Today, how does the Ritz's fuel efficiency hold up?

When the Maruti Ritz was produced, it was well known for being fuel efficient, but how does it stand up to today’s standards in that regard? Many Indian car buyers are looking for a fuel efficient car, which could make or break the desirability of the Ritz in the used car market. As per some owners, the Ritz even with older models manages to give impressive mileage figures, but for some, the mileage drops over time. The car’s fuel efficiency is a product of how old the car is, how well maintained it was, and driving conditions. The Ritz's real world fuel economy could be compared against newer models in the same segment to get an idea of how good Maruti's engineering has held up.
