Just did a bit of an experiment. I filled up with good old (sarcasm) E-10 87 octane at Buccees on Wednesday night. Drove into New Orleans and made it to my parent's house on fumes. 377 miles on the dot.
Found a station in N.O. that proudly proclaimed "NO ALCOHOL IN OUR FUEL!" Filled up there with 87 octane, ran around town a bit, then drove back to Texas. A total of 389 miles. I STILL HAVE OVER 1/8 of a tank left after driving to school and back today!
Now y'all, I'm pretty bad at math, but with about 3 gallons left in my tank now and having traveled 12 more miles, I reckon that E-10 gives me 17 mpg and pure gasoline gave me 20.5 MPG.
Someone do the math for me and figure out how many percentage points E-10 is less efficient than pure gasoline.
As near as I can tell, this is a huge difference. The ethanol in our gas might as well be dissolved AIR.
