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, deciding whether to reach for the 93 or 95 octane nozzle can feel like a guessing game. Choosing the correct fuel grade directly impacts your vehicle’s health and your monthly budget.
This decision guide clears up the confusion around which petrol should I use, outlines the real financial differences between inland and coastal zones, and shows you how to find your car’s perfect match without overpaying at the pump.
Which Petrol Should I Use: Current Price
The primary factor on every motorist’s mind is cost. In South Africa, fuel prices are regulated by the Department of Mineral and Petroleum Resources (DMPR) and adjusted on the first Wednesday of every month.

93 vs 95 Petrol Explained
The numbers 93 and 95 don’t stand for quality, purity, or power. Instead, they indicate the fuel’s octane rating.
What is Octane?
An octane rating measures how much compression a fuel can withstand before igniting inside your engine cylinders.
- High-performance or turbocharged engines compress the air-fuel mixture tightly to create more power. These engines require 95 octane petrol because it resists premature ignition under high pressure.
- Standard, naturally aspirated engines do not compress fuel to extreme levels, making 93 octane petrol perfectly safe and efficient.
If you use a fuel with an octane level lower than what your engine demands, it can trigger “knocking” or “pinging”—a premature detonation that can harm your engine over time. However, if your vehicle is rated for 93 octane, filling up with 95 provides no mechanical benefit, extra fuel efficiency, or additional speed.
ULP and LRP Terms
When looking at fuel pumps, you will see suffixes like ULP (Unleaded Petrol) and LRP (Lead Replacement Petrol).Since leaded fuel was phased out across South Africa to protect public health and the environment, ULP has become the standard for modern vehicles equipped with catalytic converters. LRP is primarily kept at selected stations for older, vintage engines that require specific valve-seat protection.

Inland vs Coastal Grade Pricing
Have you ever noticed that a litre of fuel costs noticeably less in Durban or Cape Town than it does in Johannesburg or Pretoria? This geographical discrepancy comes down to transport costs and government pricing zones.
[Port / Sea Level] ---> Pipeline / Rail / Road Transport ---> [Highveld / Inland]
(Lower Price) (Higher Price)
Because South Africa’s crude oil and refined petroleum products arrive by sea, coastal regions sit directly at the source. Transporting that fuel up to the Highveld requires extensive pipeline infrastructure, rail networks, and road tankers. The cost of this transport is factored directly into the regulated inland price.
Furthermore, the price gap between the two grades behaves differently depending on where you live:
- Coastal Pricing: Both 93 and 95 ULP are widely available at the coast. However, because 95 is the national “price-marker” grade used to calculate base fuel import margins, the differential varies slightly each quarter.
- Inland Pricing: In inland regions, 93 ULP serves as a highly economical choice for drivers whose commuter vehicles don’t require maximum compression resistance.
For real-time local differences, keep an eye on our dedicated 93 petrol price and 95 petrol price directories.
Which Petrol Grade Should You Use?
The answer to what petrol should I put in my car is found in one definitive place: your vehicle owner’s manual, or on the inside of your fuel filler cap flap.
Manufacturers design engines around specific fuel parameters. Let’s break down the rules of thumb based on altitude and engine type:
Altitude and Engine Type Guide
- Naturally Aspirated Engines at High Altitude (Inland): Atmospheric pressure is lower on the Highveld (around 1,500 meters above sea level). Because the air is thinner, engines naturally draw in less air, lowering the effective compression inside the cylinders. Consequently, most naturally aspirated (non-turbo) cars that require 95 at the coast can easily and safely run on 93 inland.
- Turbocharged or Supercharged Engines: If your car features a modern turbocharger (common in eco-boost, TSI, or sports models), altitude does not change its fuel requirements. Turbochargers mechanically force air into the engine, maintaining high compression regardless of elevation. If your manual says 95, you must use 95 petrol.
- Coastal Driving: At sea level, air density is high. If your car’s manufacturer lists 95 octane as the recommended or minimum requirement, stick strictly to 95 to protect the engine from pre-ignition knock.
Rule of Thumb: If your vehicle manual specifies a minimum requirement of 95 octane, do not try to save pennies by switching to 93. If your manual indicates that 91 or 93 octane is acceptable, filling up with 95 is simply spending extra money for zero real-world reward.
If you are thinking about changing grades next time you fill up, weigh your vehicle’s specific guidelines against the cost considerations detailed in our guide on can I use 93 instead of 95 petrol.
Monthly Increase or Decrease Context
South Africa’s monthly fuel price changes fluctuate based on two main global inputs: the international price of Brent crude oil and the R/$ (Rand/US Dollar) exchange rate.
When global oil prices drop or the Rand strengthens, we experience a monthly price decrease (known as an over-recovery). When oil prices climb or the local currency slips, a price increase follows (under-recovery).
To figure out how these monthly shifts impact your household budget, you can estimate your regular costs using a few data points:
- Distance Covered: Your total kilometres driven per month (e.g., 1,500 km).
- Fuel Consumption: How many litres your car drinks per 100 km (e.g., 7.5 L / 100 km).
- Price per Litre: The current retail pump price based on your chosen grade and region.
Example Fuel Estimation
Let’s see a practical scenario for an inland commuter driving a hatchback that handles 93 octane smoothly:
- Monthly Commute: 1,200 km
- Average Fuel Consumption: 6.0 litres per 100 km
- Total Monthly Litres Needed:$$(1200 \div 100) \times 6.0 = 72 \text{ litres}$$
- Estimated Cost with September 2026 Inland 93 Price (R26.76/L):$$72 \times R26.76 = R1,867.68$$
By making the informed choice to use 93 ULP instead of 95 ULP (saving 16 cents per litre inland), this driver saves a small but steady amount on every single tank.

Frequently Asked Questions
What does “which petrol should I use” mean for drivers?
It means identifying the specific fuel octane rating (93 or 95) that matches your vehicle’s engine design. Picking the right grade ensures your engine runs cleanly, stays free of internal damage, and avoids wasting money on unnecessary high-octane premium blends.
Should drivers choose 93 or 95?
Always prioritize your vehicle owner’s manual. If your car has a standard engine and you drive inland, 93 octane is highly cost-effective and perfectly safe. If your car has a turbocharger, high-performance tuning, or you live at the coast, 95 octane is generally required to avoid engine knock.
Does fuel grade affect price?
Yes. In South Africa, 95 octane petrol is more expensive than 93 octane petrol due to the refined manufacturing requirements and basic fuel price formulas set by the DMPR. Choosing 93 when your car safely permits it can lower your overall fueling expenses.
