I got E-10 woes with "Charlotte"- water in gas and looking for a permanent fix!

Sounds like it ain't the E10 that's the problem, but rather the vendor not maintaining his equipment/tanks. Buy your fuel somewhere else. BTW - I run various combinations of E10-E85 in my B/Cuda & have only had trouble when I let the car sit for 6 months - but then again, I would've had that trouble w/ straight gas, too.
