amanites,
This is a pro-active website joined by a large number of enthusiasts happy to help anyone in need of help. However, a person trying to milk the knowledge of others without any minimal effort of investigating his problems is not a good reflection on persons moralities and certainly not having any appreciation on the professionalism of the people who joined this website in good faith. I have googled the biodiesel properties and the first page gives a wealth of information what you obviously missed because you did not even bother to do a minimal research of your own. You are suppose to be an active participant in this forum, and get as much as you give, because this is not a cheap way to get your work done. For your information, some biodiesel fluids will gel at a temperatures above 0 deg C, others will gel at temperature below 0 deg C. Do some study and we'll be happy to help you out if you show some effort and some respect for the people in this forum.
Best regards,

gr2vessels, that was a sharp one.
But I cannot say I disagree, I found dozens of resources by simple google search.
Amanites, based on your biodiesel type, you would need at least two viscosities at reference temperatures. You can visit Razaghi Meyer webiste for downloading ASTM D341 viscosity calculation sheet for various hydrocarbon mixtures.
This is OT to the OP but it is not OT to the first response. Since this site is a 'tips' site I often want to respond by giving the tip - "USE GOOGLE" and then if you can't answer your question, we will try to help. I agree with gr2...
Regarding the OP, I would think that bio-diesel is such a mish mash of who knows what, be careful about taking any one value as gospel. Your "bio-diesel" depending on where you get it might be any combination of fuels including distillate made from bio products, e.g. soy beans to used cooking oils and petroleum distillate blends. The properties could range all over the map.
Unless I had intimate knowledge of what someone was pumping while calling it bio-diesel, I'd always be suspicious.
You don't have to answer any question. If you don't want to...

From NREL Publication, "Biodiesel Analytical Methods" Shands, Pruszko, 2004
ASTM D 6751–02 sets the specifications that must be met for a fatty acid ester product to carry the designation “BIODIESEL FUEL” or “B100”. Products that meet the specification, by
implication, will perform properly as a compression ignition fuel either as B100 or in
blends with any petroleum-derived diesel fuel defined by ASTM Specification D 975
Grades 1-D, 2-D, and low sulfur 1-D and 2-D.
----------------------------------------------
Kinematic Viscosity - Viscosity is a measure of a fluid’s resistance to flow. The greater
the viscosity, the less readily the liquid flows. The viscosity of petroleum oils is a strong
function of temperature with the viscosity decreasing as the temperature increases.
ASTM D 445 is a standard test procedure for determining the kinematic viscosity of
liquids. Biodiesel is more viscous than No. 2 diesel fuel but only by a small amount.
Depending on feedstock and amount of oxidation, biodiesel viscosity will vary between
4.0 and 6.2, while No. 2 diesel fuels tend to fall in the a narrower range of 2.4 to 2.6.
I have always maintained that those who are too lazy to "GOOGLE" the simplest and most obvious of search terms are those who are not willing to add anything to these fora. Furthermore, I suspect that they get some kind of twisted pleasure at exploiting those who are, perhaps over anxious to help
If someone has the ability to post on this forum, they have the ability to perform at least the most minimal of web-searches for themselves
