It really defeats the point of getting a largish, heavy luxury car with a 300hp+ engine barely using the power just to save some money at the pump/on tires. I don't like wasting money and if I can save money on gas/tires within reason I will try to do it but I still like to enjoy the power and smoothness too. I knew when I got my GS430 and GS350 they were not going to get very good mileage aside from highway, I still wanted the power and performance, I just try to drive them less, luckily most of the time I have owned them gas prices were pretty low.

With gas prices rising since Jan and getting worse/staying high I don't drive as aggressively though and try to combine trips/errands, not drive as much, the trips to the pump are a little painful.

Also, I think the main goal of the OP was to find out if his MPG is out of line for this car and if there were ways to increase the MPG of the GS (to make it better). Why just accept it, if there is a way to make the car better?

I didn't buy the Lexus GS for gas mileage. I bought it to feel like I was going somewhere and enjoying the ride. I hate nothing more than to drive a gutless car. The Lexus is the only car I own that isn't a V8.

We don't have a improved or better GS, its dead now. There aren't really any alternatives to the GS that are as reliable, look like it, and offer its NA V6 experience so it is pretty obvious the OP and many of us like our GS's and don't want to just get something else with better mileage and more power yet. I am aware of the OP's goal, we answered him that it was not out of the ordinary to get his kind of mileage in NYC stop and go, aside from recommendations like tire pressure and clean air filter there is not much else unless you drive like a granny which I don't think many want to do in this type of car.
