September 2026 pump prices
The interactive fill-up cost calculator has moved to the current fuel prices page, where it runs on this month's prices.
Brent crude surged from an average of $87.89 to around $101 a barrel on continued Middle East conflict and reduced Russian output, overwhelming everything else — the rand barely moved and the slate levy rose only 4.38c/l. Inland 95 petrol broke R30/litre for the first time. See the current month →
What changed in September 2026
September 2026 hit every grade at once. Petrol 93 and 95 both rose R1.34/l, diesel jumped R2.94/l (500ppm) and R3.15/l (50ppm), illuminating paraffin rose R2.13/l wholesale, and even LP gas — August's one bright spot — increased 69c/kg nationally (79c/kg in the Western Cape).
The driver was renewed Middle East risk. Brent crude rose from an average of $82.37 to $87.88 a barrel over the review period, on continued US-Iran tension and uncertainty over oil flow through the Strait of Hormuz, plus higher shipping costs. A stronger rand partly offset this — it appreciated from R16.46 to R16.21 to the dollar, cutting the Basic Fuel Price contribution by 21.07c/l on petrol, 29.06c/l on diesel and 26.69c/l on paraffin — but not by enough to prevent the increase.
Two levy-side changes added further pressure. The slate levy rose 21.90c/l, from 61.38c/l to 83.28c/l, following a negative cumulative slate balance of R9.519 billion at the end of July — the opposite of August's levy cut, and a sign there's now much less room in that mechanism to absorb the next shock. Separately, the Minister approved a 4.9c/l increase in the retail price structure (from 315.1c/l to 320.0c/l) specifically to accommodate a wage increase for service station staff — pump attendants, cashiers and admin personnel.
Diesel remains the more exposed grade, consistent with the pattern since July: shipping and refining risk around the Middle East hits distillate fuels harder than petrol.
Inland, a 60-litre tank of petrol 95 cost R1,615.20 in September — about R80.40 more than August. A 70-litre diesel tank (typical Hilux or Fortuner) cost roughly R2,037.70 at the wholesale reference price — about R205.80 more than August. At the coast a 60-litre tank of 95 cost R1,563.00.
How SA fuel prices are set
South Africa uses a regulated fuel pricing system. Prices are set by the Department of Mineral and Petroleum Resources (DMPR), announced in the last week of each month, and take effect on the first Wednesday of the following month.
The calculation combines three components: the Basic Fuel Price (BFP), which reflects the international import cost of refined fuel plus shipping; government levies (general fuel levy, Road Accident Fund levy, customs and excise); and the slate levy, which recovers historical under-recoveries across the industry.
Petrol 93 is the standard grade for most of SA. Petrol 95 is required on the coast (Western Cape, KwaZulu-Natal) because higher altitude inland areas require a lower-octane fuel at the same combustion ratio. The coast requires 95. Most inland vehicles run perfectly on 93. Never put 93 in a turbocharged or high-compression engine that specifies 95.
The slate levy explained
The slate levy is unique to SA's pricing structure. It exists because the regulated price can fall below the actual import cost of fuel, creating a "negative slate" — effectively a debt owed to fuel importers. The slate levy is a mechanism to recover that debt gradually, and it self-adjusts as the balance improves — or worsens.
This is exactly what caught up with motorists in September. Having been cut to 61.38c/l in August as the balance improved, the cumulative slate balance swung negative again — to R9.519 billion at the end of July — and the Self-Adjusting Slate Levy Mechanism pushed the levy back up to 83.28c/l, a 21.90c/l increase. Unlike August, when the levy cushioned the pump price, in September it added to the pain.
August's piece on this page flagged that a 61.38c/l slate levy left "far less headroom" if crude spiked again. That's exactly what happened: crude rose, the levy rose with it instead of absorbing the shock, and petrol and diesel both moved up together in September for the first time since this run of increases and cuts began. The same pattern held into October, when crude — not the levy — did almost all the damage.

How fuel costs affect your car purchase decision
Running costs are one of the most underestimated factors in the total cost of ownership calculation for South African car buyers. At September 2026 prices, the difference between a 7L/100km petrol hatchback and a 10L/100km V6 SUV was roughly R500–R800 per month in fuel alone, depending on monthly kilometres driven.
When evaluating a used car purchase, factor in:
- Average fuel consumption (L/100km) from manufacturer specs — add 10–15% for real-world SA driving
- Petrol vs diesel: diesel was more expensive per litre than petrol inland in September, and diesel engines also cost more to maintain and repair — the old "diesel saves you money" assumption did not hold at September 2026 prices unless you cover very high mileage
- Tank size: a larger tank means fewer fill-ups but higher cash outlay per fill
- Turbocharged engines: most require 95 octane, which was R0.16/l more expensive than 93 inland (R0.08/l at the coast) in September
- Monthly kilometre estimate × L/100km ÷ 100 × current price = monthly fuel budget
Monthly km ÷ 100 × consumption (L/100km) × fuel price per litre = monthly fuel cost. Example at September 2026 prices: 1,500 km/month ÷ 100 × 8.5 L/100km × R26.76 (inland 93) = R3,412/month in fuel. Run the same sum with this month's price for a current figure.
Everything rose together for the first time this cycle
Petrol and diesel moved in the same direction for the first time since June — both up, with diesel again taking the bigger hit at over R3/l on the 50ppm grade. A stronger rand helped, but not enough to offset renewed Middle East risk and a slate levy that moved from cushioning the price to adding to it. That pattern didn't stop — October brought the biggest jump of the year, this time driven almost entirely by crude oil rather than the levy.
Where to find current prices
South Africa's fuel price cycle follows a fixed pattern: the DMPR publishes the official adjustment in the last week of each month, with the new price taking effect on the first Wednesday of the following month. The September 2026 prices on this page were superseded on Wednesday 7 October 2026.
