I'll let ya'll in on my master plan. I am not conserving diesel fuel. I
am hoarding it.
Between both boats, I've got close to 1000 gallons of diesel. I am
going to wait a couple of more years, then sell it by the gallon on E-bay
and make a fortune.

On a serious note - does diesel go bad like untreated gas?

I've been told no. You *do* have to treat it with a biocide, particularly
in warm climates, to avoid having little "critters" growing in it. I left
my boat unused in Florida for almost two years with full fuel tanks. Before
bringing it back north I had the fuel polished as a precaution (a process
of running the fuel through a set of filters to remove critter growth).
Turns out it was not necessary ... the regular Racor filters would have
handled the small amount of crap in the fuel without becoming clogged.

Otherwise, it does not "go bad".

I have had a couple of folks who run fuel docks tell me at different
times over the years that there really isn't a need to add biocide to
fuel sold for pleasure boating.

They claim that the fuel dock treats the fuel with biocide when it is
delivered from the refinery, and that this biocide transfers into the
fuel tanks of the boats taking on diesel.

I'm not going to say either way. An ounce of prevention, etc, you
know. However, in both cases the fuel dock operators successfully
persuaded me *not* to buy some biocide from them, so it's less likely
that they were spinning yarns than if they were trying to convince me
to spend more money.
