Perth timing
In Perth, Wednesday was the lowest day in 11 of 11 recent full weeks. This comes from full weeks over the last 90 days, not a fixed rule. Check the price cycle before a full tank, and confirm reported prices and update times on the Perth fuel prices.
When Perth is near a cycle low, fill the tank rather than topping up, so your next purchase lands past the next reset. Right after a sharp reset, buy only enough to get through, then check again as prices ease. When the spread between stations is wide, pair the timing with a cheaper suburb on the Perth fuel prices to compound the saving.
