Does gas mileage depend on how you drive?
Reality: Fuel efficiency doesn’t really start to drop until you reach speeds higher than 60. And how smoothly you drive makes much more of a difference on gas mileage than how fast. According to the U.S. Department of Energy (DOE), most cars’ fuel efficiency peaks at speeds from 35 to 60 miles per hour.
Does going 80 mph use more gas?
If your car has an on-board computer that displays your instant gas mileage, the difference between 60 mph and 80 mph will be obvious—and substantial. At 60, a typical four-cylinder car might average about 30 mpg; at 80, it could fall to about 20 mpg.
How does fuel economy work?
Fuel economy refers to the number of miles a car can travel using a specific amount of fuel. It’s measured in miles per gallon or miles per gallon gasoline equivalent (or MPGe) for electric vehicles. The more miles per gallon a car gets, the farther it can go on a tank of gas and the better its fuel economy.
How can I drive less fuel?
13 Tips to Reduce Fuel Consumption
- Drive only when needed.
- Make sure the gas cap is on tight.
- Avoid idling.
- Accelerate and break steadily.
- Drive the speed limit.
- Coast when possible.
- Use cruise control on the highways.
- Make your car more aerodynamic.
What is the best speed to drive for fuel economy?
55-65mph
7. The Energy Saving Trust says that the most efficient speed you can travel in a car in terms of achieving the best fuel economy is 55-65mph. Any faster, though, and the fuel efficiency decreases rapidly. For example, driving at 85mph uses 40\% more fuel than at 70mph (oh, and it’s illegal too).
