This all comes with the latest wholesale price for the fuels, which are purchased by the garages and then sold on with duty and other taxes costed in to the total price.
And while those garages were the most expensive, at the other end of the scale, Whiteway Motors was selling Diesel at 126p a litre and Unleaded at 124p.
Northern Motor Works, Le Mont Saint and La Villette were also amongst the cheapest in the last week.

The wholesale increase was announced toward the end of last month – and comes from the fuel suppliers, while fuel duty is decided by the States of Guernsey.
Guernsey Road Fuel Duty was increased to 67p a litre in October 2017, and accompanies prices which have been steadily increasing for a number of years now – prices themselves are updated at retailers on a weekly basis.
Currently, according to a recent survey in Jersey, unleaded prices go as 102p per litre, with an upper bound of 113.9p.
