1. Tame the speed demon

Not everyone is in sports cars, but even if you own one (like this green Audi TTRS), resist the temptation to speed.

The faster you drive, the more drag is created and the more fuel your car will use. Since speeding is also against the law, you may quickly find yourself receiving a fat ol' speeding ticket, which will reduce your holiday budget even more. Pay attention to the road signs and adhere to traffic regulations; they're there for your and other road users' protection.

2. Chill out and sail smoothly

Easy and relaxed is the attitude to have when driving on busy highways this December.

The more smoothly you drive, the less fuel you will use. Keep a proper following distance of at least 2 seconds between you and the vehicle in front. Don't speed like a maniac only to slam on the brakes at the next traffic light. In doing so, you're wasting all that expensive energy—in other words, fuel!

Staying relaxed and avoiding potential road rage incidents may potentially save your life, too.

3. Ditch the rooftop stacking

Increased wind resistance will be detrimental to your fuel consumption.

Avoid piling luggage and accessories on top of your car, as it creates drag and increases fuel consumption. Consider a trailer or hitch-mounted rack for bulky items.


4. Reduce the load

Travel light if you want to keep fuel costs as low as possible.

Don't pack everything but the kitchen sink. It's difficult when there are toys, bikes, and camping gear, but keep the load as light as you possibly can.

5. Don't let your car idle 

Switching off means saving fuel.

Don't let your car idle unnecessarily. If stuck in traffic or waiting for more than 30 seconds, switch off the engine. Restarting the car consumes less fuel than idling.

6. Windows up, AC down


Rolling down windows creates drag, increasing fuel consumption. Keep windows closed and utilise the air conditioner sparingly. Open windows only at low speeds when it's safe to do so.

7. Prioritise regular maintenance

Service and maintain your car regularly, and your wallet will thank you!

A well-maintained vehicle is a fuel-efficient vehicle. Schedule a pre-holiday checkup to ensure your car is in top condition.

8. Embrace cruise control

Cruise control maintains a constant speed, reducing fuel consumption, especially on long, flat stretches of road. However, avoid using it on hilly terrain, as it may lead to increased fuel usage. (These are SA's most fuel-efficient cars)


9. Strategize your fuel stops 

Filling up? Remember that 1 litre of petrol weighs 0.72 kg, so you don't have to overdo it.

Avoid filling up your tank to the brim if there are conveniently spaced service stations along your route. A full tank adds weight, increasing fuel consumption.

10. Ensure your car's tyres aren't underinflated

The harder your tyres, the less fuel you will use, but don't over-inflate either, as it can cause a loss of traction, which can result in an accident. Over-inflated tyres also wear out prematurely. Stick to the manufacturer's recommended pressure.

Here are the reasons a tyre won't inflate


Bonus tip: Plan your route!

Plan your route carefully to avoid unnecessary detours and traffic congestion. Consider using navigation apps that suggest fuel-efficient routes.
