It's the same for me.
I think it's because it's winter.
Did you have the same problem last year?
I usually get 500 km (313 miles) per tank
In the winter I only get 400 km (250 miles) per tank.
I don't know if it's cold where you live but here in Sweden it makes a lot to the gasmilage.
For every cold start the choke is on for some minutes and the transmission (if you have automatic) don't shift as it's supposed to. So I think an engineblockheater would do a great difference.

Ok, step one, a fuel injected car does not have a choke, so that logic doesn't apply. Step two the electronic transmission in these cars behaves similiar hot vs, cold, with the exception of TCC operation, till fluid has warmed slightly and firmer shifts cold. That has minimal if any impact on fuel economy as the fluid in the trans warms rapidly when the torque converter is in open mode.
No body has mentioned the fact that when it is cold people tend to let there cars iddle longer to warm up in the cold.
The only annalogy that is corrects is that the air is colder and denser so that makes the engine use more fuel, it doesn't run richer, it just takes more fuel for that denser charge of cold air.
