diesel vs petrol price melbourne

In Melbourne, petrol (ULP 91) is usually cheaper per litre than diesel, but it yo-yos with the city’s infamous price cycle, while diesel plods along more steadily.

Expect the petrol cycle to swing by roughly 20–40 cents, so one week it’s a bargain, the next it’s acting like it owns Toorak; diesel is often 10–30 cents dearer than 91 but not as moody.

• Petrol: lower pump price most days, big discount windows during the dip, but thirstier in many cars.
• Diesel: typically pricier per litre, steadier prices, better economy on long runs (and tow-friendly), but mind DPFs and AdBlue.

If you’re chasing the cheapest fill, time petrol buys for the downslope of the cycle; if you value predictability, diesel’s the calmer tea. For live numbers, use local fuel apps and keep an eye on nearby suburbs—the gap can change street to street.
