* Engine size: The Silverado came with various engine options (V6, V8, etc.) Larger engines consume more fuel.
* Transmission: Automatic or manual transmissions affect fuel economy.
* Driving style: Aggressive acceleration and braking significantly reduce fuel efficiency.
* Vehicle condition: Proper tire inflation, regular maintenance, and overall vehicle condition impact fuel economy.
* Terrain and weather: Driving uphill, in heavy traffic, or in extreme weather conditions reduces fuel economy.
To find the approximate fuel consumption for a *specific* 2007 Chevy Silverado, you would need to look up the EPA estimated fuel economy for that particular model's engine and transmission combination. This information might be found in the owner's manual or on websites like fueleconomy.gov (for US vehicles). Even then, this is an *estimate*; real-world mileage will vary.
