So, I bought the alc-free gas, and did our normal driving pattern and got 11.9 mpg. (!)
Then, bought the ethanol gas and after our normal driving pattern, got 12.4 mpg. Hm.
So again, I'm going to say it depends on your vehicle, and perhaps your driving patterns. I'm glad we did it, because it's just more food for thought.
On one hand....to fill our tank, alc free gas costs $4 to $6 more, and if we're not getting better mileage, it's not worth it thriftywise.
On the other hand, I do tend to shop at gas stations that are alc free because the stations around here tend to be independently owned and I like supporting small businesses.
On the other hand, looking at the environment, gas has hidden costs such as drilling, refining, shipping. Gas with ethanol has all of that, plus the hidden cost of growing corn (water, fertilizing, harvesting), refining, and then shipping to gas refineries to make final products.
On the other hand, producing ethanol actual creates energy so perhaps it works out in the end.
And in the immortal words of Tevye (surely you got the idea from all my 'other hands'?) what people buy is mostly based on TRADITIOOOON! Perhaps not the gas they they've always bought (On the other hand, ethanol has been in our gas since the 80's) but on traditional thinking surrounding supporting gas or ag or large chains or independent station owners. Or perhaps the tradition of buying whatever costs less regardless of the long term cost.
