Official petrol price increases for June announced

The Department of Mineral and Petroleum Resources has announced the official fuel price adjustments for June 2026.

The average international product price for petrol and diesel decreased during the period under review.

Oil prices traded at a high but relatively stable value of around $100 per barrel in May, dropping to $89 as the United States and Iran entered peace talks.

At the same time, the rand appreciated slightly against the US dollar compared to the previous period.

Between 30 April and 28 May 2026, the rand maintained an average value of R16.51/USD, compared to R16.64/USD the month prior.

This led to a lower contribution to the Basic Fuel Price of petrol and diesel by 12.070c/l and 14.164c/l, respectively.

In line with the provisions of the Self-Adjusting Slate Levy Mechanism, a Slate Levy of 157.74c/l will be implemented into the price structures of petrol and diesel.

This is an increase from the previous levy of 122.70c/l, resulting in a 35.040c/l increase in the price of both fuels.

The end result is that diesel users will see an appreciable drop at the pumps this month, though petrol users won’t be as lucky.

The main reason for this is the introduction of the General Fuel Levy (GFL), which was suspended in April and May as part of a government relief measure to cushion the impact of the fuel price hikes.

The GFL was reduced by R3 per litre for petrol and R3.93 per litre for diesel. However, the Minister of Finance has approved the decision to partially re-add the fuel tax this June.

Consequently, R1.50 will be added back to the cost of petrol, while diesel will receive a R1.93 increase. The remainder of the GFL will be reintroduced in July.

While the savings on diesel are large enough to mitigate the return of the GFL, petrol will, unfortunately, experience a price increase because of the fuel tax.

What you’re paying this June

The new fuel price adjustments will take effect later this week, on Wednesday, 3 June 2026.

Both grades of petrol will increase by R1.43 per litre. Had it not been for the GFL, petrol users would have experienced a marginal reduction of 7c per litre.

Things are much better for diesel motorists, as prices are dropping by between R2.62 per litre and R3.25 per litre.

These are the official adjustments:

• Petrol 93 – Increase of R1.43 per litre
• Petrol 95 – Increase of R1.43 per litre
• Diesel 0.05% (wholesale) – Decrease of R3.25 per litre
• Diesel 0.005% (wholesale) – Decrease of R2.62 per litre
