With fuel prices continuing to fluctuate in South Africa, finding practical ways to save on fuel when driving has become essential for every motorist. And just like comparing car insurance to cut monthly costs, small changes to your driving habits can result in big savings at the pump.

 

Does Speeding Consume More Fuel?

Yes, speeding significantly increases your fuel consumption. The faster you drive, the harder your engine has to work, and that extra effort burns more fuel. For example, driving at 120 km/h instead of 100 km/h can increase fuel consumption by up to 20%, depending on your vehicle.

 

What Is the Best Speed to Save Fuel?

The optimal fuel-saving speed varies depending on the vehicle, but most cars are at their most efficient between 60 to 90 km/h.

Here’s a helpful illustration of how speed affects fuel consumption:

Speed (km/h) Fuel Efficiency (l/100km)
60 km/h 6,0
80 km/h 6,5
100 km/h 7,5
120 km/h 9,0
140 km/h 11,5

(Values are general estimates and may vary by vehicle type.)

 

7 Smart Driving Techniques That Help Save Fuel

  1. Maintain Steady Speeds: Fluctuating between fast and slow speeds forces your engine to work harder.
  2. Avoid Harsh Acceleration: Putting pedal to the metal can increase fuel consumption by up to 40% in stop-start traffic.
  3. Use Cruise Control Wisely: Cruise control can help maintain a consistent speed on flat roads. But driving uphill keeps your car in a lower gear for longer, using more fuel.
  4. Anticipate Stops: Instead of braking hard at the last second, ease off the accelerator early.
  5. Keep Tyres Inflated: Underinflated tyres increase rolling resistance, meaning your engine has to work harder to move the car. Check tyre pressure at least once a month.
  6. Limit Idling: Letting your engine idle for more than 30 seconds uses more fuel than turning it off and restarting it.
  7. Lighten Your Load: Excess weight puts extra strain on your engine. Remove unnecessary items from your boot, and remove roof racks when not in use.
