MyFuel helps you see more than the total you have paid: it also shows what makes up your recorded spending. You can assign a category when recording another car expense or organise an older entry that has no category. Fill-ups are grouped automatically. Fuel is not a category you can select in the form for another expense.

Choose a category for a new expense

  1. When entering another car expense, choose a suitable group in the “Category” field.
  2. Save the record.

The category will help you distinguish what you paid for later. For example, you can place a recorded financing payment under “Lease / loan”. Choose based on the payment itself so expenses of the same kind are easier to compare when you review them.

For a new expense, a recognised keyword in its description may produce a “Suggested: {category}” prompt. If the suggestion fits, press “Apply”, check the chosen category, and then save the expense. The suggestion is an optional keyword match, not AI or information read from a receipt photo. It may not appear at all, and applying it does not save the expense by itself. Do not expect this suggestion while editing an older entry.

Organise an older expense in the journal

If you previously recorded an expense without a category, open the “Journal” and select “Add category” on that entry. Choosing a category in this quick picker starts saving immediately; there is no additional save button. Wait until the app confirms success, particularly on a slow connection. If an expense already has a category and you want to change it, open and edit the expense instead.

Review spending by category

  1. Open “Total” in the overview.
  2. Tap a category under “Spending by category”. The “Journal” opens with that category already selected as a filter.
  3. There you can change the displayed time using “Period”, for example to “This month”.

“All categories” expands the list in the overview; it is not a category dropdown in the journal. In the journal, “Show all categories” clears the category filter. Switching the overview between fuel, expenses and total spending also clears it.

“Uncategorised” means that no category has yet been assigned to another expense. The expense still counts towards recorded spending. This differs from deliberately selecting the catch-all category for a payment that does not fit a more specific group. Reviewing older uncategorised records can make the breakdown more useful without changing what you actually paid.

These totals cover payments you recorded, not every cost of owning a car. Payments you did not enter and future expenses will not appear here. If you are planning a future drive, use the separate trip fuel cost guide. For an introduction to the app, visit the MyFuel walkthrough; you can find other guides in the article index.
