5 Eco-driving tips to save fuel

Did you know that your driving technique — not just driving distance and time — affects how much fuel your vehicle uses? Eco-driving makes it possible to save hundreds of dollars per vehicle each year on fuel, and makes up an important part of a fleet sustainability program.

What is eco-driving?

Eco-driving is a method of driving a vehicle with the goal of using less fuel and having less of an impact on the environment.

The first use of the term “eco-driving” is attributed to the Swedish National Driving School in 1998. The concept then appeared in some European driving programs in the early 2000s, and has since gone global.

What can be achieved by eco-driving?

According to the U.S. Department of Energy, aggressive driving can reduce your petrol mileage by 15-30% (at highway speeds) or 10-40% (in stop-and-go traffic.) As fuel consumption legislation becomes tighter, it is worth adopting eco-driving techniques to improve your fleet’s carbon footprint.

Benefits of eco-driving as cited by the U.S. Forest Service:

• Lower fuel use and costs
• Reduce exhaust emissions, including CO2
• Reduce vehicle wear
• Increase safety

Eco-driving techniques

1. Don’t slam on the brakes

Avoid speeding up and slowing down too quickly whenever possible. Instead, traffic permitting, take your foot off of the accelerator and coast to slow down.

Sudden acceleration and braking increases fuel consumption and can wear down your vehicle. Slamming on the brakes can cause the brake pads to overheat and wear down more quickly, and cause the rotors to warp.

Harsh braking can also trigger your vehicle’s anti-lock braking system (ABS) when it’s not needed, which could worsen brake performance. If you have an older vehicle model without ABS, harsh braking can cause a “flat-spot,” an uneven patch of wear, to appear on your tires.

2. Regulate your speed

According to Natural Resources Canada, if you change your speed back and forth from 75 km/h to 85 km/h every 18 seconds, you risk increasing fuel usage by a whopping 20%.

For as long as you can do it safely, in light of traffic conditions, try to maintain a steady speed and consider using cruise control. Letting your speed drop slightly as you ascend a hill can also be beneficial; you will regain some speed on the other side.

3. Reduce excess weight

The heavier your vehicle, the more fuel is needed to move it. In recent years, automakers have improved materials and designs in order to reduce vehicle weight, but carrying heavy items and equipment can still have a negative effect on fuel consumption.

Check if there are pieces of equipment that can be removed from the inside or top of your vehicle, that you do not need for any tasks that day. When purchasing a new vehicle, consider choosing a smaller-engine vehicle, fuel efficient model that suits your fleet needs or even an electric vehicle.

4. Optimise routes

Try combining multiple trips in one and plan your route ahead of time. Stay tuned to traffic reports, note construction areas, and avoid routes that cut through busy intersections or cities if possible.

Through route optimisation, you can minimise idling, reduce the risk of harsh braking, and shorten time spent driving. If you’re dealing with a fleet of vehicles, consider using technology tools that assist with dispatch and routing to coordinate your resources.

5. Avoid idling

Did you know that letting your vehicle idle for more than 10 seconds uses up more fuel than if you had turned your vehicle off and then on again? Argonne National Laboratory has stated that each day an estimated 1 million long-haul trucks idle during mandated rest stops. Following Australia's NHVR's fatigue-management rest requirement rules would see hours of idling if ignition was not turned off.

When you are not on the roads, turn off your vehicle if you expect to be idling for more than 60 seconds.
