E10 E5 Fuel conditioning additives

Guys, it's not only the degradation of rubber and seals to worry about with E10, there's also acidity and potential corrosion, or so I'm told.

Anyone using Millers or Lucas fuel conditioners yet?

Can corrosion be prevented by simply draining over winter or coating the tank? Mine is already coated with POR15. Also are aluminium or nitrile rubber lines affected?

Thoughts?

It appears to be saying that it is advised to replace any fuel containing ethanol with some that doesn't if you are not running regularly.

I'm going to do that this weekend as I have some E10 fuel in the tank so I will just transfer it to my 2015 daily driver. I have used the millers in the past and it was good for lead replacement but not tried it with unleaded since the conversion.

Just done a search and it appears that the only Ethanol-free fuel is ESSO synergy Supreme+ 97/99 octane. All the other super-unleaded fuels contain up to 5% ethanol. The Millers VSPe is maily a Lead replacement but it does say that it inhibits Ethanol. To what extent, is unknown.
