Ethanol Free gas and the EcoBoost
who is that?

my experience was that the gains were neglible at best, and perhaps not even there.
ethanol has 85% of the energy of gasoline - and is only blended at 10%
so, you have .1 x .85 + .9 = .985
this means that E10 has 98.5% of the energy of 100% gasoline. so we should see a decrease in mileage due to the lower energy level ~1.5%. These claims of a 30% increase in mileage (28.8mpg / 22.2mpg) are unrealistic in my opinion - no way you will see that gain from a fuel source that contains 1.5% more energy per volume.

ETOH is for drinking, cooking, and cleaning, not driving. I can't believe this country government got lobbied by those damn corn growers. ETOH is the worst government supported "alternative energy" program in history. There's no ETOH free gas for 100's of miles in central Texas, its all tainted.
If you can't make butanol out of cellulose, corn, shrimp shells etc then don't bother.

I have observed an increase in fuel economy using non ethanol as well. Not in my EB, but in my 96 Geo metro. I realized a 5-8% gain. This was on a car with 69k miles and tracking mileage over 25k miles, hand calculated.
Unfortunately, 100% fuel has pretty much dried up around here, so I haven't been able to play with it on the EB.
BTW, some stations stock high octane (93) in ethanol free. So, you not only get the benefit of the higher octane/timing boost, you get the higher energy content as well.
Well written post, keep up the good work.

Another problem I forgot to mention is that ethanol burns slower, in some cases this can be beneficial, but for the most part means that less will be burned, more will be wasted, and less power will be generated. I am not a proponent of ethanol at all, but Ford must have tuned knowing that 10% mix would be used.

The lie that ethanol will reduce our dependency on oil is propagated by our government and the only way it is "cost effective" is because of government subsidies.
Thanks for posting the link to the gas station website, I wasn't aware of that and will be using these more in the future.

One thig is to is that truck is brand new I know they say brake in is 5k. but Most motors will change threw out there life and I think the best performace is between about 10 - 20 k miles, I know this is a big debate also about proper brake in and what but what ever take it or leave it.

It all boils down to BTU content:
Gas - 114,500
E85 - 81,800
Ethanol has a much shorter carbon chain, therefore less carbon atoms, and therefore less energy per unit.

I just wanted to pick on the bit of your post that I quoted here. I wish everyone would understand that Ethanol does NOTHING to reduce our oil consumption. It takes more energy (oil) to create ethanol than you get out of it. This is due to the fact that farmers use diesel powered equipment to grow the corn to make the fuel.
The lie that ethanol will reduce our dependency on oil is propagated by our government and the only way it is "cost effective" is because of government subsidies.

......and let's not forget about the fact that we are now using "FOOD" for fuel. Five,six years ago, corn was around $3.00 a bushel (right at the beginning of big subsidies)....now we're over $7.00 a bushel........
