Aussie Fuel types RON/OCT

Austins · 11-21-2018, 01:51 PM

Hey guys, hopefully not gonna sound stupid here haha

I swear we, in Aus, used RON rating for fuel...
but here i am on the United & BP websites and they're all saying 98 octane, not 98RON...

I've been running the 98RON/93octane MHD map under the impression that we used RON...
Then people say in aus Octane rating on pumps is '98RON'... dafaq, is MHD messing with my head with OCT/RON haha

Can someone clear this up please haha

'Premium 98 is a high performance unleaded fuel with an octane rating of 98'

https://www.bp.com/en_au/australia/p...-unleaded.html
'BP Ultimate Unleaded is our most advanced petrol with a minimum octane number of 98'

Octane is measured in a few different ways.

Australia uses Ron
Usa uses mon

98 Ron = 93 Mon

RON (Research Octane Number) is used in Australian fuel standards. Those websites are .au domains and are using RON.

MON (Motor Octane Number) is determined using a different testing method.

AKI (Anti Knock Index) or PON (Pump Octane Number) is used in North America. It is derived mathematically (RON + MON)/2
eg. RON 98 + MON 88 /2 = AKI 93

Thanks for clearing it up!
