Latest fuel price predictions point to a petrol and diesel price cut this September

We’re already well into August at this point, meaning that the Department of Mineral Resources and Energy’s (DMRE) fuel price adjustments are fast approaching. After what turned out to be a pretty rough couple of months for SA’s diesel drivers, the Central Energy Fund (CEF) has some good news for fuel prices this September.

The latest predictive snapshot (captured 12 August) reckons that all South African motorists are due a fuel price cut at the pumps when September eventually rolls around. The DMRE typically adjusts fuel prices on the first Wednesday of the new month, which will fall on 3 September next month.

Fuel for the soul

Of course, a lot can change between now and then. We should note that the CEF’s predictive figures found below are not set in stone and are subject to change. These do, however, offer the most accurate insight into South Africa’s ever-changing fuel price economy. The CEF keeps track of those economic factors that influence the price of fuel locally — namely, the Rand/US Dollar exchange rate and international oil prices.

Diesel supplies have steadily risen in recent weeks, leading to cheaper prices according to Bloomberg, although it notes this may not remain the case forever, as a looming winter in the Northern hemisphere could alter things a bit. But that’s a problem for another month. For now, though, we’re revelling in the cheaper prices locally.

The Rand is currently weaker than it was throughout June and July, contributing to even smaller expected price decreases. If the Rand can manage to strengthen throughout August, we could see even larger price decreases by the time September rolls around.

Here are the petrol and diesel price predictions (so far) for September 2025:
