Gelling temp for b20?
 

Anyone know the gelling temp for B20?

I live in northern Oregon, and run B-80 down to 0 deg, I don't think you'll have to worry about B-20 gelling where you live! I haven't seen any specs on B-20 gell point because I think it is a non-issue.

sounds good!

Phydeaux is going to have to expain how that works. I don't get how a blend of #2 diesel, which gels just below freezing, and biodiesel, which gels slightly above freezing can have a gel point lower than both????

I think you meant me, Scott:-missingt

Here in Northern Oregon our fuel suppliers blend 15-20% Kerosene with D-2 for winter use. Our winter fuel is good to about -20F. Normal wintertime temps aren't usually that cold, BUT once in a while we get sub-zero weather. 2 years ago it went to 18 below and stayed there for 3 weeks.

Actually I did mean Phudeaux88. I was thinking there was some sort of chemical reaction that lowered the gel point when the two were mixed. I was going to have the resident chemist explain it.

Of course, now that I know your fuel is blended I need no further explanation. I appreciate you clearing that up ;)

It's a little complicated to explain here but it has to do with the way molecules of a pure substance interact with each other during transition from one state (liquid) to another state (solid). When you mix in foriegn molecules you interfere with this interaction.

Thats why antifreeze works.
