Ethanol

In my newer Honda CRV, I noticed a large difference between the mileage depending on where I bought fuel. 1 liter per 100 km difference. Turns out it is the difference between real gasoline and ethanol blend. The chemistry is right, the power is just not in ethanol. Ethanol fuel is costing me $1.15 more per 100 km. It also uses slightly less oxygen, and puts out co2 and more nitrogen combined produces as it burn hotter, but with less expansion. So much for economy, and the green movement, sustainability, and the government bull shit.
