15 year old, so c. 2010.
I can easily belive it, though the closest Civic mpg report I found was for a 2012-14 model:
What is the fuel economy, Honda Civic IX Hatchback 2.2 i-DTEC (150 Hp)?
4.4 l/100 km
53.46 US mpg
64.2 UK mpg
22.73 km/l

American cars just aren't at all efficient by anyone else's standards.
