I have to dissagree. I have run E10 (95 Octane) in my onld camary and Auion for years. I cant see much difference at all, it may the the crappy petrol stations you go to, not sure. 95 Octane Premium (real fuel) does give a little better consumption, but for 8 cents cheaper a litre, I'll keep running the E10. I know may will never agree. I would prefer to run Premium all the time too.
