How to read the current petrol price
Salone Fuel Monitor treats the effective date as the authoritative date for a national petrol-price record. The latest displayed petrol price is therefore the most recent confirmed positive petrol value in the official price timeline, not simply the newest document when that document contains no petrol value.
This matters when different fuels are updated independently. A record can contain a new diesel or kerosene price while petrol is blank. In that case, the petrol page continues to identify the latest confirmed petrol price and shows the date on which that petrol value became effective.
