If the ECU had invoked 'limp mode' due to some engine malfunction, I'd expect the yellow EML would be showing. The OP hasn't mentioned it. They can apparently assume a limp-like mode without the EML, but I sense this case isn't one of those.

Have you checked for fuel leaks? The loss of petrol from one of the two tank module seals is pretty common, especially in cars that have had recent tank work done. This causes a strong smell of petrol under one or other rear wheel arch.

a brim test needs to be done to determine the fuel usage,any fuel leaks would be apparent by smell.
my guess is that the car is in need of a service,when was the last time one was carried out?

I used to have a ZT 1.8T manual. It did around 32mpg brim to brim.
