22/100 is extremely high and unusual for a car like yours.
I would class it as above double acceptable consumption.
Of course, we need to look at the other variables first.
Age of drivers, what transmission, hilly terrain, stop start traffic etc.
Who does your servicing, and have you mentioned this before?
Some more info to consider.
Lots of short trips, excessive idling, traffic jams, stop start traffic etc increases fuel consumption.
Has a mechanic looked at your car as yet?
I hope my advice has been of assistance to you.
Your question is still open.
Do you need any further help?
