Ultra-low sulfur diesel fuel affects lubrication

[Al]

Jimmy,
I would agree that biodiesel has a higher gel point than
Diesel. But when you are using as a blend, then the higher gel point
will not be noticable. I believe this article used 1 - 2% as a
basis. You would be able to run 1 - 2 % blend in any weather as long
as the other 98 - 99 % is petro diesel. If you would need to add
additives to petro diesel to keep from jelling, this wil take care of
the biodiesel blend as well.

The running of biodiesel is perfectly legal in the U.S.
Actually the emmissions are better on the environment than the petro
diesel product. It is endosed by the EPA and DOT. In fact, the
government is promoting it by dumping millions of dollars in
incentives to get the technology rolling becuase biodiesel is a
renewable resource.

Yes the biodiesel is a cleanser and will remove all the years of
petro diesel deposits. This will end up in your filter but after
your first tank full, your filter changes will go back to how you
changed filters before. I change all of my filters ( gas & oil )
every 5k miles as a preventative.

My mixture goes from 50 % ( B50 )to 100 % ( B100 ) based on the
time of the year. Of course I enjoy having about two days a year as
a winter season.

coal dust. I wouldn't hesitate to run a mixed blend of 20% Biodiesel,
to 80% Petrodiesel,(although Biodiesel is still illegal to use in the
US due to epa regulations) The problem with Biodiesel is that it has
a high gel rate, (+32*F) compared to Petrodiesel (-15*F) so if used
straight in cold weather, has to be preheated, in order to flow. the
other concern would be that Biodiesel has more solvents, than
Petrodiesel, which will disolve sludge that may be in the tank, so if
one decides to go this route, plan on changing the filters frequently
for a while. As for this new Ultra Low Sulpher Diesel, I wouldn't run
one drop of that, without at least some form of lubrication additive,
do to the fact, that it dosen't have enough Jimmy
