How to use the cycle
Time your fill-up in Adelaide
The weekday rule is only a starting point. What matters is where the Adelaide market sits in its cycle.
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.
Combine timing with suburb choice
When the spread is wide, pair the best buy day with a cheaper suburb on the Adelaide city page to compound the saving.
