The holiday has already begun for many, and will have to pay more for petrol and less for diesel from Wednesday.
Petrol increases by R0-11 per liter for 93 as well as for 95 degrees, but diesel decreases in price by R0-18 and paraffin decreases by Ro-21 for December month.
Economic experts say the rise in gasoline prices, and the slight drop in diesel and paraffin prices, could be attributed to the weak Rand, which just failed to return to its levels two years ago.
