Just Got Back From A Hot Shot Trip To North Dakota And While In -14 Degree Weather Started Having Power Problems It Was Discovered That Bio Diesel When Exposed To Extremly Coled Weather Will Form A Thick Resedue In Your External Fuel Tank If It Sits For To Long Even After Being Treated With Anti Gel And B Y The Time We Made It To The End Of The Tank We Were Driving On The Equivelent Of Corn Oil.

 

Bio gels pretty quick. At -14* I'm surprised if flowed at all.
