Get the latest August 2026 South Africa petrol price update. See the expected petrol and diesel price changes, why fuel prices are falling, and when the new prices take effect.
South Africa’s August 2026 Petrol Price Update
South African motorists are still expected to receive fuel price relief in August 2026, although the anticipated reductions have become smaller following a rise in international oil prices.
The latest mid-month projections indicate that petrol and diesel prices are likely to decrease, but ongoing geopolitical tensions and higher crude oil prices have reduced the size of the expected cuts.
Expected Petrol and Diesel Prices for August 2026
According to the latest projections, motorists can expect:
| Fuel Type | Expected Change |
|---|---|
| Petrol 93 | -R1.30 per litre |
| Petrol 95 | -R1.26 per litre |
| Diesel 0.05% | -47 cents per litre |
| Diesel 0.005% | -74 cents per litre |
| Illuminating Paraffin | -73 cents per litre |
These figures remain provisional until the Department of Mineral and Petroleum Resources announces the official adjustment.
When Will the New Petrol Price Take Effect?
South Africa adjusts fuel prices once every month.
The official August 2026 fuel prices are expected to come into effect on the first Wednesday of August 2026, after the government publishes the final fuel price adjustments.
Why Are Fuel Prices Falling?
Several factors continue to support lower fuel prices:
- A stronger South African Rand against the US Dollar.
- Lower average international refined fuel prices during much of the pricing period.
- Earlier declines in global crude oil prices.
However, the expected reductions have been partially offset by:
- Rising Brent crude oil prices.
- Increased geopolitical tensions affecting global oil supply.
- Market uncertainty surrounding international energy production.
What Determines Petrol Prices in South Africa?
South Africa’s monthly fuel prices are based on several key factors:
International Oil Prices
South Africa imports most of its crude oil. When international oil prices rise, local fuel prices generally increase.
Rand/Dollar Exchange Rate
Oil is traded globally in US Dollars. A stronger Rand usually helps reduce fuel prices, while a weaker Rand makes imported fuel more expensive.
Government Levies
Fuel prices also include:
- General Fuel Levy
- Road Accident Fund (RAF) Levy
- Wholesale and retail margins
- Storage and transport costs
These components form part of the final pump price paid by motorists.
How Much Could You Save?
If the projected reductions are confirmed:
- A 50-litre petrol tank could cost approximately R63 to R65 less to fill.
- A 60-litre tank could save motorists around R75 to R78.
- Businesses operating fleets could also benefit from lower diesel costs.
What This Means for South African Consumers
Lower fuel prices can reduce transport costs across multiple industries, helping to ease pressure on household budgets. Over time, cheaper fuel may also contribute to slower increases in the prices of goods transported by road.
However, economists warn that global oil markets remain volatile, meaning future fuel price movements will continue to depend on international events and currency fluctuations.

Final Thoughts
Motorists are still likely to benefit from lower fuel prices in August 2026, but the relief is expected to be less significant than initially forecast.
