I made the switch to real gasoline in April. We have about ten gas stations in Mid GA that sell gas without the ethanol blend. Since then, my Prius has shown increased pep and MPG. I also run pure gas in my wife's Avalon and it too has performed with better MPG/power in the pedal. I've talked with Toyota master techs here and they tell me Ethanol is horrible for the intake. Got to see proof in their shop with some fuel issues. Curious if anyone else has run real gas in their Prius and what they've noticed.
