A local fuel supplier has recently started carrying B-20. My 2004 PSD runs well with it and I'm happy with the lubricating properties of biodiesel. As winter approaches I'm wondering if I should use anti-gel fuel additive or if biodiesel is blended in winter like #2 Diesel is. Anyone know the pourpoint of B-20? I suppose I could always put a jar of it in the freezer and see what happens.
Be aware of biodiesel's cold weather properties and take precautions
as with #2 petrodiesel use in cold weather.
A 20 percent blend of biodiesel with petrodiesel usually raises the cold
weather properties 2 to 10° F (pour point, cloud point, cold filter plugging
point). In most cases, this has not been an issue. Twenty percent biodiesel
blends have been used in the upper Wisconsin area and in Iowa during -25°
F weather without issues. Solutions to biodiesel winter operability problems
are the same solutions used with conventional #2 petrodiesel (use a pour
point depressant, blend with #1diesel, use engine block or fuel filter heaters
on the engine, store the vehicles near or in a building, etc.).
I personally have not had any cold weather issues using bio yet. Last winter when I went to go snowboarding i was running soy b100 and it got down to the low 30's and my truck started up perfectly in the morning. The cloud points also depend greatly on the feedstock the bio is made from.
where i live we see 30 to 50 below 0 a lot in january and febuary and we have a dealer that sells B 50 in the summer and B5 all winter ..he adds some anti-gel stuff to it but i still run white bottle DK in it and carry a bottle of diesel 911..i have had no problems and still have a new bottle of 911..
