Thumbs down Ethanol in Fiesta

I thought I would give ethanol a go in my Fiesta.
BIG mistake!!
It normally drops a bar on the fuel gauge, around 90km's. With ethanol fuel it was 77km!!!
Back to PULP.

That drop of the first bar is not accurate though.... yesterday i put fuel in (but didnt fill it up)... it had 1 bar less then an indicated full. After a day of driving, i was leaving subway and it said it was full.......odd

I usually get 320km's to the half way mark. On ethanol it was 240km's. So, no more ethanol.

ethanol will use more than petrol, i think its around 10% which kills the supposed savings..

I filled up yesterday, and for the first bar with a mix of city and highway driving i got 96kms which is pretty darn good i think.
when i got onto the highway though it was like my car wasnt even turned on, airfilter and exhaust really help with economy, especially if your sitting on a constant 3- 3.5 thousand rpm

I thought ethanol was corrosive? Toluene is the other stuff I was thinking of thats bad for engines...

Ethanol is an octane booster, so did U see any increase in performance?

another misconception that people have is that octane boost = boost in performance.

this is wrong

when you increase the octane rating, you increase its resistance to combustion.

the only time you'll see some "increase" in performance is when performance is down due to detonation.

however, different fuels have different specific energy rating, which is what gives you your extra oomph when youre driving.

I read somewhere that it is pointless to put Higher octane fuel into a lower octane engine...
e.g. Putting 98 octane into my 95 octane rated zetec...

Can someone tell me if this is true or not?? and maybe explain why..

you'll find that stuff like optimax blah blah blah has higher specific energies than std fuel

and if you look at the wikipedia thingy, you'll see that although ethanol has a much higher octane rating, its specific energy is lower than normal fuel

this is why your fuel economy suffers the more ethanol you put in your car

Fiesta is recommended 95+.... and i do notice a slight difference with using the 98 octane.... the car is less thrashy at higher rpm > not struggling as much.
