I have a 1995 with 177k miles. When the engine thermal control valve was stuck open (better than closed!) it got 17 and was dropping. Fixed that and it shot right back up to 20 for mixed driving with climate control on auto. (auto climate control kicks the A/C on and off when it think it's needed.)
Anyway, I'm planning a road trip and I hope to break my 20.5mpg record on the trip!
PS: don't run your tank down frequently, because when Skynet Goes online, you'll need to drive and drive far! . Seriously, try to keep 1/4 tank as a goal so you can get places when things happen and keep crap out of your fuel filter.

Manual or Auto a/c mode really shouldn't matter or be noticeable for mpg's whereas system on or off will.
Unless Toyota has really changed something in the most recent years, if the A/C light is lit the system's pretty much going to cycle the compressor at measured/programmed intervals regardless of the variable fan speed or vent mode that the auto feature is running the cabin controls in for the passengers' desired comfort level.
So far with probably about 60/40 Hwy/City (A/C OFF the whole time!) I've mildly exceeded 20mpg per tank in the first 2 fill-ups at the first signs of the low-fuel light for my 94 LS400 cruising at average speeds above the posted limit...
The car's still idling high (1,200 rpm's cold or hot whenever it's not in gear) and running rich at all times like it's never warmed up, even with a brand new Toyota thermostat and the temp gauge sitting normal, not sure why yet.
I'm expecting my fuel economy to improve considerably if I slow down to posted speeds and/or find my high idle problem, and it should get much better if I solve both of those "problems" eventually.

Epa mpg
At the EPA website (www.Fueleconomy.gov) the estimated mpg is 16/23. These are the revised estimates and are probably lower that what was originally on the window sticker. I think that this thread proves that how you drive is as important as what you drive.
Fans of Top Gear may remember the episode where they drove a Prius around their track as fast as it could go, recorded the gas mileage, then drove a BMW 3 series around the track at the same speed & time, and the BMW got better gas mileage.

I notice a considerable difference between city/traffic and open highway. I haven't had the car long enough to do only highway (which is what I do in my Toyota Matrix). Matrix I get 33.
Combined city/highway (50/50) driving in the LS I'm getting about 21 (18 if my wife is driving). Highway seems to be about 24-25.

For those wondering how? CAREFUL throttle modulation. A STEADY throttle foot along with carefully timed use of power. SLOWLY accelerate when going downhill and allow the car to SLOWLY decelerate going uphill. Of course I am talking about minor up and down hill situations on interstate driving. Your throttle foot should get VERY smooth with NO input unless NEEDED. Select the averge MPH readout and watch what it does as you drive. Over time you should be able to improve your "style" and get more efficiency.
