Several factors influence actual fuel economy, including:
* Driving style: Aggressive acceleration and braking will dramatically reduce fuel economy.
* Vehicle condition: Proper tire inflation, regular maintenance, and a clean air filter all contribute to better fuel efficiency.
* Terrain: Hilly or mountainous terrain will lower MPG compared to flat areas.
* Load: Carrying heavy cargo will reduce fuel economy.
Expect to pay more at the pump compared to vehicles with smaller, more fuel-efficient engines. If fuel economy is a high priority, the 2010 Grand Caravan isn't the best choice.
