Hiro is right - I have tested the different fuels, driving the same route daily. Minus the traffic, I found that I had to fill up more often with E10 than with 95 and 98. Between 95/98 you won't feel the difference much at all with a Camry - economy wise still the same give or take. On the other side as well, E10 and 91 are almost the same, 1% difference in ethanol/petrol whichever way you look at it. -- My average has been 14L/100kms lately - I guess more cause I'm having too much fun with my new exhaust haha. Normally get around 12L/100KMs - mostly city driving. I know with your Camry Hybrid 2013 you can play with the Eco and Normal mode as well.
