Seeing as E10 only has 2-3% less energy content then 100% Dino fuel you can't blaim it alone a 2.5mpg loss. I've done ALOT of switching back and forth on many vehicles and at MOST I've seen a 2mpg difference in highway mileage, and that's on my Fusion, City mileage is virtually unchanged. More than likely the biggest change comes from cooler morning temps and the fact that our mileage is down until the tranny gets above 120*f. I know my "Instant Mileage" is down 2-3mpg on my 5.0l until my tranny gets warmed up above 120*f, same goes for my neighbors Ecoboost which really effects mileage in the morning for both our trucks. My Fusion goes from 29mpg summer to 24mpg winter in my work drive due to the fact the tranny doesn't warm up enough allow converter lockup when it gets below 0*f on my 12 mile trip. Personally I think Corn gas is a bad idea but it gets blamed for a lot of stuff it shouldn't.

A Petro-Canada station up the highway from my house has 94 Octane Plus gas. That's the only thing I ever run in my truck.

Meaner than ymeski56
I've noticed it going down over my past 2 tanks. Plus I can't seem to find pure gas in any of the stations around here so it's already bad to begin with. 5.4 4x4 with 3.31s and I haven't hit 18 yet...

Not trying to start anything, but it wasn't too long ago when we made a huge push in WI to kill the mandatory 10% in Milwaukee metro area, and the govt' almost did it, because it was proven to reduce mileage a fairly significant amount. Not to mention all the issues with small engines etc. If I didnt have to re-tune to run the 91, I would make the drive.

I am no Petrol eng., thus subject to correction, but in most parts of the country (USA) summer blend fuel has the oxygenates added and the BTU/gal content lowered. The winter blend actually would lead to higher MPGs. That being said several factors would lead to lower MPG during the colder temps. Our computers run our engines richer while cold and also the transmission operated differently to speed warm-up of the engine. Many drivers also pay extra for the privilege of lower MPG. The remote start allows us to get into a toasty truck, but we get a whopping 0 MPG while it sits there at low RPM and low load warming up. I would guess it takes 5 to 10 minutes to build the same heat it would by driving just a mile. The same can be said for idling while you scrape your windows. I had remote start on my last truck and intend to have it on my next truck, but it has a cost associated with it.
The octane argument has gone on since the days of Regular or Ethyl! Engines will get their best MPG when operated withy the lowest octane they can use without pre-ignition. 87 octane has a higher energy content than 107 octane racing gas. Most race cars could not operate on lower octane because the high compression would case premature detonation (dieseling). Does anyone know if the new direct injection engines have the compression, timing, or programming to take advantage of higher octane fuels?
Diesel fuels are the opposite of gas. Winter blend has a lower energy content than summer fuel. This is done to prevent fuel gelling at lower temps.

You guys are wussies. I fill my 5.0 up at a Chevron that is 100 miles away simply because the quality of the fuel at the only station in town can be unacceptable. I had issues when I had my Ecoboost powered Lincoln where it would start pinging and sometimes even buck after filling up here.
Since my commute to work is only 40 seconds long when I get the green at the only stoplight in town, I am usually able to time myself since I generally head up to Soldotna at least once every 3-4 weeks.
That said, I have noticed my fuel economy take a significant dive lately. However, as the above poster said this is hard to quantify because the conditions are different. Colder temps mean that I am idling longer in the morning, and the tires are exhibiting increased rolling resistance due to the colder weather. The fluids are also colder and thus exhibiting a higher amount of drag on the internal moving components, so there are tons are variables involved.
In Alaska, we get our petrol from California so I am sure it is garbage anyway.
