Be consistent. Unintentional dips in speed and sudden bursts of acceleration to keep pace take a toll on your tank—and your wallet. In fact, tests have shown that varing your speed up and down between 75 km/h and 85 km/h every 18 seconds can increase your fuel use by 20 percent.
Consider using cruise control for highway driving. Be mindful, however, that little variations in speed can actually be good when gravity does the work. Where traffic patterns permit, allow your speed to drop when you travel uphill, then regain your momentum as you roll downhill.

"Are you a driver? Did you know for every litre of gasoline used your vehicle produces 2.3 kg of CO2 emissions? This may be shocking but adopting a few fuel-efficient driving techniques such as maintaining a steady speed will not only help you reduce your carbon footprint but will also save you money on your gas bills."

"With the busy lifestyle most of us lead, driving is often about getting to our destination as quickly as possible. We often react to traffic and drive at varying speeds. However maintaining a steady speed will optimize your fuel savings and reduce the carbon emissions from your vehicle."

"A test was conducted with three drivers using the same vehicle. They drove an equal distance and maintained an average speed of 80 km per hour.
The driver in the green car maintained a steady speed throughout the trip. The driver of the blue car changed speeds every 18 seconds. And the driver of the red car changed speeds every 12 seconds.
At the end of the trips the blue car used 20 per cent more fuel and the red car used 48 per cent more fuel than the green car that maintained the same speed throughout the trip. As you can see, frequently varying your driving speed leads to a higher consumption of fuel and can dig a big hole in your pocket when it comes to gas bills."

"To maintain a steady speed, consider using cruise control for highway driving.
And for experienced drivers, this technique can go beyond cruise control. In fact on hilly terrain and wherever traffic permits, you will consume less fuel by allowing your speed to drop when you travel uphill and building momentum when driving downhill. Experienced drivers can try this technique on hilly terrain and where traffic conditions permit."

"The next time you’re on the road consider maintaining a steady speed throughout the trip to reduce emissions from your vehicle and reduce your gas bill while you’re at it."
