Drivers have been issued a warning by the RAC if they are planing to visit a petrol station this week.
It comes as prices are set to rise again, with retailers having failed to fully reflect the fall in wholesale prices, according to the RAC. The automotive services company warned wholesale diesel costs have plunged 32p per litre - but the pump price has only fallen by 20p in the same period.
The cost of petrol has dropped by 23p in the same period, however at the stations, the prices have only been reduced by 18p meaning those behind the wheel are paying over the odds, the experts say.
