There are summer and winter blends of diesel. I was under the impression that the veggie oil needed warming all the time because all the kits have some type of warming scheme. Below a certain temp makes more sense though. 

I remember that from Idaho, when I had a diesel car (Chevette -- had the 1.6L Isuzu diesel in it). The stations would change over to "winter blend" in the fall. The fuel would gell below a certain temp, and one day a sudden cold front moved in. I went to work, and almost didn't get home! Car started, ran for about 100 yards, and shut off. Fuel was just starting to gell, so it started back up but didn't run like it should. I went and fueled up, and hte 1/2 tank of winter blend fixed the problem. I'd been warned about summer/winter blends or wouldn't have recognized it.
