Better off in a lower gear? (city cruising)

This tank is looking pretty lousy so far. I know the gas gauge can't be trusted for precise measurement, but I have a pretty good idea of what it looks like on a good tank.

I've been using 4th gear for city speeds of 30 mph or slightly above (1500 rpm or just a bit less for my gear ratio). Feels low on power, but smooth. The 2.9L 4cyl does not like the really low rpms that some drivers on here seem to utilize in their vehicles.

May it actually be more efficient to use 3rd gear, which would land me a bit shy of 2k rpm?

The shift indicator light usually goes on in the low 30's when I'm in 3rd and babying the throttle, and higher gears just make sense for FE...but my gas gauge seems to disagree.

I know the new route I've been taking (shorter, slower, a few more lights) may be at play here, but my goal is to keep above 23 mpg.

Any tips on gear selection?
