Heating oil is generally a lower quality than diesel fuel, since it is
intended to be burnt for heat and not in a more demanding application
like a diesel engine.  The winter/summer differences apply to both
fuels, to ensure that they don't get too viscous or solid from wax
precipitation to interfere with equipment operation.  Manufacturers
tailer the fuel according to the climate it is going to.  For example
fuel going to the interior of BC would have to withstand colder
temperatures than fuel going to the lower mainland where it is always

hope this helps
