Having seen the clean inside of the prior 8 year old, almost certainly completely neglected old tank, I have a feeling Southern California boaters are treated pretty gently by the environmnent and maybe we can slide by on a few of these rules.
I think that is a great choice, down the road you can see if you want to keep if filled, you have the safety reserve which will relieve you of one extra concern, and when the day comes that a fellow sailor needs assistance you have the fuel to stay on station and giv'em a hand.
yep keeping additive in diesel is the way to protect it, your fuel cell and ultimately your filters.
