Years ago when ethanol started I never thought much about it. But when I did a long highway trip in my 1990 Suburban the milage dropped by 10%. Since I've had this truck a long time I was familar with it and milage etc... so I went looking for maintence issues (all logged in a book) nothing was due or overdue so I looked more and never found an issue.

Next highway trip I checked and milage was back up? So I wrote it off as a bad day, head wind, whatever. It was about a year later I learned of the effects of ethanol blends.

yeah, it's a pretty slippery slope adding alcohol to fuel...

since it has a rather high octane rating, but less energy per gallon(and a lower stoich AFR) compared to gasoline, it allows you to mix lower octane gasoline with it to get up to whatever octane you need at the expense of how far you can travel.

somewhat of an advantage is that so far, ethanol is a bit cheaper than E0 gas, so it lowers fuel prices a little bit... however, more often than not, it lowers fuel economy by a larger margin than the price drop.
