Finding the price inside an official decision
Open a fuel-price decision and you may find several amounts, more than one date and a page of administrative wording. The number you need is attached to a particular product and an effective clause. Once you have those details, most of the apparent complexity falls away: you can say which price applies, from when, and where the statement can be checked.
For FuelAzores, one approved official source is enough when it clearly establishes the exact price and effective date for the correct fuel and unit. There is no need to wait for a newspaper to repeat the announcement. Conflicting official claims or unclear wording still need review. This approach puts the document's content first, rather than treating the number of websites carrying a story as a measure of accuracy.
You do not need to read every item in a journal issue to check a refill. Find the relevant act, read the full price clause, then locate the sentence saying when it takes effect. Keep the link with your note. The same approach works when checking an old receipt, querying an app notification or trying to understand why two pages appear to show different prices.
A price decision, a tax measure or a formula amendment?
For the Azores, look for the relevant act in the Jornal Oficial dos Açores or an approved official reproduction such as the Diário da República record. For Madeira, look in JORAM, including its supplements. The regional identity must be established by the act itself. A website navigation menu mentioning Madeira does not turn an unrelated article into a Madeira pricing decision.
Distinguish a retail-price decision from a formula amendment, tax ordinance, support scheme, or statistical report. Each can mention fuel and contain euro amounts, yet answer a different question. A tax measure might explain an input to the final price without setting that week's maximum. A support payment to an eligible business might affect its costs without changing the retail amount available to an ordinary driver.
Two useful examples are the Azores September 2026 pricing decision and Madeira Joint Order 82/2026. They contain explicit maximum-price clauses and effective dates. By contrast, Madeira Ordinance 166/2026 changes the formula. It is relevant evidence about the system, but it is not a substitute for a particular week's retail table.
Check the publisher and the act number
Open the original publication or official reproduction and inspect the title, act number, year, issuing authorities, and journal information. A filename is a useful clue, but the document's content should confirm its identity. A copied PDF on an unrelated website may help locate the source; it should not automatically inherit official status from a logo visible on its first page.
For an official reproduction, preserve the identity of the underlying act. The same Azores decision appearing in two official locations is still one decision, not evidence of two separate votes or announcements. Recording the act number and publication details makes this relationship clear. It also helps distinguish a later amendment or correction from another copy of the original text.
If a link redirects or the publication cannot be accessed, do not fill the gap with a search snippet and call the extraction complete. Retain the last verified information with its date, or show that the new candidate needs checking. A failed retrieval is a technical observation about access, not proof that the government published nothing or that an existing price changed.
Read the fuel label before the amount
Official texts can place several products in adjacent clauses. Read the full label associated with each amount, including the petrol octane rating or the specified diesel use. In a PDF, line wrapping can place the amount far from its label. A text extractor may also flatten columns so that the nearest number is not the number belonging to the product you intended to select.
Road diesel must remain distinct from coloured and marked diesel or activity-specific categories. Bottled gas, bulk gas, and liquid road fuels may appear in one publication but have different units and conditions. A category should not be collapsed into another merely because two amounts happen to match in one period. The identity needs to remain stable when the values later diverge.
When the wording is ambiguous, review the page visually and inspect the surrounding clauses. Do not solve uncertainty by selecting the lowest number or the category that seems most familiar. The aim is a faithful extraction, not a prediction of what the table ought to contain. The price can only be confirmed once the association between product and amount is clear.
Reading 1,921 euros per litre correctly
The unit is not a cosmetic label. Euros per litre, euros per kilogram, and euros per thousand litres cannot be substituted without explanation. A petroleum-tax rate per thousand litres is not the retail price for a litre. A bottled-gas figure per kilogram is not the total price of a particular cylinder unless its applicable content and conditions are also known.
Portuguese publications commonly use a decimal comma. An amount written as 1,921 euros per litre corresponds to €1.921 per litre in English notation. It does not mean one thousand nine hundred and twenty-one euros. Preserve all three decimal places when the source provides them. Translation should change the notation for the reader while retaining the exact numerical value and unit.
Be wary of shortened news amounts such as approximately €1.92. They may be perfectly adequate for a casual summary but cannot establish whether the official amount was €1.921, €1.924, or something else. Do not infer an exact three-decimal price by adding a zero to a rounded report. Exactness belongs to the source claim, not to the number of decimals a website chooses to display.
Signed, published and in force: three different dates
An act can have a signing date, publication date, effective date, and retrieval date. Each answers a different question. Signing relates to the act's formal execution; publication identifies its appearance in the journal; effectiveness determines when the price applies; retrieval records when a service accessed the evidence. A reliable record should not use one field as a silent substitute for another.
In the Azores example, publication was on 26 August 2026 and the price clause took effect on 1 September. In the Madeira example, the document was signed and published on 4 September, with prices applying from 7 September. The differences are ordinary consequences of announcing a future period. They should not be interpreted as conflicting dates until the meaning of each has been identified.
Read time in the relevant region. An effective clause stating midnight concerns the start of the named day in its applicable local context, rather than whichever timezone happens to be configured on a reader's device. Preserve exceptional dates or hours explicitly stated by the document. The routine weekly or monthly cycle is background knowledge, not permission to overwrite the actual clause.
Record the Madeira diesel example
Take the Madeira road-diesel example effective 7 September 2026. A useful record includes Madeira as the region, road diesel as the category, 1.951 as the exact euro amount per litre, the effective time stated in the order, Joint Order 82/2026 as the act identity, and the link to its JORAM supplement. None of those fields is interchangeable with the page's last-accessed date.
| Record field | What to preserve |
|---|---|
| Source identity | Official publisher, act number, year, and original link |
| Product | Full category sufficient to distinguish similar fuels |
| Amount | Exact value, currency, unit, and source precision |
| Timing | Publication date and separately stated effective date |
| Interpretation | Any uncertainty, correction, or conflict requiring review |
You can keep these fields in an ordinary spreadsheet or a short note beside a saved document. Later, if someone asks where €1.951 came from, you can point to the precise fuel and period instead of searching again. Put your own calculations in another column: forty litres at that maximum gives €78.04, but the order did not publish a separate quotation for your tank.
When a correction changes an earlier figure
When an official correction or later act changes an earlier claim, read its scope carefully. It may correct a product, amount, date, or another part of the text. Do not assume that every field changed, and do not continue presenting the original extraction as unqualified current evidence. Preserve the relationship so that the history explains why a number was replaced.
If two official claims genuinely conflict and the relationship is unclear, the conflict needs review. A majority of newspaper reports cannot resolve it by vote. Likewise, a newer publication timestamp alone does not prove that a document supersedes every older price. Check the act's subject, effective clause, amendment wording, and any express revocation or correction before selecting which claim applies.
A newspaper may use another fuel category, round the figure or discuss the following week. Check those possibilities when its number differs from a clear official price. If the report is simply wrong, the valid official amount still stands. If the report points to another official act, open that act and compare its scope and dates. The useful lead is the document it identifies, rather than the newspaper's agreement or disagreement by itself.
Is the price current, upcoming or historical?
A current price is one already applicable at the time being considered. An upcoming price has official support but an effective time still in the future. A historical price belongs to an earlier period. All three can be valid at once, provided their labels and dates are clear. Publishing an upcoming amount should not prematurely erase the currently applicable price from a reader's decision.
A notification about an announced change should make the effective date easy to see. Someone reading it several days later needs enough context to understand whether the change is still upcoming or already applies. The same principle holds when a message is forwarded or a screenshot circulates without its original timestamp. Relative phrases such as next Monday are less durable than an explicit calendar date.
When reviewing history, order records by applicability rather than retrieval. An old decision discovered today still belongs to its original effective period. Importing it should not make it the current price merely because it is the newest database entry. The comparison guide explains why this distinction matters when aligning different regional calendars.
What to do when information is missing
Pin down what is missing before looking for more material. Is the PDF unavailable, the fuel label cut off, the price rounded, or the effective date absent? Each problem calls for a different next step. Opening the original page can resolve a broken text extraction; reading the final clause can resolve a date question. Finding another copy of the same rounded headline will not recover a missing third decimal.
Do not fill a missing historical interval with zero, interpolate an official amount, or assume that a regular update schedule proves a change happened. If continued applicability is known, describe it; if it is not, preserve the gap. A dataset can be useful with explicit limitations. It becomes misleading when incomplete evidence is hidden behind a complete-looking chart or a confident current-price label.
If you are about to buy fuel, read the latest verified applicable information and confirm the displayed price at the station. If you are checking a historical question, save the incomplete record with a note describing the gap. Those are different tasks with different deadlines. A document that cannot be retrieved today may become accessible later, but its contents should not be filled in from memory in the meantime.
Write the full claim before forwarding it
Before forwarding a price, try writing a complete sentence: the named fuel has a maximum of the stated euros per litre in the named region from the specified date, according to the linked act. If you cannot finish that sentence from the document, find the missing detail first. Keep any refill total in a second sentence so the reader can distinguish the official amount from your multiplication.
For a query to FuelAzores, include the region, fuel, date and price that prompted it, with the relevant official link or receipt. The Help page opens a route to support, and the app guide explains where to find price details. There is no need to diagnose the software yourself. A complete example lets the issue be checked against the original record.
Frequently asked questions
Is one official source enough?
Yes. One approved authentic official source with the exact amount and effective date is sufficient when the fuel, unit, and meaning are clear. Review remains necessary for official conflicts, ambiguity, authenticity concerns, and category or date problems.
Can a search result prove the exact price?
Use search results to discover documents. Verify the amount and effective date in the actual official content. Summaries can omit context or round figures, so they should not supply an exact claim merely because they link to an official domain.
Does a formula amendment establish today's pump maximum?
It establishes the rule change described in the act. A particular retail maximum still needs the relevant price decision or another approved official source explicitly providing that exact amount and effective date. Keep the formula and the resulting price record separate.
