* Smaller engines (like the inline-6): Might achieve closer to the higher end of that range, potentially even a little better under ideal conditions.
* Larger V8s: Would likely get closer to the lower end or even worse, especially with spirited driving.
Several factors influence the actual MPG:
* Engine size: The bigger the engine, the lower the fuel economy.
* Transmission: Automatic transmissions generally get slightly worse fuel economy than manuals.
* Driving style: Aggressive acceleration and high speeds significantly reduce MPG.
* Vehicle condition: Proper tune-up and maintenance can improve fuel economy.
* Tire pressure: Underinflated tires reduce gas mileage.
Therefore, 8-15 MPG is a broad estimate. It's impossible to give a precise number without knowing the specific engine and driving conditions.
