EARLIER this month, RAC Fuel Watch data showed that the average gap between average petrol and diesel prices reached a record 20p. 

As of Wednesday October 12, drivers were paying an average of 163.13p for unleaded while diesel had climbed to nearly 184p (183.94p) – a difference of 20.35p a litre.

RAC fuel spokesperson Simon Williams said: “Since OPEC and its allies agreed to reduce oil supply substantially, we’ve seen the price of wholesale diesel go up by 9p a litre and petrol by 4p a litre.

“This has led to the average price of diesel going up by almost 4p a litre and petrol by nearly a penny.

“Sadly, for diesel drivers, the situation seems certain to get worse with prices heading back to 190p a litre which will add £3 to the cost of a tank (£104.5)," he said.
