Also asked, what is the most fuel efficient speed?
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).

Moreover, does speed affect gas mileage?
Speed Kills MPG Your car's gas mileage decreases once it gets past its optimal speed. For most cars, this is around 55-60 mph. This means that every time you go over this speed, you're essentially wasting gas and money - and creating unnecessary greenhouse gases.
The 50 Best Cars & SUVs With Great Fuel Economy Despite the advancement in hybrid technologies and modern fuel saving systems, most cars still have low gas mileage. The average is still around 23 mpg in the city. Even worse, average gas mileage is in the teens for most SUVs and minivans.
