The viscosity (resistance to flow) for diesel is rated differently than gas. The higher the number on the diesel the higher the viscosity. In winter in Minnesota truckers stick to Number One diesel or a roughly 75/25 mix of one and two diesel fuels. Gas continues to flow freely at -40 but number 2 diesel looks like honey. Same with motor oils. 5W30 flows much easier than 20W50 so a car starts easier with the lower numbers.

Summer diesel fuel in Canada is rated at 0 degrees C. Full winter weight diesel is rated at -36 degrees C. Right now the fuel is in the blend stage from heavy weight to lite weight. Should be full winter weight by the beginning of November.

Depending on the type of diesel fuel(#1 or #2) it could begin to "gel" or freeze at around 30 degrees F.
The #2 fuel is much "thicker" and will "gel" at a higher temp.Where the #1 is lighter and "gels" at much lower temps.
As far as I know gasoline will not freeze.
