1987 Toyota Xtra Cab SR5 4x4 with EFI. 24.2 MPG lifetime average on true gas. 21.8 MPG when E10 arrived everywhere. I know my numbers are correct and fact, as I logged every single fillup, gallons bought, miles traveled, topped off and brimmed to the neck, each and every fillup. E10 sucked... nothing but filler waste, doing nothing but taking away 10% of your MPG's. I hated the stuff, made my fillups more frequent and more expensive.
Ethanol is fluff in your fuel tank, a large percentage of alcohol is, by weight, oxygen. Why would you want to carry around oxygen, when you can get it free for ignition from the air intake? Therein lies the fallacy. Splitting hydrocarbons and taking free oxygen from the air makes energy. Providing oxygen in the fuel is just plain stupid, from a chemical reaction point of view. It adds expense, while not providing energy to propel you forward. Dumb, really, really dumb.
