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.

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.
