19 city 23 highway.
