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.

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.

Fuel Terminology: ULP and LRP

When looking at petrol grades South Africa, pumps use specific acronyms:

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:

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.
