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.
Understanding the official diesel wholesale price in South Africa is critical for transport operators, fleet managers, agricultural businesses, and individual vehicle owners looking to manage their fuel expenses effectively. Unlike petrol, which is strictly regulated at a fixed retail pump price by the government, diesel pricing is set at a wholesale level. This structural difference creates unique cost management opportunities and regional variations across the country.
Diesel Wholesale Price: Current Diesel Price
The Department of Mineral and Petroleum Resources (DMPR) adjusts South Africa’s fuel prices on the first Wednesday of every month. The official wholesale prices reflect the baseline costs before retail service stations add their operational margins.
The tables below detail the official wholesale diesel prices across different regional zones and sulfur grades.
Official Inland Diesel Wholesale Prices
Effective Date: 2 September 2026 | Units: Cents per Litre (c/l) and Rands per Litre (R/l)
| Fuel Grade | Price (c/l) | Price (R/l) |
| Diesel 50ppm (0.005% Sulfur) | 25,17.170 c/l | R29.56 per litre |
| Diesel 500ppm (0.05% Sulfur) | 24,78.770 c/l | R29.11 per litre |
Official Coastal Diesel Wholesale Prices
Effective Date: 2 September 2026 | Units: Rands per Litre (R/l)
| Fuel Grade | Price (R/l) |
| Diesel 50ppm (0.005% Sulfur) | R28.68 per litre |
| Diesel 500ppm (0.05% Sulfur) | R28.24 per litre |

50ppm vs 500ppm Diesel
South Africa splits its commercial diesel distribution into two primary types based on sulfur content: 50ppm (0.005%) and 500ppm (0.05%). This distinction dictates engine compatibility, environmental impact, and baseline cost profiles.
Wholesale Grade Breakdown
- 50ppm (0.005% Sulfur): Highly refined, cleaner-burning fuel required by modern turbo-diesel engines and passenger vehicles. It commands a premium price due to the extensive refining processes needed to extract sulfur. For localized tracking, see the diesel 50ppm price page.
- 500ppm (0.05% Sulfur): A high-sulfur formulation typically used in older engines, heavy agricultural machinery, and specific industrial generators. Because it requires less processing, its wholesale baseline remains cheaper. For focused monitoring, visit the diesel 500ppm price hub.
Choosing the incorrect grade can affect vehicle longevity and fleet performance, so operators must align procurement with engine manufacturer specifications.
Inland vs Coastal Diesel Price
Regional price variations are fundamentally driven by logistics. Because South Africa imports a substantial volume of its crude oil and refined petroleum products, the cost to transport fuel from coastal ports into the interior significantly elevates inland wholesale figures.
The Transport Tariff Factor
The baseline price differential between coastal and inland zones represents the cost of utilizing pipelines, rail infrastructure, and road tankers to pump fuel up to Gauteng and surrounding interior provinces. As a result, inland transport operations naturally face higher baseline wholesale costs compared to their coastal counterparts.

Wholesale vs Pump-Price Context
The most vital regulatory distinction for commercial operators is that the DMPR does not set a maximum retail price for diesel.
Why Pump Prices Vary
While petrol stations must charge the exact government-legislated pump price, the retail margin for diesel is deregulated. Retailers use the official DMPR wholesale price as their starting cost and add an independent retail margin to cover land costs, labor, and local competitive factors. This structural setup is the core reason why diesel prices vary between stations.
For large commercial operations purchasing in volume via road tankers, the transaction is governed directly by the bulk diesel price South Africa market, whereas individual drivers and smaller operators rely on local competitive pricing tracked through the diesel retail price South Africa network.
Diesel Forecast and History
Because local wholesale pricing is bound to global dynamics, values swing monthly based on international indicators. The final adjustments depend on daily tracking data supplied by the Central Energy Fund (CEF).
Key Cost Drivers
- International Oil Prices: Brent crude movements dictate the Basic Fuel Price (BFP). Drops in global crude reduce refining costs, whereas international shortages lift wholesale baselines.
- The Rand/US Dollar Exchange Rate: Since global fuel products are traded in US Dollars, a strengthening Rand cushions local wholesale baselines, while a weakening local currency escalates import expenses.
- The Slate Balance: Under- or over-recoveries are managed through a self-adjusting slate levy mechanism, protecting the local industry from sudden market shocks.

Calculator and Fleet-Use Links
For commercial fleets, transportation companies, and agricultural operators, fuel represents one of the largest operational expenses. Proper logistics management requires accurate, continuous calculation tools to budget effectively.
Managing Fleet Consumption
When budgeting for logistics routes or corporate fleet allocations, operators require exact data points to construct accurate fuel expenditure models:
- Total trip or monthly operational distance
- Average fleet vehicle consumption (litres per 100km)
- The applicable wholesale or retail price per litre for the current month
- Specific operating regions (Inland vs. Coastal)

Frequently Asked Questions
What is the diesel wholesale price?
The diesel wholesale price is the official baseline cost set monthly by the DMPR. It acts as the purchasing price for commercial wholesalers and the foundation upon which retail fuel stations calculate their individual pump margins.
What is the difference between 50ppm and 500ppm?
The primary difference is the sulfur content: 50ppm contains 0.005% sulfur, making it cleaner and optimal for modern passenger vehicles. 500ppm contains 0.05% sulfur, which is less refined and suited for heavy industrial or older agricultural equipment.
Do inland and coastal diesel prices differ?
Yes. Inland wholesale prices are higher than coastal prices because they include the logistical transport tariffs required to move fuel from coastal entry ports via pipeline, rail, or road into South Africa’s interior regions.
When should diesel prices be updated?
Official adjustments are released by the DMPR and implemented at midnight on the first Wednesday of every month, changing according to global oil pricing and the performance of the Rand.
