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
The ethanol won't separate out and your car would't run if it did.

You must be driving uphill for the first 1/4 tank.
