How to use the cycle

Time your fill-up in Perth

The cheapest weekday can change. Check where the Perth market sits in its cycle before you fill.

  1. Fill fully near the low

    When Perth is near a cycle low, fill the tank rather than topping up. The point of timing is to push out your next purchase past the next reset.

  2. Top up only after a reset

    Right after a sharp reset, a full fill-up is usually poor value unless you urgently need it. Buy only enough to get through, then check again as prices ease.

  3. Combine timing with suburb choice

    When the spread is wide, pair the best buy day with a cheaper suburb on the Perth city page to compound the saving.
