Poor mpg

Hello

I have a C3 2007 1.6 v16 automatic that is doing a very poor mpg at around 18 mpg average, could the fault be in the injectors, o2 sensors or anything else?

No fault code detected

Please have a look at some torque pro info that I collected this morning.

Any help is appreciated

Thanks

Hi

Are you actually getting a poor mpg based on the quantity of fuel filled into the tank and the miles you have driven?

Or is this only from a computer display?

Did the consumption suddenly change?

Can you scan for codes with a different scanner?

Hi
Thank you for the reply

I'm actually getting 18 mpg "calculated by filling" driving only short trips in London.

I recently bought the car so im not sure whether this is a recent problem as the car hasn't moved much in the past year "50 miles only" and 21k miles overall.

Sadly i don't have access yo a lexia, I'm using a Bluetooth obd2 and torque pro, i can try different apps tho.

Do you recommend trying some fuel cleaner as it could be a dirty injector issue?

Would removing and cleaning the O2 sensor make sense?

Thanks again for your help.
