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.

Inland Fuel Price Today: Complete South Africa Reef Petrol and Diesel Breakdown

South African motorists driving in inland regions—including Gauteng, the Free State, Mpumalanga, North West, and Limpopo—pay a distinct rate for fuel compared to coastal coastal areas. Understanding current inland petrol and diesel prices, how transport zone differentials affect the pump price, and what factors drive monthly adjustments is essential for budgeting and fleet management.

Below is the official breakdown of inland fuel prices today, what causes inland price variance, and what to expect in the upcoming monthly pricing cycle.

Current Inland Fuel Prices in South Africa

Fuel prices in South Africa are adjusted on the first Wednesday of every month by the Department of Mineral and Petroleum Resources (DMPR).

The table below outlines current inland (Zone 9C / Reef) retail petrol and wholesale diesel prices:

Fuel Type	Grade / Specification	Current Inland Price (per Litre)
Unleaded Petrol 93	93 ULP / LRP	R26.76
Unleaded Petrol 95	95 ULP	R26.92
Diesel 50ppm	0.005% Sulphur (Wholesale)	R29.56
Diesel 500ppm	0.05% Sulphur (Wholesale)	R29.11
Illuminating Paraffin	Wholesale	R19.85

Note: Diesel prices are published as wholesale benchmarks. Final retail pump prices vary between individual service stations and retail brands.

Why Inland Fuel Prices Are Higher Than Coastal Prices

If you drive in Johannesburg or Pretoria, you will notice that petrol costs more per litre than in Cape Town or Durban. This price difference is regulated and structural, governed by the South African fuel pricing model.

1. Zone Differential (Transport Costs)

South Africa imports refined petroleum products and crude oil via coastal ports like Durban and Richards Bay. Transporting fuel from coastal ports and coastal refineries to inland economic hubs requires pipelines (operated by Transnet), rail, and road transport.

The government calculates a Zone Differential (Zone 9C for Gauteng) that is added to the Basic Fuel Price (BFP) to recover the logistics cost of moving fuel inland.

2. Octane Availability

93 Octane Unleaded (93 ULP): Primarily sold in inland regions. Due to higher altitude and lower air density on the Highveld, engine compression requirements are lower, making 93 octane safe and efficient for naturally aspirated petrol engines.
95 Octane Unleaded (95 1ULP): Available nationwide, but mandatory at the coast where higher atmospheric pressure requires 95 octane to prevent engine knocking.

Factors Influencing Inland Fuel Prices

Inland fuel prices fluctuate monthly based on two primary external drivers and official regulatory levies:

International Crude Oil Prices: Brent Crude oil prices directly dictate the Basic Fuel Price (BFP). Spikes in international refined product prices increase import costs.
USD / ZAR Exchange Rate: Because petroleum products are traded globally in US Dollars, any depreciation of the South African Rand against the US Dollar increases the local cost per litre.
Government Levies and Taxes:
- General Fuel Levy (GFL): Fixed tax allocated to National Treasury.
- Road Accident Fund (RAF) Levy: Fixed tax dedicated to funding the RAF.
- Customs & Excise Levy: Standard indirect tax.
- Slate Account Balance: Used to absorb temporary under- or over-recoveries in monthly fuel trading balances.

Upcoming Fuel Price Outlook

Based on mid-month and late-month Central Energy Fund (CEF) data, the next monthly adjustment on 2 September 2026 is projected to bring mixed results for inland drivers:

Petrol (93 & 95 ULP): Projected decrease of 14c to 19c per litre, offering minor relief at the pump.
Diesel (50ppm & 500ppm): Projected increase of R1.42 to R1.60 per litre, driven by global middle-distillate demand shifts and international refinery margins.

Practical Tips for Inland Drivers to Save Fuel

Driving at altitude and navigating dense Gauteng or Highveld traffic increases fuel consumption. You can reduce your monthly fuel bill by implementing key efficiency habits:

Maintain Correct Tyre Pressure: Altitude temperature swings affect tyre pressure. Under-inflated tyres increase rolling resistance and boost fuel usage by up to 5%.
Use the Correct Octane Grade: If your vehicle’s manufacturer permits 93 ULP (standard for most non-turbocharged engines inland), stick to 93 ULP rather than paying the premium for 95 ULP.
Smooth Acceleration & Momentum: Avoid sudden bursts of speed in heavy urban traffic. Gentle throttle application saves up to 15% on daily fuel consumption.
Combine Short Trips: Cold-engine starts consume significantly more fuel. Plan errands sequentially to ensure the engine operates at optimal running temperature.
