Latest confirmed diesel price by effective date
Diesel is used across transport, logistics, commercial operations and electricity generation, so changes in the official pump price can have broad cost implications. Salone Fuel Monitor displays the latest confirmed positive diesel value in the official price timeline together with its effective date.
A blank or zero diesel entry is treated as no diesel price recorded for that price event. It is not interpreted as free fuel and it does not replace the most recent confirmed diesel price on this dedicated page.
Use diesel history to understand changes
Recent diesel-price records help users distinguish a one-off announcement from a wider trend. The Fuel Price History page provides the full effective-date sequence for petrol, diesel and kerosene, while the transport-fare and market-intelligence pages provide additional context for how fuel-cost changes can affect businesses and mobility.
Regional comparisons can also show how Sierra Leone diesel prices sit alongside selected West African markets. Those comparisons should be read with their dates, exchange-rate assumptions and country-specific pricing systems in mind.
