Which will use the less Gas when Fridge in normal use and freeezer compartment not needed??
1. Leave the freexer empty.?
2. Fill the compartment with already frozen blocks.?
3. Fill with scrunched up newspapers.?
As Jim said, if the door is not opened (and does not "leak" )I would think it makes no difference, but if it's empty, and the door is opened all the cold air will drop out, which is why it is better to run a 'fridge or freezer full, (I think!)
