Premium 98, ULP98 and 98 RON explained
Premium 98, ULP98, P98 and 98 RON all refer to premium unleaded petrol with an octane rating of 98. NSW FuelCheck classifies Premium 98 this way; RON describes resistance to engine knock, not a guaranteed increase in power or fuel economy.
Check the minimum RON in your owner's handbook or on the fuel-filler flap. RACQ advises against using a lower octane than specified and notes that the benefit of a higher grade varies by engine. See the NSW FuelCheck fuel definitions and RACQ high-octane guidance.

Frequently Asked Questions
What is Premium 98 fuel?
Premium 98 is premium unleaded petrol with a Research Octane Number (RON) of 98. It is also labelled ULP98, P98, 98 RON or 98-octane petrol at Australian service stations.
Is Premium 98 the same as ULP98 and 98 RON?
Yes. Premium 98, ULP98 and 98 RON are common names for the same petrol grade. RON describes the fuel’s resistance to engine knock; it is not a measure of how much energy the fuel contains.
Does my car need 98 RON fuel?
Use the minimum octane rating stated in your owner’s handbook or on the fuel-filler flap. Some performance vehicles specify 98 RON, while many vehicles specify 91 or 95. Do not use a lower octane than the manufacturer requires.
Is 98 fuel better than 95?
98 RON is more resistant to engine knock than 95 RON, but that does not guarantee better economy or performance in every car. If your vehicle requires 98, use 98. If it specifies 95, any benefit from paying for 98 depends on the engine and may not offset the higher pump price.
