With the increase in 'heavy oil' already making it harder to meet the octane requirements, it make no sense (except for a few rich dilettantes like litesong that can pay extra for a bit more 'range') to remove the ethanol EVER.
....... a rich dilettante.......never been described such......that's because the description isn't accurate & LHMF knows it. My current fuel cost per mile using 100% gasoline in my new LUXURY car(Elantra-$15500-it is a luxury car to me) is a bit over 10 cents. For my Ford Festiva, cost per mile, using 100% gasoline is 8.7 cents. Current cost for the average american in my area using 10% ethanol blends is ~16 cents per mile.
A bit more range...... for every 100,000 miles I drive using 100% gasoline, ethanol blend would only give 92,000 miles. My Elantra, using 87 octane, 100% gasoline, & bad-mouthed by leadfooters getting only sub-30mpg, who complained that Elantra wasn't able to get the EPA city or highway mpg-------currently I am averaging 39mpg with a high of 43mpg(possibly more mpg above that).
