you guys need to be aware of cloud point of diesel, not just the gelling point. the clouding of diesel plugs up the filter faster then anything else.
from the wiki:
Like most fuels, diesel is a mix of hydrocarbons, and the components have different freezing points. For Number 2 diesel, as the ambient temperatures drop toward 32 degrees F (0 degrees C), it begins to cloud, due to the paraffin in the fuel solidifying. As the temperatures drop below 32 F, the molecules combine into solids, large enough to be stopped by the filter. This is known as the gel point, and generally occurs about 15 degrees F (-9.5 degrees C) below the cloud point.
So, using a winter blend or adding anti-gel additive/mixing kerosene to summer mix will prevent problems during the winter. In old days adding kero to diesel was used to lower cloud point or run straight kero when it is really cold, below 0.
