Early-month tracking from South African fuel-price trackers points to a third consecutive month of increases for the October 2026 adjustment — and this time petrol isn't getting off lightly. Where July, August and September each had one grade doing most of the damage while the other held relatively steady, October's early numbers show petrol and diesel rising together, both driven by the same underlying story: crude oil, not the rand or the slate levy, is now the dominant factor.
What the early projections show
Based on tracking data published through early September, here's how the projected increase compares against the confirmed September inland prices:
| Fuel Type | September Price | Projected Change | Projected October Price |
|---|---|---|---|
| Petrol 93 | R26.76/l | +R1.87/l | ~R28.63/l |
| Petrol 95 | R26.92/l | +R1.99/l | ~R28.91/l |
| Diesel 0.05% / 500ppm | R29.11/l | +R2.16/l | ~R31.27/l |
| Diesel 0.005% / 50ppm | R30.05/l | +R2.41/l | ~R32.46/l |
Why petrol is catching up to diesel this time
Brent crude has climbed to around $97 a barrel as of early September — up more than 10% over the past month and nearly 50% higher than a year ago. Two things are driving it: the Middle East conflict remains unresolved, and Russian oil output has dropped following Ukrainian strikes on export infrastructure. Both of these hit the international price of refined product broadly, not just one grade, which is why petrol is now moving almost as much as diesel — a change from the pattern since July, where diesel absorbed most of the damage while petrol was cushioned by levy adjustments.
The rand isn't providing much relief either. Unlike September, when a stronger rand measurably softened the blow, early September trading has been choppy — the rand weakened toward R16.14/$ on soft manufacturing PMI data, then recovered somewhat as the dollar itself lost ground. There's no clear trend yet, and nothing suggesting the rand will do for October what it partly did for September.
What this means for you
For a 50-litre tank of Petrol 95, the projected October increase works out to roughly R99.50 more per fill-up than September. Diesel drivers are looking at an even bigger jump — around R150-R170 more per tank depending on grade. Combined with September's increase, that's two consecutive months of real budget pressure, particularly for diesel bakkie owners and anyone running a delivery fleet.
How the projections compared to the confirmed outcome
The official DMPR adjustment, effective 7 October 2026, came in higher than these early-month projections on every grade — October was worse for motorists than the numbers above suggested, driven almost entirely by crude oil overshooting expectations.
| Fuel Type | Projected (7 Sept) | Confirmed (7 Oct) | Difference |
|---|---|---|---|
| Petrol 93 | +R1.87/l | +R3.12/l | R1.25/l worse than projected |
| Petrol 95 | +R1.99/l | +R3.33/l | R1.34/l worse than projected |
| Diesel 0.05% / 500ppm | +R2.16/l | +R2.84/l | R0.68/l worse than projected |
| Diesel 0.005% / 50ppm | +R2.41/l | +R3.24/l | R0.83/l worse than projected |
Brent crude rose from an average of $87.89 to around $101 a barrel over the review period — well beyond the ~$97 these projections were based on — on continued Middle East conflict and reduced Russian output following strikes on export infrastructure. The rand provided no cushion either: it was essentially flat over the period, unlike September when a stronger rand partly offset the increase. The slate levy rose only 4.38c/l (83.28c/l to 87.66c/l), a minor factor next to crude. Inland 95 petrol broke R30/litre for the first time ever as a result.

Track record: how reliable are these early projections?
Not perfectly, and not in the same direction each time. July's early projections understated the relief motorists eventually got. September's early projections understated the pain — the confirmed increase came in worse than projected on every grade once the slate levy moved against consumers. October followed the same pattern as September — worse than projected on every grade — but this time crude oil itself, not the slate levy, was the reason the early numbers fell short. Three of the last four months have now undershot the real increase; treat these numbers as a planning signal for the size and direction of the move, not a locked-in price, until the DMPR confirms.
