Unlike other car fuel economy surveys, TrueDelta's Gas Mileage Survey includes questions about how and where a car was driven. So you can get an idea of the Pontiac G8's real-world gas mileage (MPG in US and UK, L/100km elsewhere) based on how and where you drive a car.
- view all responses; guests view a maximum of five MPG (or L/100km) gas mileage responses per Pontiac G8 powertrain
- filter gas mileage results based on driving style and driving conditions

About TrueDelta's Pontiac G8 Gas Mileage Survey
Government estimates often aren't indicative of actual, real-world gas mileage for the Pontiac G8.
Here, unlike anywhere else, you can learn what actual fuel economy and gas mileage (MPG) to expect from the Pontiac G8 based on how you drive and the roads you typically drive on. TrueDelta's Gas Mileage Survey (formerly the Fuel Economy Survey) is the only one to ask Pontiac G8 owners about driving style, terrain, A/C use, driving speed, and other factors that can affect the Pontiac G8's fuel economy and gas mileage in the real world.
And, members can now filter real-world Pontiac G8 gas mileage results by the most important factors.
