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.
When pulling up to a filling station in South Africa, drivers face a distinct choice at the pumps: 93 octane or 95 octanefuel. Understanding the practical differences between these fuel grades impacts both your wallet and your vehicle’s engine health.
This guide outlines the core differences, official monthly costs, and regional availability to help you determine which petrol should I use for your vehicle.
93 vs 95 Petrol: current price
South African fuel prices are strictly regulated and adjusted on the first Wednesday of every month by the Department of Mineral and Petroleum Resources (DMPR). The table below outlines the official retail pump prices.
Official Fuel Prices (Effective September 2026)
| Petrol Grade | Inland Pump Price (c/l) | Coastal Pump Price (c/l) |
| 93 Petrol | 2,676.00 c/l (R26.76/L) | 2,597.00 c/l (R25.97/L) |

93 vs 95 petrol explained
The core difference between the two grades centers on fuel stability rather than raw power or purity.
What is Octane Rating?
To understand the grades, you need to know what is octane rating. An octane rating measures a fuel’s resistance to “knocking” or “pinging.” Knocking occurs when the fuel-air mixture ignites prematurely inside the engine cylinders, which can damage internal engine components over time.
- 93 Octane: Features lower resistance to detonation, making it perfectly stable for standard, naturally aspirated commuter engines at higher altitudes.
- 95 Octane: Features a higher resistance to detonation, required by high-compression engines and turbochargers to operate smoothly without pre-ignition.
Fuel Terminology: ULP and LRP
When looking at petrol grades South Africa, pumps use specific acronyms:
- ULP: If you have ever wondered what does ULP mean, it stands for Unleaded Petrol, which is the modern standard for all unleaded passenger vehicles.
- LRP: Drivers asking what is LRP petrol will find it refers to Lead Replacement Petrol, designed for older, vintage vehicle engines that require valve-seat protection.
Inland vs coastal grade pricing
Fuel pricing differs dramatically depending on your geographical zone due to the regulated cost of transporting fuel from coastal ports to the interior via pipelines and rail networks.
Regional Availability and the Coast
If you are wondering is 93 petrol available at the coast, the answer is generally no. Because coastal atmospheric pressure is higher, engines require a higher octane rating to prevent knocking. As a result, 95 octane is the standard grade provided at coastal pumps, while both 93 and 95 are available inland.
Because inland zones require transport logic additions, the 93 petrol price and 95 petrol price carry a premium compared to coastal filling stations.
Which petrol grade should you use?
Your primary guide should always be your vehicle’s owner manual or the label inside your fuel cap.
Performance and Efficiency Truths
There are common misconceptions regarding fuel choice:
- Does 95 petrol give better performance? A frequent question is does 95 petrol give better performance. The truth is that putting 95 octane into an engine designed for 93 octane will not give you extra horsepower or clean your engine better. It simply resists detonation that your engine isn’t built to create.
- Does 95 petrol last longer? When evaluating if does 95 petrol last longer than 93, standard vehicle testing proves it does not improve fuel economy unless your vehicle’s manufacturer specifically dictates 95 octane.
If your manual permits both, using the cheaper unleaded 93 price tier inland is a safe, budget-conscious decision.
Monthly increase or decrease context
The underlying cost structure shifts monthly based on international crude oil prices and the Rand/US Dollar exchange rate. Because the price gap per litre fluctuates, understanding how your grade choice translates to monthly expenditure helps control your household budget.

Frequently asked questions
Can I use 93 instead of 95 petrol?
Whether can I use 93 instead of 95 petrol depends entirely on your engine. If your manufacturer mandates 95 octane (common in turbocharged or high-performance models), using 93 can cause severe engine knocking and potentially void your mechanical warranty. If your manual states 93 octane is acceptable, you can use it safely.
Can you mix 93 and 95 petrol?
Yes, can you mix 93 and 95 petrol safely if your car is rated for 93 octane. Mixing the two results in an interim octane rating somewhere between 93 and 95. However, if your car strictly requires 95 octane, do not top up with 93 octane, as it lowers the overall rating below the safe threshold your engine requires.
