Why am I supposed to want to use "super unleaded" (gasoline with 10% ethanol)? Yes, it's about 10% cheaper than regular gas -- but gets about 10% less mileage. So it logically follows that my car runs 10% better on straight gasoline -- in other words, more power. So, all other things being equal (cost/gallon vs. miles/gallon cancelling each other out) -- it seems like straight gasoline would be the clear choice, giving you more power all the while. Unless I'm wrong about any of the things I stated above.
