Running Ethanol
Curious if anybody else is running on ethanol?
I have an 07 5.4 flex fuel and did an experiment for one of the classes that I teach. I drove 10 tanks gas, kept track of mileage and cost. Got about 16 mpg Then I switched and started driving on ethanol. I have been getting only 12.5 mpg. I knew there was going to be less but this was way less. I still have a few more tanks to go through before I finish the experiment and calculate the cost between the two. I have been getting E-85 for $3.29. Gas now is 3.85.
Also, did an experiment testing emissions as well. Ethanol produces far less CO2 and emissions. And my exhaust smells like moonshine.

One thing I've noticed running E-85 in a 2008 is that the mileage drop is not linear based on percentage of alcohol in the tank. If I fill the tank holding gas at half empty with E-85 (essentially mixing to make roughly E-50) there is not much of a drop in mileage. When you reach higher concentrations of E-85 in the tank the mileage really dives. Something to do with the engine management software/monitoring I imagine.
I watch mileage in realtime using a Scangauge II hooked to the OBD port. Since I tow and haul stuff long distances I've been able to save a chunk on fuel this way plus I have the optional large cap tank and sometimes carry a portable 30 gallon to take advantage of low gas/E85 prices I come across.
