THE petrol price will drop by 13 cents to the litre on Wednesday, further easing consumer worries raised by a 30% petrol increase over the best part of last year. Diesel will drop by 16 cents to the litre while illuminating paraffin drops by 25 cents, offering hope for millions of users ahead of the upcoming winter months. The prices cuts are mainly due to the drop in the price of crude oil stemming from oil cartel Opecs decision to cut output to keep prices at $25 a barrel.
