Does this product prevent "phase separation" ( process causing ethanol to draw moisture into gasoline)?

for what it's worth, I have a 2016 Mustang that I run Ethanol only and have for 5 years. Planning to get this to see if it helps any incase I do have buildup, but it sits from Nov to March every winter with a full tank of Ethanol and has never had a problems from it. We get wet winters.

Is this designed for winter storage of e85 fueled vehicles? Full tank sitting for up to 6 months of winter temperatures 20 -40 degrees F.

There are two answers. If premium fuel 93 Octane is fresh in the tank just prior to storage the Lucas product will be OK. Longer than 6 months I would go with Stabil or like product which is advertised for 12 months. If you utilize less than 93 Octane premium fuel then use Stabil for 6-12 months of storage. Colin

will this get rid of water in the fuel

The advertisement/label says it keeps the water from separating out. I've been using it for about 6 months now and have E85 stored in 5 gallon cans. Seems to be working

How long can I store straight E85 in a proper gas container while using this stuff?

I have been around car trucks tractors etc. all my life. I Store gasoline in plastic 5 gal jug for up to 6 to 8 months with no problems. Gas stays fresh and no repairs needed in my carb. or fuel inj. motors. But I can not tell how long it work in e85. Hope this helps
