TO let everyone know
....I have a 93 bonneville ssei...its in great condition but in city driving I only get 9 miles to the gallon and in highway driving, 12 miles to the gallon so if you're looking for something good on gas then don't look here. It is supercharged though so its pickup is hte best in my household....I have 5 vehicles.
That is not normal at all!! You should be getting about 18-20 in town and about 27-29 on the highway, something it wrong with your car! A tuneup would be the first thing.
For real Man ....that just worst that Hummer H1
