Reduced Range on Full Tank

Hello, I have a 2015 persona. The range has recently decreased from 480 to 430. I am very happy to read the suggestions on this page. Does anyone have a recommendation for a New York City mechanic who will address this issue for me?
Thank you and nice to make everyone's acquaintance.

Reduced range almost certainly means that your average MPG has fallen, for whatever reason. It could be mechanical, or weather, or just a simple change in your driving patterns or speeds or routes and distances, or changes in the traffic congestion that you must deal with.

Absent some more substantial clues to the cause or some specific problem, taking it to a mechanic for a remedy is very likely a waste of your money and the mechanic's time and patience. They normally don't do well on generic loss-of-MPG concerns.
