Yes. Significantly. Almost any vehicle will get it's best gas mileage at a steady 55 MPH. Above that you use extra fuel to maintain momentum and overcome increasing drag on your car from wind. My truck at 55 mph gets about 26 miles per gallon. At a steady 70 mph it gets just over 19.
-------------------
Within reason yes.
However, if your are going down hill with no throttle (In modern cars/trucks) you are using zero fuel and it won't matter what speed you are doing.
On the flat, every mph more will use more fuel.
There is an exception, it depends on what gear you are in. If you are in a lower gear then you will use more fuel than a higher gear.
For the best efficient fuel usage, get into the highest gear for your car and the terrain, keep the revs steady and use the terrain (coast in gear on downhill stretches) and look ahead. See the usage and terrain, step off the fuel in advance instead of using the brakes and slowly decelerate.
My diesel VW Golf gets over 70mpg at 55mph with that philosophy!
What else can I help you with?
If it takes an hour to drive 80 miles and an hour to drive 50 miles do you save on fuel?
If it take you an hour to drive 80 miles and an hour to drive 50 miles, you will not necessarily save fuel. Fuel consumption is measured by miles per gallon, not time driving. You use less fuel driving 50 miles than 80 miles.
How do you calculate fuel consumption per Kilowatt hour in diesel engine?
You can calculate fuel consumption per Kilowatt hour in diesel engine by multiplying the miles per gallon by the wattage per hour that the engine runs. This gives the net Kilowatt hour fuel consumption.
What is the best highway driving speed to conserve fuel?
55 miles per hour.
At what speed do you get the best fuel effeciency?
if drive at 55.6 miles a hour you will get best mileage.
How many miles can a plane fly without refueling?
An airplane's range is determined by it's groundspeed, fuel burn rate, and fuel capacity. If an airplane burns 10 gallons of fuel per hour and has a ground speed of 200 miles per hour, with a 40 gallon fuel tank. It could fly about 800 miles. You have to keep some fuel in reserve. At least 30 minutes of fuel for daytime, and 45 minutes at night.
How far can a plane fly if it flies at a rate of 170 miles per hour for 4 hours with unlimited fuel?
4 x 170 miles = 680 miles
What is 250 mpg in kph?
Miles per gallon can't be converted to kilometers per hour. Miles per gallon measure fuel economy, while kilometers per hour measure speed.
What could cause a 2003 VW Polo with 1.6 liter diesel to stall out and die at 75 miles per hour?
Dirty fuel filter.Water in fuel.
How many miles per hour can a Saturn go until the gas run out?
speed has nothing to do with fuel capacity
Why does your car quit after driving 3 miles and wont start again for an hour or so?
I'm guessing it is fuel related, you may have a plugged up fuel filter or a faulty fuel pump.
First route will take 1 hour and it is 80 miles away the other route also takes an hour but is only 50 miles away Which of these will be the best way to go to save on fuel?
The first route will be the best option since the distance of 80 miles is bigger than 50 one hence the fuel consumption is used well.
What is the effect on force if the velocity changes from 5 mph to 10 miles per hour?
Velocity does not affect force.
