I have a 2012 Prius Hybrid, and in the manual it recommends 95 octane, however it can take e10. As Premium 95 octane is about 10c/l more expensive than 91 regular unleaded, I would ideally like to find an e10 that's 95 octane, but can't (I'm in Qld). Woollies E10 is 91, and Coles e10 might be 93 but can't confirm this. Anyone help with this? I read that when you add ethanol to petrl it raises the octane level, so that means Woolies must have been below 91 octane before they added the ethanol. PS. What is the recommended fuel for the Camry hybrid, and if it's different, why?
