The difference in energy content between pure gasoline and E10 is approximately 3%. I've been able to measure an approximately 3% difference in fuel trims in my vehicle - I made separate fuel maps for ethanol-free fuel and E10.
Here in the 'states, E0 is almost always high octane "Premium" fuel. If you need to run high octane fuel anyway it's an obvious choice, but it does not pay for itself vs regular grade.
@Zunigrijje, your 18.5% improvement doesn't line up with the energy content difference between the fuels, or what I've been able to measure in my own vehicle.
