There’s nothing worse than watching your fuel gauge drop faster than your spirits on a long overlanding trip. Whether you’re tackling the rugged trails of the Richtersveld or cruising through the vast expanses of the Kalahari, fuel efficiency is key to keeping your adventure on track.
At 4×4 Afrika, we know that every litre counts. That’s why we’ve put together these seven practical tips to help you squeeze every last kilometre out of your 4×4’s fuel tank. From driving smarter to making a few clever modifications, these tips will help you go further, explore more, and worry less about your next fuel stop.
1. Drive Smoothly and Efficiently
Your driving style has a massive impact on fuel consumption. Aggressive acceleration and hard braking can increase fuel consumption by up to 40%, so smooth, steady driving is the way to go. Stick to the speed limit—driving at 110 km/h instead of 120 km/h can save you up to 15% on fuel. On long, flat stretches, cruise control helps maintain a consistent speed, which is more fuel-efficient.
- Tip: Use apps like Tracks4Africa to plan your route and avoid unnecessary detours or rough terrains that can increase fuel consumption.
2. Lighten the Load
Every extra kilogram in your 4×4 costs you fuel. Do you really need that second spare tyre or the kitchen sink? Remove unnecessary items to lighten your load. Store heavy items low and centred to maintain balance and reduce drag. And if you’re not using your roof rack, take it off. Roof racks create wind resistance, which can increase fuel consumption by up to 20%.
- Tip: Invest in a Front Runner roof rack system, designed to be aerodynamic and modular, and only carry what you need.
3. Keep Your 4×4 in Top Shape
A well-maintained vehicle is a fuel-efficient vehicle. Clean air filters, spark plugs, and fuel injectors can make a big difference, so stick to your service schedule. Check your tyre pressure before every trip—under-inflated tyres increase rolling resistance, which burns more fuel. And don’t forget to use high-quality, low-viscosity engine oil to reduce friction and improve fuel efficiency.
- Tip: Regularly clean your fuel injectors with an injector cleaner, available at most local auto stores.
4. Choose the Right Tyres
Your tyres play a crucial role in fuel efficiency. All-terrain tyres offer a good balance between off-road capability and on-road fuel efficiency, so they’re a great choice for most overlanders. Stick to the manufacturer’s recommended tyre size—larger tyres may look tough, but they increase rolling resistance and reduce fuel efficiency. And don’t forget to rotate your tyres regularly to ensure even wear and maintain optimal fuel efficiency.
- Tip: Use a tyre pressure monitoring system (TPMS) like Steelmate, available locally, to keep an eye on your tyre pressure in real-time.
5. Reduce Aerodynamic Drag
4x4s aren’t exactly aerodynamic, but you can minimise drag with a few simple changes. Remove unnecessary accessories like roof racks when you’re not using them. If you’ve got a bakkie, a tonneau cover can reduce drag and improve fuel efficiency. And at highway speeds, close the windows—open windows create drag, so use the air conditioning instead.
- Tip: If you don’t have a canopy fitted use a tonneau cover designed to reduce drag and improve fuel efficiency on bakkies.
6. Consider Fuel-Efficient Modifications
A few smart modifications can help you save fuel. A snorkel can improve airflow to the engine, potentially boosting fuel efficiency. A high-performance exhaust system can reduce backpressure and improve fuel economy. And if you’re looking for a more advanced option, chip tuning can optimise your engine’s performance and fuel efficiency—just make sure it’s done by a professional.
- Tip: Install a raised air intake or snorkel, to improve airflow and fuel efficiency.
7. Plan Your Fuel Stops
In remote areas, fuel stations can be few and far between, so planning ahead is crucial. Invest in quality jerry cans or an auxiliary fuel tank to carry extra fuel—just make sure they’re securely mounted and comply with safety regulations. Plan your route to include reliable fuel stops, and use apps like Tracks4Africa to locate fuel stations in remote areas. And don’t forget to monitor your fuel consumption to avoid running out in the middle of nowhere.
- Tip: Install a long range fuel tank, there are plenty options available out there for your vehicle.
Final Thoughts
Increasing your 4×4’s fuel range doesn’t have to be complicated. With a few simple changes to your driving habits, maintenance routine, and vehicle setup, you can go further, explore more, and make the most of your overlanding adventures.
At 4×4 Afrika, we believe that every drop of fuel saved is a step towards more sustainable and enjoyable exploration. So, the next time you hit the trail, remember these tips and drive with confidence—knowing you’re getting the most out of every kilometre.
