The jury is out for me on additives. A yard manager with a lot of
credibility told me not to put anything in my fuel so I didn't for two
years. Then, I had just a few hiccups in an otherwise smooth running engine
with a nearly empty tank and began to find alge in the filter bowl. I put
in the StarTon and the bowl filled up with green stuff and the filter turned
green black although the engine ran fine. One tank of fuel after the filter
change, the bowl is clear. It certainly looks as if stuff was flushed out
of the tank that would otherwise be building up. Keeping it moving through
to the filter in smaller amounts instead of building up so that a big glob
gets sucked up in rough seas, which is when it invariably happens, seems
like a good idea.

Fuel isues on a commercial boat are very different than pleasure
craft. Commercial boats are in use almost every day, rarely sitting
around idle for any length of time. They are constantly taking on
fresh fuel with very high turnover rates.

Pleasure craft are almost totally the opposite with infrequent usage
for the most part. As a result fuel sits around in the tank for long
periods of time and even trace amounts of moisture become a breeding
ground for diesel bugs. Check the archives of the "Trawlers and
Trawlering" (T & T) mailing list. Fuel conditioning, fuel polishing
and filtration are *very* hot topics.
