This is reflected by a surge in the price of oil to around $40 per barrel as demand increases post-lockdown.
However, despite the surge in wholesale costs, average pump prices rose only marginally to 108p per litre this week.
This is because many supermarkets have pledged to keep prices at under £1 per litre through the rest of locks down to help their customers.
Non supermarket retailers doubled their margins from pre lockdown levels of 9p per litre to 18p in the first part of April.
The AA says as supermarkets ease the pressure by increasing pump costs, non supermarket forecourts may join them to cling on to extra profits.
