Flex Fuel...old question

I notice about 2 or 3 MPG less with it, but I only buy it when I have some bonus perks for the station here that sells it so I get it a good but cheaper, so it kinda works out. I get a tank full about once every 5000 miles to keep things cleaned up. So if its never had it, using it can clog things up if its never had it in there.
 
Was popular around here a few years back, saw lots of cars with the option. Couple pumps sold it. Now, I couldn't find it for sale if my life depended on it. Good on paper, but the real world application seems to be less than ideal.
 
Have the flex fuel option on my Ford Escape. On a trip to CA I burned one tankful and didn't notice any appreciable drop in MPG. Don't have the E85 available around here so don't use it now. We do have the 10 per cent gas in all but the high priced stuff.
 
We"ve had flex fuel vehicles for over a decade. Yes, mileage is lower because of less energy in the fuel, no eth supporter will deny that- it"s just reality. Our standard is that if eth is 40 cents or more cheaper than E10, we are money ahead using it. Highest spread I remember was about 90 cents cheaper. Yesterday it was exactly 40 at a nearby station.
 
With the price of regular gas so cheap is pretty well a dead thing in these parts. Regular gas here is 10% E and right no priced around $1.45.
 
I don't think you need to go whole hog. They used to say (when gas was more expensive), the most bang for the buck was a 30% blend. Don't know how it figures at today's prices. Not a lot of blender pumps around because they were too expensive for many stations to install them. Some people would blend themselves. A % of your gas tank filled with 10%, then the rest of your tank topped off with 85%. I used the blender pumps for awhile but they were soooo slow since they blended as they pumped so finally went back to 10% since I'm short on patience. This wasn't even an E85 vehicle. Had no problems running it.
 
E10 really doesn't make a big difference on vehicles, not compared to E85. I ran several tanks in my Grand Cherokee several different times, while testing city and highway. I didn't notice much difference for power in the city but the mileage dropped about 15%. On the highway I noticed a significant drop in power, it was having to downshift for hills that it never struggled on, and the economy drop was around 25%. The mostly highway miles economy went from 23 MPG to 17 MPG average over several tanks.
 
With E85 you can't use miles per gallon. You use cost per mile to get a true cost comparison.
 
E85 at one local station is 50 cents less than regular.
Regardless of the price of regular. Always 50 cents less.

Gas mileage is slightly less in the car, but being a car we
haven't noticed a loss of power. It does make the exhaust stink.
Every time we pull it in the garage we smell it for a while.
 
My Toyota van is not flex but I can use about 45% blend and lose 2-3MPG.

The last time I looked at the E85 pump, it said atleast "50%" ethonal. I guess it depends on the price of whatever goes into gas. It will clean fuel tanks and take off paint.

In Oklahoma City E85 was 10 cents higher than E10, don't think they were selling much of it.
 
I like to use it in my 6.2 gas f250, when I pull a trailer. The octain is higher (over 100). Computer bumps timing up. Seems to have more power. O local pump says at least 70% alcohol. Mileage is worse. Probably cost per mile about the same.
