octane is the index to resist knock. alcohol fuel and gasoline have different air to fuel ratio need. you need more fuel if using alcohol to get same output as gasoline fuel.
gasoline stoich AFR is 14.7:1 while E10 AFR is around 14.12:1. that means, for gasoline, you need 14.7 part of air to burn 1 part of fuel. but you need 14.12 part of air to burn 1 part of e10. that means, for the same amount of air, more e10 needed than gasoline.
