Fuel is one of the heavy expenses that impacts any business. Costs of fuel fluctuate constantly, and it can be difficult to monitor consumption. One thing is for certain, speeding actually wastes fuel.
You may know excessive speeding can dramatically reduce fuel economy, but few of us have bothered to learn just how much it costs. Following is some useful and startling information compiled from DOE data.
The DOE calculation
Unfortunately, it’s true. Your vehicle’s gas mileage decreases once it gets past its optimal speed. For most vehicles, this is around 55 mph. This means that every time you go over this speed, you’re essentially wasting fuel and money. You’d be surprised to learn that a slight decrease in your highway driving speed could significantly reduce your fuel consumption, while only adding a few minutes to the travel time.
According to studies backed by the DOE, the average vehicle will be at its advertised peak efficiency MPG at 55 mph. But as the speed increases you lose up to 28% of efficiency when traveling at highway speeds!
– 3% less efficient at 60 mph
– 8% less efficient at 65 mph
– 17% less efficient at 70 mph
– 23% less efficient at 75 mph
– 28% less efficient at 80 mph
