From 650+ km/tank to 460km

Seriously man, im not kidding.

I was ecstatic with the thoughts of running ethanol free gas. Expected clearly visible, near earth shattering improvements. Not.

All I can say is, with my mpg logged with each and every one of 297 consecutive fill-ups since I took ownership of my car, the instances where ethanol free were used did not differ from fuel with ethanol added.

Power should only be 'necessary' during take-off and hill climbing. Once the vehicle is rolling, you essentially only need enough to maintain momentum. At this point, the lower power in ethanol gas would be negligable in its impact on f/e.

This doesn't apply to everyone

I also tried Ethanol free gas in my Yaris. The conclusion .. there was NO difference in fuel economy detected. The only place I noticed a difference was my wallet as it was more expensive.

That's not the way it works.

When ethanol is substituted into the fuel, it reduces the amount of energy in the fuel - so there's less energy in the fuel.
That translates into less energy per unit volume in the fuel and less overall energy in the entire tank of gas.
You *should* see a difference in gas consumption.

I know I drop down from ~500km per tank (40L fillup) to ~450km per tank once winter fuel starts getting supplied at the pumps.
