general question concerning diesel fuel

[kenisret]

I recently drained some fuel into a clean glass jar to check for water in the fuel. I noticed after a few days the fuel had turned very cloudy after standing. The jar was tightly sealed during this time. Just curious if this is normal.

Was it cold?
