fuel
Mine always used more during the winter months, but I put this down to running more electrics, heated screen heated seats, heater's,headlights etc, this puts the engine under more load so hence the drop in fuel consumption

could have a good few reasons and some add a bit here and there = to a good few miles less to the gallon .
But as said diameter in tyres will vary you miles clocked .
I would also have a look at the diesel , ie are you buying at the same place most times ?
If so change and see ... Also in the winter the mix in the diesel is changed re frost , leading to a lesser effeciency of the diesel . Postmanpat

Noticed sluggish performance and substantial fuel economy drop (4-5MPG) recently. Diagnosed replacement MAF by disconnecting it and noticing significant performance gains.

I haven't been far enough to see if the fuel economy has improved, but it is possible that this is the same problem.

Think summer winter fuel consumption is evened out by the need for all the electrical kit during the winter. (Headlights, heater, fan etc. )

Random but easy to check - make sure your fuel pressure regulator isn't leaking

So.. just thought I'd check mine, 2005 90

... a week or 3 commuting 10k to and from work,
then over the Alps and thro San Bernadino and down to Tuscany,
some tracks down there on a friends property,
back over the alps,
an 'ab gas' (exhaust ) test - at 4800 rpm !! , (long story, getting it registered in Switzerland)
a bit more commuting.
all in all - what a Landy is for really.
941 miles (assuming it's correct), 148l. 29 mpg if my finger are right. Very Happy Sold the much modified 110 2.8, in Oz
Brought the 90 home from Switzerland ...
