Esso in King Street, Weymouth, ran out of unleaded petrol on Wednesday afternoon and diesel on Thursday morning. Staff said they were hoping to get a delivery soon.
The Esso garage at Lanehouse Rocks Road shut the forecourt for a couple of hours to allow a delivery tanker to get in.

The Esso garage on Granby Industrial Estate was closed in the afternoon and the forecourt coned off.
In Dorchester motorists queued down Weymouth Avenue. A spokesman said: “Unleaded fuel ran out yesterday morning and the garage only has diesel.”

“We’re ok for fuel – but we’re running out so we’re just limiting the amount people fill up.
