Diesel users in South Africa will keep their full fuel levy relief in May 2026, with the General Fuel Levy on diesel effectively reduced to zero through a R3.93 per litre rebate. The diesel fuel levy May 2026 relief was extended by Finance Minister Enoch Godongwana ahead of the 6 May fuel price adjustment, while petrol drivers face a price hike of around R2 per litre.

What the May 2026 diesel relief looks like
The diesel relief in May 2026 keeps an enhanced rebate of R3.93 per litre in place, which fully offsets the standard General Fuel Levy on diesel. Petrol drivers also keep a R3 per litre relief on the General Fuel Levy, but a sharp rise in the basic fuel price still pushes the pump price for 95 unleaded up by around R2 per litre from 6 May. Coastal motorists are looking at roughly R24 per litre and inland motorists at over R25 per litre.
The relief was first introduced on 1 April 2026 and was due to expire on 5 May. Treasury extended it after fresh upward pressure on global oil prices linked to disruption in the Strait of Hormuz and a weaker rand. Without the extension, diesel would have risen by close to R5 per litre.
How the General Fuel Levy works
The General Fuel Levy is a national tax built into every litre of petrol and diesel sold in South Africa. It funds the national fiscus and is separate from the Road Accident Fund levy and the basic fuel price. By zeroing the diesel General Fuel Levy through a rebate, Treasury is shielding logistics and agriculture from the worst of the May spike without removing the levy permanently.
Who benefits most from the diesel fuel levy May 2026 relief
The relief flows to anyone who buys diesel at the pump. Long-haul road freight, taxi operators on diesel fleets, commercial farms running tractors and harvesters, generator-dependent businesses and the mining sector all benefit. Households running diesel bakkies get smaller direct savings but benefit indirectly from contained food and transport costs.
SARS also extended its enhanced diesel refund for qualifying primary producers in mining, farming, forestry and fisheries. Eligible operators can claim back the levy portion of diesel used in qualifying activities through the diesel refund system.
What to expect from the petrol price on 6 May
The Department of Mineral and Petroleum Resources confirmed the new fuel prices apply from midnight on 5 May, with pumps reflecting the change on 6 May. Petrol 95 rises by around R2 per litre and petrol 93 by around R1.73 per litre. Diesel users see a small adjustment of a few cents, thanks to the extended R3.93 rebate. Illuminating paraffin also rises sharply, by over R5 per litre, which will hit lower-income households hardest.
Frequently asked questions
Is the diesel fuel levy zero for all diesel users in May 2026?
The General Fuel Levy on diesel is effectively zeroed for the May pricing period through a R3.93 per litre rebate. Other components, including the Road Accident Fund levy, customs duties and wholesale margins, still apply.
How long will the diesel relief stay in place?
Treasury has confirmed the relief for May 2026. A further extension into June will depend on the Brent crude trajectory, the rand and the under-recovery position closer to the next monthly fuel price adjustment.
Why is petrol going up while diesel relief is extended?
Government opted to spend the limited relief budget on diesel because diesel cost shocks feed directly into food prices, freight tariffs and farming inputs. Petrol relief is in place but at a lower R3 per litre rate, which the May basic fuel price spike is now overwhelming.
