The Department of Energy has announced a petrol price increase of 54 cents a litre for 93 and 95 unleaded for the month of May.
Diesel has a one cent per litre increase, while illuminating paraffin sees a three cents per litre increase.
In a statement the Department of Energy said the international factors amounted to about 54.00c/l on petrol and 1.00c/l on diesel and 3.00 cents per litre for illuminating paraffin.
"The settling of contagion risks from emerging markets provided a foundation for the rand's strengthening trend. This decreased the contribution on the Basic Fuel Price of petrol, diesel and illuminating paraffin by about 13.00c/l," the statement said.
