South African petrol prices are projected to fall by between R1.74 and R2.04 a litre in December 2026, according to TopAuto’s forecast. The estimates already account for a reduction in temporary fuel levy relief.
Diesel is moving in the opposite direction. The outlook points to small increases, although the supplied forecasts do not give a figure for either diesel grade.
Projected Inland Petrol Prices For December 2026
| Petrol grade | November price | Projected decrease | Estimated December price |
|---|---|---|---|
| Petrol 93 | R29.87/litre | R1.74/litre | R28.13/litre |
| Petrol 95 | R30.24/litre | R2.04/litre | R28.20/litre |
These are inland estimates. The final December adjustment has not been confirmed in the supplied material.
Lower Oil Prices And A Stronger Rand Support Petrol Cuts
Lower Brent crude oil prices and a firmer rand against the US dollar have eased pressure on fuel import costs. Together, these factors support a projected petrol price cut even as National Treasury scales back its temporary General Fuel Levy relief.
Petrol levy relief drops from R1.50 to R1.00 a litre, adding 50 cents a litre back to the levy. The projected decreases of R1.74 and R2.04 already include this change.
Diesel Prices Are Expected To Rise Slightly
Diesel has a smaller gap between its current price and the cost of supplying it. According to the BusinessTech outlook, those savings are expected to be outweighed by a R1.50-a-litre reduction in diesel levy relief, leaving diesel on course for a small increase.
