South Africa Fuel Price Adjustment August 2026: Petrol Down, Diesel Up

• Petrol prices will decrease by 52.00 cents per litre across both 93 and 95 octane grades from August 5, 2026.
• Diesel prices are set to increase significantly, with 0.05% sulphur diesel rising by 138.44 cents per litre and 0.005% sulphur diesel by 123.44 cents per litre.
• Illuminating paraffin will see substantial increases, with wholesale prices up by 152.00 cents per litre and the SMNRP by 203.00 cents per litre.
• The Slate Levy, applied to petrol and diesel, will be 61.38 cents per litre, a decrease of 52.56 cents per litre from its previous level.
• LPGas maximum retail prices will decrease by 441.00 cents per kilogram nationally, with a larger reduction of 503.00 cents per kilogram in the Western Cape.

These significant adjustments, particularly the substantial increases for diesel and illuminating paraffin, carry considerable implications for businesses operating within South Africa's transport, logistics, and energy sectors.

The Minister of Mineral and Petroleum Resources has confirmed significant adjustments to South Africa's fuel prices, effective from August 5, 2026. These monthly revisions, influenced by a blend of international and local market dynamics, will see a decrease in petrol prices while diesel and illuminating paraffin users face substantial increases. This South Africa fuel price adjustment August 2026 marks a mixed outcome for consumers and industries alike.

Specifically, both grades of petrol, ULP and LRP 93 and 95, will experience a uniform decrease of 52.00 cents per litre. In contrast, diesel prices are set to climb, with 0.05% sulphur diesel increasing by 138.44 cents per litre and 0.005% sulphur diesel by 123.44 cents per litre. Illuminating paraffin will also see a sharp rise, with wholesale prices up by 152.00 cents per litre and the Single Maximum National Retail Price (SMNRP) increasing by 203.00 cents per litre. The LPGas price South Africa August 2026 will generally decrease by 441.00 cents per kilogram, with a more pronounced reduction of 503.00 cents per kilogram specifically for the Western Cape region.

Several global and domestic factors underpinned this DMPR fuel price announcement 2026. On the international crude oil front, the average Brent Crude oil price saw a decrease from 86.53 US Dollars to 82.37 US Dollars during the review period. While renewed US/Iran tensions briefly pushed prices towards the $100 mark, this upward pressure was mitigated by a previous month's significant price drop, a ceasefire Memorandum of Understanding between the US and Iran, and a general decline in global crude oil demand.

However, the international product prices for refined fuels presented a more complex picture. While petrol prices decreased, diesel and illuminating paraffin saw increases. This divergence is primarily attributed to supply shortages stemming from the Russia/Ukraine conflict, which led to diesel export restrictions by Russia, compounded by Middle East refineries operating below their full capacity. These dynamics resulted in a 6.08 cents per litre lower contribution to the Basic Fuel Price (BFP) for petrol, but an increase of 182.62 cents per litre for diesel and 143.32 cents per litre for illuminating paraffin. Additionally, the Rand depreciated slightly against the US Dollar, moving from 16.34 to 16.46 Rand per USD on average, contributing an additional 6.37 c/l to petrol's BFP, 8.14 c/l to diesel's, and 7.89 c/l to illuminating paraffin's.

Propane and Butane prices also experienced a decrease internationally during this period.

A significant component of the petrol diesel price increase South Africa 2026 calculations is the Slate Levy. This mechanism addresses the cumulative negative balance incurred by the industry. As of the end of June 2026, this cumulative slate for petrol and diesel stood at a negative R7.418 billion. Consequently, in adherence to the Self-Adjusting Slate Levy Mechanism, a levy of 61.38 cents per litre will be applied to the price structures of both petrol and diesel from August 5, 2026. Notably, this South Africa Slate Levy August 2026 represents a decrease of 52.56 cents per litre from its previous level of 113.94 cents per litre.

Regarding LPGas, specific pricing for imports via the Port of Saldanha Bay in the Western Cape has also been set. The Maximum Refinery Gate Price (MRGP) for LPGas will be R14,562.59 per metric ton, while the Maximum Retail Price (MRP) will be R35.81 per kilogram, both effective from August 5, 2026. These figures contribute to the overall LPGas price South Africa August 2026 structure.

These significant adjustments, particularly the substantial increases for diesel and illuminating paraffin, carry considerable implications for businesses operating within South Africa's transport, logistics, and energy sectors. Companies in these industries will need to meticulously review their existing contractual agreements and financial projections to absorb or pass on these altered operational costs, especially considering the ongoing impact of the Slate Levy. The differential impact on various fuel types underscores the necessity for strategic planning and risk assessment in a volatile energy market.

While petrol users will benefit from a price reduction, the upward trend for diesel and paraffin could exert inflationary pressure on goods and services reliant on these fuels for production and distribution. The detailed fuel price schedule for different Magisterial District Zones is anticipated to be published on Tuesday, August 4, 2026, providing further localized clarity on these nationwide changes.

Compliance officers and legal counsel advising businesses in South Africa's transport, logistics, and energy sectors should review contractual agreements and financial forecasts to account for the significant August 2026 fuel price adjustments, particularly the diesel and illuminating paraffin increases, and the ongoing impact of the Slate Levy on operational costs.
