Completely false. It is neither the water content nor sulfur content that requires an oil to be called "#6", according to the specifications defined by the American Society for Testing and Materials (ASTM).

The bottom line is that the only ones claiming that JBI's #6 isn't really #6 are message board posters, and not JBI.

The toxicity of #6 oil isn't related to it's sulfur content. Rather, it is because of numerous other toxic compounds found in all #6 oil:

FUEL OIL NUMBER 6 ENVIRONMENTAL HAZARD SUMMARY

"In the aquatic environment, the main concern is the
aromatics in Fuel oil 6. Benzene, Toluene, Ethyl
Benzene, and Toluene (BTEX) compounds, although
they do not make up a large percentage of this
product, are present and could represent an acute
toxicity risk. Due to their relative persistence
and potential for various chronic effects (like
carcinogenicity), the heavier aromatic PAHs, (and
particularly the alkyl PAHs) in Fuel oil 6 can pose
long term (chronic) hazards in contaminated soils,
sediments, and groundwater.
Heavy oils (Including Heavy Crude Oils, No. 6 fuel,
and Bunker C) are prone to severe impacts to
waterfowl and fur-bearing mammals (coating and
ingestion) [741,777]. They may weather slowly, and
potentially sink (depending on product density and
water density) to impact benthic organisms.
Many of the PAHs found in this product (see
Chem.Detail section below) are more toxic in
sunlight or other UV source than elsewhere (see
PAHs as a group entry).
One of the hazardous groups of compounds in fuel
oil is PAHs. PAHs may be translocated in plants and
may accumulate in plants grown in contaminated soil
[40]. Presumably this also occurs in sediments and
aquatic plants and therefore might impact
herbivorous species of fish and wildlife. Although
some research seems to indicate that interior
portions of above-ground vegetables do not
accumulate high concentrations of PAHs, plants do
translocate PAHs from roots to other plant parts,
such as developing shoots [40]. Some plants can
evidently catabolize benzo(a)pyrene, but metabolic
pathways have not been clearly defined. This is an
important factor since when PAHs do degrade through
metabolism, they often break down into even more
toxic, carcinogenic, and mutagenic compounds [40].
Metabolic transformations of PAHs into even more
hazardous chemicals could also happen through
microbial degradation of PAHs in soils or
sediments. This provides an additional example of
a situation where human health based standards are
not protective of fish and wildlife, since it casts
doubt on the environmental safety margin provided
by EPA's human health-based soil guideline of =<100
ppm carcinogenic PAHs."

Hazards to Humans:
Fuel oil #6 would be expected to be a skin, eye and
respiratory irritant and a CNS depressant from
inhalation of large amounts of the vapor or mist.
Prolonged or repeated contact with the skin may
produce a defatting dermatitis with dryness and
cracking. This product may contain substances
which have caused kidney damage in laboratory
animals [369].
Chronic effects of some of the constituents in fuel
6 (such as naphthalenes) include changes in the
liver and kidney [766].
Exposure to petroleum in soil is predominantly of
concern through a number of possible exposure
pathways, including dermal contact with soil,
ingestion of soil, inhalation of soil particulates,
and ingestion of contaminated groundwater [824].
