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.
If you have ever driven from Johannesburg down to Durban or Cape Town, you have probably noticed a satisfying drop in the cost of filling up your tank as you near the ocean. In South Africa, fuel prices are strictly regulated by the Department of Mineral and Petroleum Resources (DMPR), but they are not uniform across the country.
The primary difference between inland and coastal petrol prices comes down to transportation costs. Because crude oil and refined fuel arrive via coastal ports, inland regions must factor in the cost of transporting that fuel hundreds of kilometres via pipelines, rail, and road networks. This creates two distinct pricing zones across South Africa.
Inland vs Coastal Petrol Prices: Current Price
The table below shows the official regulated pump prices for petrol and wholesale diesel prices across South Africa’s primary inland and coastal pricing zones.
Official Fuel Prices (Effective 2 September 2026)
| Fuel Type / Grade | Inland Price | Coastal Price | Difference |
| 93 Unleaded Petrol | R26.76 / L | R25.97 / L | 79 c/l |
| 95 Unleaded Petrol | R26.92 / L | R26.05 / L | 87 c/l |
| Diesel 0.05% (500ppm)* | R29.11 / L | R28.24 / L | 87 c/l |
| Diesel 0.005% (50ppm)* | R29.56 / L | R28.68 / L | R1.26 / L |
*Note on Diesel Pricing: Unlike petrol, which has a strictly regulated retail pump price, diesel prices shown are official wholesale baselines. Retailers add their own margins, meaning actual prices at the pump will vary slightly from station to station.

Inland, Coastal, or Local Zone Context
South Africa is divided into several Magisterial District Zones (MDZs) to calculate localized transport costs accurately.
- Coastal Zone (Zone 1A): Covers major port cities like Durban, Cape Town, Port Elizabeth (Gqeberha), and East London. Fuel is at its cheapest here because it requires no overland pipeline transport.
- Inland Zone (Zone 9C / Gauteng): Covers Johannesburg, Pretoria, and surrounding economic hubs. This zone carries a higher tariff tier due to the extensive pipeline network from Durban to the highveld.
It is important to understand that your exact local municipal price depends on which MDZ your town falls into. A station in the Free State or North West might have a minor variation compared to central Gauteng, but they all fit broadly under the “Inland” structural baseline.
Compare Petrol, Diesel, and Other Fuels
While both petrol and diesel are subject to zone-based transport costs, they handle grades differently:
Petrol Grades (93 vs 95)
Inland motorists have access to both 93 Unleaded and 95 Unleaded petrol grades. At higher altitudes (inland), the lower atmospheric pressure changes the combustion characteristics of your engine, making 93 octane perfectly efficient for most naturally aspirated vehicles. On the coast, lower-octane 93 fuel is generally unavailable or highly restricted because engines require 95 octane to prevent engine knocking under heavier sea-level air density.
For a deeper breakdown on specific grades, see our dedicated 93 petrol price and 95 petrol price tracking pages.
Diesel Grades (50ppm vs 500ppm)
Diesel fuel does not experience octane changes based on altitude, but transport costs still apply across the inland and coastal zones. Commercial fleets operating across provincial borders must account for these regional wholesale cost steps when calculating long-haul freight operations.
Why This Area Differs From Other Regions
The core reason for the price gap is the Zone Differential managed by the DMPR.
When crude oil is imported or refined at the coast, it incurs a Basic Fuel Price (BFP). The government then adds local costs, fuel levies, retail margins, and the transport tariff. The inland price is structurally higher simply to pay for the infrastructure required to pump fuel uphill to the reef.
Travel and Fill-Up Decision Guidance
If you are planning a road trip between the coast and the inland provinces, you can save money by planning your fuel stops strategically:
- Heading to the Coast: Fuel up with just enough petrol to get you comfortably past the mountain passes. Once you hit the coastal pricing zones, do your major fill-ups to take advantage of the lower per-litre rates.
- Returning Inland: Fill your tank to the absolute maximum right before you leave the coastal zone. This ensures you buy as much fuel as possible at the lower price before crossing back into the more expensive inland zones.
- Check Vehicle Suitability: Never switch your fuel grade solely to save money if it contradicts your manufacturer’s specifications. Always consult your vehicle’s manual to verify whether it can safely run on 93 or requires a minimum of 95 octane.

Frequently Asked Questions
What does inland vs coastal petrol prices mean for drivers?
It means that the price of petrol is legally regulated based on your geographical distance from the nearest port. Drivers inland pay a premium per litre to cover the logistical cost of transporting fuel from coastal points of entry up to the interior provinces.
Should drivers choose 93 or 95?
You should always choose the fuel grade recommended in your vehicle’s owner manual. While modern turbocharged engines typically manage their own timing, naturally aspirated vehicles operating at sea level generally require 95 octane to prevent engine knock, whereas many can safely run on 93 at higher altitudes.
Does fuel grade affect price?
Yes. 95 Unleaded petrol features a higher basic fuel price differential compared to 93 Unleaded, meaning 95 is consistently the more expensive option regardless of whether you are purchasing it inland or at the coast.
