Cars with manual transmissions get noticeably better gas mileage than those with automatic ones — about 2-5 mpg (about o.80-2.0 kpl) better, in fact. This is because the driver has more control over the shifting in a car that has a manual transmission, but with an automatic transmission, the car waits until the driver starts pushing down on the gas or the car hits a preset point of speed or rotations per minute.
Other facts about gas mileage:
- The United States consumes almost 19 million barrels of oil per day but produces only about 7 million.

- The cheapest gas in the world is found in Venezuela, where gas can be found for about 6 US cents a gallon (about four liters).
