What exactly "contains 10% ethanol" do?

Hi,

After installing Pedro's technotorque I started watching more closely my MPG and I noticed an interesting trend.

Normally I make around 20MPG (up from 16-17 before technotorque),
however I noticed that if I use gas with ethanol, sometimes first half of quarter is gone in 10 miles, after that it's the normal 80 miles per quarter of tank.

This never happens when I fill in with pure gas (extremely hard to find here in Seattle), and sometimes even if I fill gas with ethanol it behaves normaly..

So I'm thinking that "contains 10% ethanol" might fill my tank with more ethanol (it's not like it's mixed perfectly at the station) and if this happens my mileage for the first 10-15 miles sucks, after ethanol is gone .. it goes back to normal.

Am I paranoid?

Thanks
Sasha
