My son has swithched to a Pellet Heating insert, for the majority of
heat. He has a boiler, that had supplied Both his home heat as well as
his hot water. He is now using FAR less " heating" oil. That boiler
continues to supply the hot water
My question: Should he add any preservative (ala Stabil for gasoline)
to his oil tank. He used to use a few tanks a year, now less than one
refill per year.

Algae are a life form found in water, similar to algae growing in an
aquarium. Algae do not live in fuel and it requires sunlight to grow.
For years, people have been referring to tank sludge and the jelly,
slime and other contaminants found in fuel filters as algae. The
colloquialism diesel fuel algae is widely used and understood.
However, there is no relationship between the algae growing in your
aquarium and the sludge growing (forming) in your fuel tank and
showing up on your filter elements.
There are three basic areas of concern about contaminants in fuel and
2. Inorganic debris (sand, dust, rust, etc.)
3. Organic debris (fuel breakdown products and waste products of fuel
deterioration and re-polymerization)
The organic debris represents more than 90% of all contaminants found
in fuels and oil. It is this organic debris, the sludgy, slimy, acidic
material that people refer to as diesel fuel algae. It could also be
called a polymer, tar, wax or asphalt!

Alternativly ...is it possible that there was something about the design of
the new tanks that allowed more water or condensation to form inside?
Was the venting similar?
In the summer when the heating oil is not being used, I like to seal the ve
nt with aluminum foil , just to slow down the intake of moisture a little.
Used to be that fuel for "prolonged storage" and backup power had
"algaecide" added in greater ammonts than standard fuel,and all fuel
oil had some. Quite possibly not there in today's low sulphur fuels.
There are additives you can buy and add to fuel oil for long term
