Official figures — September 2026. These are the confirmed prices published by the Department of Mineral and Petroleum Resources (DMPR), effective Wednesday, 2 September 2026. Petrol 93 and 95 both rose 134 c/l, diesel 500ppm rose 294 c/l, diesel 50ppm rose 315 c/l and illuminating paraffin rose 213 c/l. The previous official prices took effect on 5 August 2026.
For South African motorists, fleet owners, and businesses, keeping track of fuel costs is essential for monthly budgeting. Because South Africa relies on a regulated pricing model, fuel costs do not fluctuate at the pump day by day. Instead, they change on a predictable, controlled schedule.
If you are wondering exactly when does petrol price change in South Africa, the short answer is: on the first Wednesday of every single month.
When Does Petrol Price Change in South Africa: current price
The official retail prices for petrol and wholesale prices for diesel are adjusted at midnight going into the first Wednesday of the month. The announcements are typically made a few days prior (usually on the preceding Monday or Tuesday) by the Department of Mineral and Petroleum Resources (DMPR).
Current Official Status:
- Next Effective Date: Wednesday, 2 September 2026
- Official Price Adjustment status: Pending DMPR Official Announcement (Currently tracking daily CEF indicator projections).
Please note that daily snapshots provided by the Central Energy Fund (CEF) are purely speculative indicator data based on ongoing market recoveries. Do not mistake mid-month forecasts for verified changes. Official figures are only locked in once published by the government.
Understanding the Monthly Cycle
The reason the price shifts specifically on this day comes down to the monthly pricing framework administered by the government. Rather than forcing retailers and consumers to deal with volatile, daily oil market swings, the Central Energy Fund (CEF) calculates a rolling average of international fuel costs and the Rand/US Dollar exchange rate over a set review period. This average is then applied as a single fixed adjustment for the following month.
What Day Does Petrol Price Change?
If you are trying to time your trip to the filling station, always look at the calendar for what day does petrol price change—it is consistently a Wednesday. If a massive hike is confirmed on the Monday before, queues at pumps nationwide typically peak on Tuesday evening just hours before midnight. Conversely, if a substantial price cut is implemented, waiting until Wednesday morning to fill up will save you money.

Price change from the previous month
Evaluating how the current cost compares to the prior month helps drivers identify broader economic trends. For the September 2026 cycle, consumers saw massive relief despite the final expiration of the temporary fuel levy relief framework:
- Petrol 95 Movement: Increased by 134 c/l (R1.07) from June
- Petrol 93 Movement: Increased by 134 c/l (R0.96) from June
- Diesel 50ppm Movement: Increased by 315 c/l (R2.92) from June
Real-World Examples
When international Brent Crude prices climb or the Rand weakens significantly against the greenback, the Basic Fuel Price (BFP) incurs an “under-recovery. This under-recovery translates directly into a price increase at the next monthly cycle. On the flip side, strong exchange rates and lower international refined product costs yield an “over-recovery,” bringing relief at the pumps on the first Wednesday of the month, as seen during the July drop.
Inland vs coastal prices
You will notice that fuel prices are always separated into two main geographic profiles: inland and coastal zones.
The Transport Cost Factor
The primary reason inland motorists pay more per litre than those at the coast comes down to transport and logistics. Since refined petroleum products arrive via sea at South African ports (like Durban), moving that fuel hundreds of kilometres inland to Gauteng or the Free State requires pipelines and rail infrastructure. The costs of operating these transport mechanisms are factored into the final magisterial district pricing zones.
Zone-Specific Adjustments
South Africa is divided into dozens of Magisterial District Zones (MDZs). While the fundamental Basic Fuel Price remains identical nationwide, local delivery costs alter the final regulated retail price slightly depending on exactly how far your local municipality sits from the closest major port or pipeline supply hub.
Petrol grades, diesel and related fuels
It is crucial to differentiate how different types of fuel are regulated in South Africa, as the rules governing petrol do not perfectly mirror those for diesel.
93 Octane vs 95 Octane Petrol
Unleaded petrol is strictly price-regulated at the retail pump. Stations cannot compete on petrol pricing; every station within a specific pricing zone must charge the exact same government-mandated rate per litre. 95 Octane is typically recommended for modern turbocharged engines and coastal driving, while 93 Octane serves as an affordable option for many naturally aspirated vehicles operational at higher altitudes inland.
Diesel Regulation Differences (50ppm & 500ppm)
Unlike petrol, retail diesel prices are not fixed by the government. The DMPR publishes a wholesale reference price, but individual service stations are legally allowed to set their own retail margins. This is why you will see different diesel prices at stations positioned right across the street from one another.
- 50ppm (0.005%): Features lower sulfur content, making it cleaner and highly recommended for modern passenger cars and commercial fleets.
- 500ppm (0.05%): High sulfur content, often utilized by older agricultural machinery or heavy industrial fleets where compatibility permits.
How to use this price information
Understanding the mechanics of the monthly price shifts allows consumers and businesses to adapt dynamically.
Budget Planning for Fleets
For logistics firms and commercial operations, fuel is often the single largest operational expense. By tracking the CEF’s daily indicators throughout the month, fleet managers can forecast their upcoming cash flow requirements well before the official DMPR press release goes live, optimizing bulk refueling orders accordingly.
When to Fill Up Your Tank
For everyday drivers, tracking the timeline protects your wallet. If an announcement indicates a drop of 200c/l, holding off on a 50-litre tank refill until Wednesday morning puts an extra R100 back into your pocket.

Market Drivers to Track
If you want to anticipate whether prices are going up or down, keep an eye on these key metrics:
- Rand/USD Exchange Rate: A stronger Rand lowers import costs.
- Global Brent Crude Prices: Higher oil costs inflate the Basic Fuel Price.
- The Slate Balance: A mechanism used by the government to absorb extreme short-term market fluctuations, which can trigger an added slate levy if the balance drops too deep into a negative deficit.
Frequently asked questions
Is the when does petrol price change in South Africa confirmed yet?
No monthly fuel price change is legally official until the Department of Mineral and Petroleum Resources issues its formal press release, usually occurring on the Monday or Tuesday immediately preceding the first Wednesday of the month. Daily data released prior to this represents rolling indicators rather than confirmed adjustments.
What data determines the monthly petrol price adjustment?
The adjustment relies on international product pricing (petrol and diesel costs on global markets), shipping and import logistics fees, the Rand/US Dollar exchange rate, and regulated domestic margins (such as retail margins, transport costs, and slate levies).
Why does the fuel price update only happen once a month?
The monthly framework is designed to protect local consumers from hyper-volatile, day-to-day market movements. By averaging out a full month’s market activity, the government ensures price stability for roughly 30 days at a time.
