98 octane petrol prices in Australia
Premium 98 is the highest octane petrol sold at most Australian service stations. It is aimed at high-performance and turbocharged engines, and it is usually the most expensive petrol on the board.
The board shows each capital city's average and lowest 98 octane price, whether the figure is live or an estimate, and when it was updated. Use the cost box to see what a few cents per litre means on a fill, then compare with the 95 and 91 boards before you decide.

Frequently asked questions
Do I need 98 octane petrol?
Only if your manufacturer requires or recommends it. Some high-performance and turbocharged engines are built for 98. If your owner's manual allows 91 or 95, 98 is optional.
What does 98 mean at the pump?
It is the Research Octane Number (RON). A higher octane fuel resists engine knock better, which matters for engines with high compression or turbocharging.
Which city has the cheapest 98 petrol?
It changes day to day. The table is sorted by average price so the cheapest capital city is at the top, and each city page has its own fuel calculator.
Where does this 98 octane price data come from?
From official state fuel price schemes where available (Victoria, Queensland, Western Australia, South Australia, and NSW and ACT). Each row is labelled live or estimate, with a last-updated time.
