Fuel Prices Are Hitting Hard. Here’s How to Get More From Every Tank

Fuel prices have become one of those monthly expenses that motorists watch closely. In September 2026, South African drivers faced another significant increase, with both grades of petrol rising by R1.29 per litre, while diesel increased by R2.939 to R3.149 per litre, depending on the grade. The official Department of Mineral and Petroleum Resources (DMPR) adjustment took effect on 2 September.

For many South Africans, that means every trip, school run, commute and weekend drive costs a little more.

While we can't control what happens to international oil prices, the rand or the monthly fuel adjustment, there are ways to make sure your vehicle is using fuel as efficiently as possible.

Start with the basics: look after your car

A vehicle that isn't running properly can use more fuel than it should.

The Automobile Association of South Africa notes that regular servicing, correct tyre pressure and proper wheel alignment can all make a difference to fuel consumption. It estimates that a well-maintained vehicle can use 10–20% less fuel than one that is improperly maintained.

That makes regular maintenance about more than simply preventing breakdowns. It can also help you get more kilometres out of every litre.

Check your tyre pressures

Your tyres have a direct effect on how efficiently your vehicle moves.

Under-inflated tyres increase rolling resistance, meaning the engine has to work harder to move the vehicle. The AA also notes that incorrect tyre pressures can increase tyre wear and affect handling.

Check your vehicle manufacturer's recommended pressures rather than simply using a number you've heard elsewhere. You'll usually find the correct specifications in the owner's manual or on a sticker on the vehicle.

Take it easy on the accelerator

Aggressive acceleration and unnecessary high engine speeds can increase fuel consumption.

The AA recommends accelerating gradually and avoiding harsh driving. Maintaining a safe following distance can also help you avoid constantly accelerating and braking in traffic.

In other words, smooth driving isn't just easier on the passengers. It can also be easier on your fuel bill.

Don't carry what you don't need

That toolbox you've been carrying around for six months? The camping equipment you forgot to unpack? The roof box that's still fitted even though you're not using it?

Extra weight means your vehicle needs more energy to move. Roof racks and roof boxes can also increase aerodynamic drag.

The AA recommends removing unnecessary weight and roof equipment when it isn't needed.

A quick clean-out could therefore save you more than just boot space.

Avoid unnecessary idling

If you're sitting stationary for an extended period, your engine is still consuming fuel even though you're not going anywhere.

The AA recommends avoiding unnecessary idling and notes that an engine warms up more quickly while driving than while simply sitting stationary.

Of course, there are situations where keeping the vehicle running is necessary, so this isn't about switching your engine off every time you stop. It's simply worth avoiding unnecessary idling where practical and safe.

Don't ignore warning signs

Perhaps one of the biggest things you can do for fuel efficiency is pay attention to your vehicle.

Changes in fuel consumption, unusual noises, warning lights, rough running or a noticeable change in how the vehicle drives shouldn't simply be ignored.

A problem with the engine, tyres, brakes or other components can affect how efficiently your vehicle operates. Getting issues checked early may also help prevent a relatively small problem from becoming a much bigger repair.

Every kilometre counts

With fuel prices changing from month to month, there isn't much the average motorist can do about the price displayed at the pump.

But you can control how efficiently your vehicle uses what you put in the tank.

Keep up with servicing. Check your tyres. Drive smoothly. Remove unnecessary weight. Pay attention to warning signs.

And when something doesn't feel right, get it checked.

Because when fuel costs this much, you want every litre to take you as far as it can.
