Petrol and diesel prices will be hiked on Wednesday, with oil having become more expensive due to stronger Chinese demand. Unleaded petrol (both 93 and 95) will increase by 28c a litre, while diesel will be hiked by between less than a cent and around 9c a litre. Paraffin will increase by 58c a litre, and the maximum retail price of LP gas will fall by R1.40 a kilogram. The latest price hikes will push Gauteng petrol to R21.68 a litre, from R20.14 a year ago. Petrol peaked at R26.74 in July this year. Gauteng diesel will climb to as much as R21.32 a litre, from R18.04 in February 2022. Diesel was close to R25.50 in November last year. The fuel prices are usually adjusted on the first Wednesday of a month and determined by the price of international oil and fuel prices and the rand-dollar exchange rate.
