I think there are more pluses than just that.
From
http://www.cytoculture.com/Biodiesel Handbook.htm#Lower Hydrocarbon Emissions
"As an oxygenated vegetable hydrocarbon, Biodiesel itself burns
cleanly, but it also improves the efficiency of combustion in blends
with petroleum fuel. As a result of cleaner emissions, there will be
reduced air and water pollution from boats operated on Biodiesel
blends. At a 20% Biodiesel blend, there will be a noticeable change in
the odor and smoke in the exhaust. Older engines should also emit less
soot under load and less carbon black during startup.
Independent research programs in Europe and the U.S. have shown that
Biodiesel in a 20 percent blend with petroleum diesel created a
significant reduction in visible smoke and odor. The studies documented
the reduction in hydrocarbons, carbon monoxide and particulate matter."
Fine particualte matter is especially dubious as it seems to be
implicated in a lot of lung cancer.
