About Unleaded 91
Unleaded 91 (U91) is standard regular unleaded petrol — 91 octane (RON), the baseline fuel sold at virtually every Australian servo. It suits most cars built before about 2008 and is what your owner's manual usually means by "regular unleaded". U91 is typically the second-cheapest grade after E10 and runs a 2-5 week price cycle in capital cities.
