I'm going to take 500ml of E10 gas, add 500 ml of water then see how they separate. If it is E10 I should end up with somewhere around 600 ml of water/ethanol and 400 ml of gas.
Gasoline contains alkylamine and alkyl phosphate detergents. As a chemist, I can tell you that those detergents are going to emulsify some of the water by forming reverse micelles. Essentially, some of the water is going to "dissolve" into the gasoline and probably nothing short of distillation would remove it.

Ethanol picks up 5% water unless it has been azeotroped. So you would be looking at 5% of 10%, or 0.5% overall. By directly exposing the gasoline to water, you would increase the overall water content by several times that amount.
Ok here's what I did. I have a 1000mL graduated cylinder that is marked every 10mL I have a gram scale and hydrometers, one .700 to .800 and another .900 to 1.000 both are 60/60 temperature rated. My thermometer is one degree graduations.
I used demineralized water at 68F and measured 1.000. Temperature correction is +.007 so I'll forgo them for this experiment.
E10 Gasoline SG was 0.730 at 68F, 500mL of it weighed 362
grams.
Water was 68F and 500 mL weighs 500 grams.
So after pouring in 500 mL of E10 and adding 500 mL of H2O I ended up with around the 550 H2O and 450 gas.
This kind of hard to see but if you look to the left side of the cylinder at the 550 mark you can see the line.
Here's another shot, the angle isn't the same and it's a different camera.

Congratulations you just lowered the octane of the gas.
How long did it take to separate?
