Weymouth

The cheapest unleaded in town currently starts near 162p per litre. The gap between the cheapest and most expensive unleaded in town is around 5p per litre at the moment.

The supermarket sites, including Morrisons and Sainsburys, tend to set the floor for prices here. 2 of the 7 local forecourts are supermarket-run, and the rest split between branded and independent operators.

The low end of the market has recently been held by Morrisons around Mercury Road. Forecourts on Dorchester Road and King Street carry much of the passing trade, and their prices often move first.

On average the town runs a touch over the South West England norm for unleaded. For diesel, expect an average of roughly 181p per litre locally.

The comparison covers stations up to roughly 8 km out, which keeps out-of-town supermarkets and bypass sites in the same view as the town centre. The cheapest station in Weymouth is not fixed; the low spot moves between forecourts through the week, so the current ordering matters more than habit.
