I've been running B5 for a while now and like it, but I'm getting ready to fill up again, and fill my 100 gallon reserve tank. That amount of fuel should last me untill the end of December. Where I am living now, the lakes start to freeze over in about 2-3 weeks from now. I have heard and read on the pump where I get the B5, that it gels worse than #2 in cold weather. Is this something a good anti-gel additive will take care of? Thanks

 

I run B5 year round in all farm equipment and on road vehicles. I order my fuel with a winter additive package from my distributer year round so there is no question what fuel is in what. I have had no problems except when I got a load of B20 and it was -10. Had to add some extra antigel to that load.

 

Im wondering too, if I have a tankfull of B99 and I go to Tahoe for a few days where the weather drops to 20 degrees out, am I going to have problems?

 

Cloud point (temp at which wax crystals begin to form) of B99 can be well above 32 F, depending on source of the stock oil, moisture content and other factors. Soybean biodiesel will gel at around 30 F, but even before it gels, the wax crystals can clog filters. To test your fuel's condition, drain some fuel from your HFCM and put it in a jar in the freezer. When it starts to cloud up, measure the temperature of the fuel and you'll know where the cloud point is. If the temps are expected to fall that low, cut the ratio down with D1 or D2 and use lots of antigel.
