South African motorists could see petrol and diesel prices fall again in August 2026 if the current trend in international oil prices and the rand exchange rate continues through the rest of July. Early Central Energy Fund data indicates an over-recovery on petrol, diesel and illuminating paraffin, but the final adjustment of the fuel price will only be confirmed by the Department of Mineral Resources and Energy at month-end.
For Gauteng households, commuters, delivery drivers and businesses, a lower fuel price would offer some relief after months of volatility at the pumps. However, the August price is not yet confirmed and could still change as global oil markets, the rand and shipping costs move during July.

Early data shows an over-recovery for petrol and diesel
The Central Energy Fund’s preliminary figures for the first week of July show a possible over-recovery of more than R2 per litre for petrol and diesel.
If those trends remain in place until the end of the fuel-price review period, the estimated changes could be:
| Fuel type | Early estimated August 2026 change |
|---|---|
| Petrol 93 | Decrease of about R2.02 per litre |
| Petrol 95 | Decrease of about R2.04 per litre |
| Diesel 0.05% | Decrease of about R2.22 per litre |
| Diesel 0.005% | Decrease of about R2.60 per litre |
| Illuminating paraffin | Decrease of about R2.52 per litre |
These are early estimates rather than final retail prices. The official fuel adjustment is usually announced by the Department of Mineral Resources and Energy shortly before the first Wednesday of the new month.
Why fuel prices may drop in August
South Africa’s monthly fuel price is mainly influenced by two factors: international petroleum product prices and the rand’s exchange rate against the US dollar.
Fuel is imported and priced internationally in dollars. When international oil prices decline, it can reduce the cost of fuel purchased by South African importers. A stronger rand can also help because fewer rand are needed to buy the same dollar-priced fuel products.
The preliminary data follows lower international oil prices after concerns around supply disruptions in the Middle East eased. Global fuel markets remain sensitive to geopolitical developments, shipping routes and decisions by major oil-producing countries, which means the outlook can change quickly before the end of July.
The final fuel-price calculation also includes other regulated components, such as transport costs, wholesale margins, taxes and levies.
July fuel changes set the baseline
Fuel prices already declined significantly on 1 July 2026, with petrol falling by about R2 per litre and diesel dropping by more than R3 per litre in some categories.
The July adjustment came despite the phasing out of temporary fuel levy relief. The Department of Mineral Resources and Energy confirmed that the full general fuel levies were reinstated from 1 July, with petrol carrying a levy of 429 cents per litre and diesel carrying a levy of 416 cents per litre.
This means any further reduction in August would largely depend on the performance of the rand and international fuel prices, rather than another government levy intervention.
What an R2-per-litre cut could mean for motorists
A reduction of around R2 per litre would make a noticeable difference for motorists who travel regularly for work, school, business or family commitments.
For example, a driver filling a 45-litre petrol tank could save roughly R90 per fill-up if petrol decreases by R2 per litre. A motorist using 60 litres could save about R120.
The actual saving would depend on the final price adjustment, the fuel grade used and how much fuel a vehicle consumes each month.
Gauteng has some of the country’s busiest road networks, with commuters travelling daily between Johannesburg, Pretoria, Ekurhuleni, Sedibeng and the West Rand. Fuel costs also affect public transport operators, delivery services, logistics companies and small businesses that rely on vehicles to move goods and staff.
What This Means for Gauteng Residents
A possible August fuel-price cut could reduce transport costs for households and businesses, particularly where people rely on private vehicles or taxis for daily travel.
Lower diesel prices may also ease pressure on businesses that use trucks, generators and delivery fleets. Diesel is a major input cost in freight, food distribution, construction and manufacturing, so changes can affect the wider cost of moving goods across Gauteng.
However, a lower fuel price does not automatically mean lower prices in shops or lower taxi fares. Those costs are influenced by several factors, including wages, food prices, operating costs and individual business decisions.
Residents should also note that fuel prices differ slightly between coastal and inland areas. Gauteng motorists generally pay an inland price because of the cost of transporting fuel from coastal ports to the province.
Why the August outlook can still change
The current over-recovery reflects only the first part of the July review period. The final adjustment will depend on market movements over the next few weeks.
Factors that could change the outlook include:
- A sharp increase in international crude oil or refined fuel prices
- A weaker rand against the US dollar
- Further conflict or supply disruptions in major oil-producing regions
- Higher shipping and insurance costs for fuel cargoes
- Changes in local fuel levies or regulated fuel-price components
Motorists should therefore treat the current estimates as an indication of the direction of prices, not a confirmed August decrease.
When will August fuel prices be confirmed?
The Department of Mineral Resources and Energy is expected to announce the official August 2026 fuel-price adjustment near the end of July or at the start of August.
The new fuel prices are expected to take effect on Wednesday, 5 August 2026, subject to the department’s official announcement.
The Central Energy Fund updates its daily fuel-price outlook during the month, but the figures can move as international markets and the exchange rate change.
FAQ: August 2026 Fuel Prices
Will petrol definitely be cheaper in August 2026?
No. Early data indicates a possible decrease, but the final price will only be confirmed after the July fuel-price review period ends.
How much could petrol decrease?
Current preliminary figures point to a possible reduction of about R2.02 per litre for 93 octane petrol and R2.04 per litre for 95 octane petrol.
Why is diesel expected to fall more than petrol?
Diesel and petrol are priced using different international product benchmarks. Current data shows a stronger over-recovery for diesel than for petrol.
When will the new fuel price take effect?
If confirmed, the August adjustment is expected to take effect on Wednesday, 5 August 2026.
Why do Gauteng motorists pay more than coastal motorists?
Gauteng’s inland fuel price includes transport costs associated with moving fuel from coastal ports to inland markets.
The Department of Mineral Resources and Energy will publish the final August fuel-price adjustment once the July review period closes. Until then, the current figures remain an early indication that motorists could receive further relief at the pumps.
