I decided to do a fair comparsion of Aussie petrol vs US petrol prices using the Holden Commodore SS and the Pontiac G8-GT (The rebadged version we get here)
The petrol tank is: on US G8 GT: 19 gallons
Petrol tank on Commodore SS: 73 litres
Cost to fill Pontiac G8 tank @ $1.59 USD/gallon: $30.21 USD
Cost to fill Commodore SS tank @ $1.05 AUD/litre: $76.65 AUD
Makes me think Im lucky I get your Aussie knowhow on the cheap if I want to buy a Pontiac G8
More fun with the 6.0 LS6 and 4 doors to boot.
