Should I Try Ethanol?
I have a 2002 Suburban with the 5.3 Liter Flex Fuel engine (code Z). A station close to home is now selling E85 Ethanol. Today's price range is $2.59 for Unleaded and $2.29 for E85. Is the fuel mileage penalty greater than the $.30/gal I will save? (I usually get 13.5 to 14 MPG in town)
Are there any other idiosyncrasies associated with E85 that I need to be aware of?

The problem it ethanol don’t get the same mileage it burns more per mile. It’s cheaper but you loose a couple of miles per gallon so it evens out to pretty much no savings.

I tried a few tank fulls in my silverado. I was not happy with it. I didn't like the mileage I was getting. I lost about 4mpg with e85.

Are you over 21-and don't drink and drive!
Like everyone else said-ethanol has about 70% of the energy of gasoline(by volume), so 85% ethanol has about 75% of the energy of pure gasoline.I think a 30 cent discount is a rip off.It should be more like $2 even to make it a fair trade off.
No advantage-except to so big farmers- to use ethanol.
Biofuels that use food crops(except for maybe sugar cane-maybe) aren't really doing any good for the planet, and aren't decreasing net CO2 production(if that is a concern).
Once fuel can be made from something cheap to grow that can be grown on marginal land(land useless for growing anything else) then they will make sense. Maybe the algae grown from the CO2 from power plants will work out. Heck,I could buy myself a full on Duramax with no guilt at all (except for not having the $50,000 of course).
The ethanol is a decent enough additive for other reasons- but pointless now as a full fuel.Biofuels are a bust for now.

While I basically agree with those above, There is one exception to the rule. E85 is higher octane, thereby allowing you to run higher compression and/or more timing advance. With a stock engine, this doesn't make much difference. But with any sort of forced induction, this allows for a nice performance boost.1986 Chevy G20 Tow Rig - 5.7 TBI conversion

for 2 1/2 months i had a 2009 burb e85 rental, and what the difference in cost to miles per gallons
savings was i'd loose / even out averaging - in having to fill it up quicker.
no big thrill and i didnt help to save anymore dinosaur bones to make a difference...
if anything, i helped to increase the cost of corn products to the eating consumer who
has to buy corn to help feed the family...
yeah, i could stomp on the pedal while blasting onto a freeway enterance ramp and get a boost,
but it didnt help with actual driving changes....
overall i'd chalk that crap up to the greenpeacers' "the sky is falling !! " mentality to pusuade
congress to force the crap down our throats....:fighting0037:
when in doubt, doubletap !
