I’d like to measure full to full but I rarely put more than 30quid in, seems pointless to lug fuel weight about
Pretty sure your maths may be a bit out - the tank is 80L which is 17.6 gallons. Actually puts you at max 29mpg I reckon.

The best ive every seen across a whole tank is 28.9 mpg and im averaging about 21 over 12k miles. I still think all things considered the car is decent enough on fuel.
