Motorists should expect petrol prices to drop in the coming weeks according to a marine trade analyst who on Thursday (December 11) said that it takes a while for a drop in crude oil prices to be passed on to consumers.

Oil edged higher on Thursday towards $65 a barrel helped by a weaker U.S. dollar, although prices remained close to a five-year low on signs that already ample supply will be even more plentiful in 2015.

Motorists at a petrol station in London said they hadn't yet noticed a significant drop in fuel prices as a result.
