The myth about partially empty tanks is pretty well established...I just left a tank COMPLTELY empty for 2 years...no water...the other was a 1/4 full....no water.
There are empty tanks lying around my bosses salvage yard...empty...no water.
The slightest amount that MAY he present is usually handled very nicely by a Racor.
There MAY be areas or situations where condensation MAY reach appreciable levels...haven't seen or heard of them yet...but will pass that along when I state the above if someone provides it.
I agree with trying to improve lubricity in untreated diesel (my marina "claims" to have Valvetech ) just not sure about most additives as many claim a long list of improvements but ultimately independent testing has shown them to decrease lubricity.
Wish there was a biodiesel place close by...it usually gets good ratings as a small percentage additive.
