Freezing (waxing) point of modern Diesel

With current temperatures getting down to -20°C (-26°C apparently in Scotland last night), I was wondering what is the temperature the modern Diesel starts to Wax or freeze (I know it's a lower temperature than Petrol) ?

Lol. I think petrol freezes at something like -70c!!

Correction: -43c for petrol, and about -50c for diesel.
From around September onwards, the fuel companies start to add anti waxing chemicals to the fuel to prevent any problems so I wouldn't be worrying
i was also wondering what temperature does engine oil freeze at (rough figure - i know diff oils may be diff temperatures)
I don't think you need to worry about engine oils or fuels in this country.
