Motorists can breathe a sigh of relief as both grades of fuel - 93 and 95, will decrease by 13c a litre from Wednesday this week. Diesel prices will be cut by 16c (0.05% sulphur) and 14c (0.005% sulphur) respectively. In October the price of petrol rose by between 18c and 4c a litre, while in September both grades of petrol rose by 11 cents. The decrease is largely thanks to a stronger rand during the past month.
