Hydrous ethanol (without gasoline in the mix) can be preheated before injection increasing millage by 50%. Such preheating with gasoline in the mix is not possible because of damage to the engine, US law should NOT require petroleum (gasoline) as the SOLE denaturing agent for fuel grade ethanol because ethanol and petroleum compete as internal combustion engines fuel of choice.

And it's main advantage is that it cost less to be made. With flex fuel cars here we blend in the car any mix of gas (here each liter of gas has 25% anhydrous ethanol) and hydrous ethanol. The main disadvantage is to turn the car on in cool morning, but technology already has solved this problem with a very smal gas tank (less than a liter), that is used just to turn on the car.

Any blender selling hydrous would have to make it clear that the product had water in it, and that could be a difficult sell to consumers who for decades have considered water in fuel to be a bad thing. There would be substantial energy saving in producing hydrous v. anhydrous. About 20% of the energy a still consumes is spent getting that last 5% or water out. But let's be sure we make it crystal clear to consumers the facts of the product we expect them to buy. They would be correct in thinking that hydrous should be 10-15% less expensive to purchase than anhydrous.
