i just checked mine for the first time tonight. i bought my car exactly a week ago, so i've only been able to test city/MPG once now. i'm taking the SSE to Colorado tomarrow and will test highway/MPG then. btw, i deliver pizza in this car fwiw...i don't drive crazy but i am in a hurry most of the time. meanwhile, here'* what i got:
model: Bonneville SSE
Other Mods?: No, completely stock with 104,000 milles
Best Observed HW MPG: not yet tested...
Average Observed HW MPG: not yet tested...
Best Observed City MPG: 21.1 MPG
Average Observed City MPG: 21.1 MPG
i'm happy with that; my 3.1 MPFI 5-speed Cutlass only managaed 18-19 MPG/city (when it was NA) and my Turbo GTS is around 21-22 MPG/city and i need to try to stay out of boost to achieve those numbers. that'* not too bad considering this SSE has a bigger engine and the car is quite a bit heavier.
yeah....i deliver pizza in style
