What the fuel cycle is
The Melbourne fuel cycle is a repeated pattern where many retailers discount fuel over time, then lift prices sharply when a reset begins. The cycle is not a rule or guarantee; it is a retail pricing behaviour visible across many stations.
Drivers notice the cycle because the difference between peak and low prices can be large enough to change the cost of a full tank.
Why prices spike
A spike usually reflects retail repricing, not necessarily an immediate change in wholesale fuel cost. Some stations reset first, while others hold lower prices for longer.
This staggered movement creates comparison opportunities. During a reset, nearby stations may show very different prices for the same fuel grade.
How to use the cycle
When the cycle is near a low, filling sooner can reduce the risk of buying after a reset. When prices have just jumped, compare nearby stations before assuming every outlet has moved.
The cycle should guide timing, but live station prices should make the final decision.
Quick answers
How long is the Melbourne petrol cycle?
The length changes. Melbourne cycles can vary from a couple of weeks to more than a month, so current price checks are more useful than a fixed calendar rule.
Do all brands move at the same time?
No. Different brands and stations can reset at different times, which is why local comparison can still find cheaper options.
