Record territory, with three weeks still to run
The petrol price October 2026 adjustment takes effect on Wednesday 7 October, and early Central Energy Fund data points to another sharp increase that would take both petrol and diesel to record levels.
Treat the numbers below as a direction, not a price. The CEF snapshot is a daily running average across the review period, and it moves every day until the month closes. Nine days of data is not a forecast.
There is also no single figure circulating. Different snapshots taken on different days in the first week of September produced materially different numbers, and they are all being reported as the October outlook.
The figures being reported, and how they differ
| Snapshot date | Petrol 93 | Petrol 95 | Diesel 0,05% | Diesel 0,005% |
|---|---|---|---|---|
| Around 2 September | Under-recovery R2,11 | R2,22 | R2,83 | R3,11 |
| Around 7 September | R1,87 | R1,99 | R2,16 | R2,41 |
| First seven days of September | R1,81 | R1,93 | R1,73 | R2,03 |
| Reported 9 September | About R1,88 | About R2,00 | About R1,50 for 500ppm | About R1,80 for 50ppm |
An under-recovery is the amount by which the local price would have to rise to match what importing the fuel actually costs, at current oil prices and the current rand.
The spread across these snapshots is roughly 30 cents on petrol and more than a rand on diesel. That is not an error in any of them. It is the daily average shifting as oil and the rand move. Anyone quoting a single confident October price this early is overstating what the data supports.
What that would mean at the pump
Projections published this week put 95 unleaded at around R28,05 at the coast and about R28,92 in Gauteng if current conditions hold. The June 2026 records were about R27,19 at the coast and R28,05 inland, set during the Iran War shock, which itself broke the July 2022 record of R26,74.
Diesel 50ppm is projected at about R30,29 at the coast and R31,85 inland, against all-time highs of about R30,62 and R31,38 recorded earlier this year. Some reporting puts the diesel outcome higher, above R32.
Illuminating paraffin is also in under-recovery, which matters for households that cook and heat with it and do not own a car at all.
Why it is happening
Two conflicts are driving this, and neither is easing.
The Middle East war has kept pressure on the Strait of Hormuz, the passage through which a large share of seaborne oil moves. Brent crude pushed above $99 a barrel this week, its highest in nearly seven weeks, after reported strikes on vessels in the Gulf. Peace talks that briefly calmed markets in July collapsed.
Separately, Ukrainian strikes on Russian refining capacity have tightened the diesel market specifically. That is why diesel under-recoveries have consistently run ahead of petrol in recent months.
The rand is doing some work in the other direction, trading around R15,99 to the dollar on 9 September, but not enough to offset the oil move.
What already happened in September
The Department of Mineral and Petroleum Resources confirmed increases from Wednesday 2 September 2026 of R1,34 a litre for both grades of petrol, R2,93 for 0,05% sulphur diesel and R3,14 for 0,005% sulphur diesel. Our coverage of the September fuel increase has the detail.
So an October increase of the scale being projected would land on top of a September increase that was itself the largest diesel move of the year. For a logistics operator running 50ppm diesel, that is close to R5 a litre added in two months.
What this does to everything else
Fuel feeds through to food, transport and services with a lag of weeks. Inflation had been running at 4,3% in July, and the second quarter GDP figure was a contraction of 0,2%, so the timing is poor. Higher fuel prices push inflation up while squeezing the spending that would otherwise support growth, which is a combination the Reserve Bank has flagged before. Our tracking of inflation this year sets out where the numbers were before this shock.
The pricing mechanism itself is under review, and the fuel pricing model review is the process that could change how these monthly adjustments are calculated.
What to do before 7 October
- Fill up before the adjustment if the final announcement confirms an increase. The official figures come from the Department of Mineral and Petroleum Resources in the last days of September.
- Do not act on a mid-month projection as if it were the price. The last week of the review period often moves the number.
- If you run a diesel fleet, the gap between 500ppm and 50ppm matters more than usual right now, because the projections for the two grades diverge.
- Coastal and inland prices differ by roughly 90 cents. Check the figure for your zone, not the national headline.
Where to check
The Central Energy Fund publishes the daily fuel price snapshot, and the Department of Mineral and Petroleum Resources publishes the official monthly adjustment before it takes effect. The DMPR announcement is the only figure that is final. Anything published before that, including the table above, is an indication based on incomplete data.
