Ah ok.. If you don't want to venture into the world of car things, find an independent, legit, knowledgeable, respectable mechanic who is time proven. Even better if it's a toyota/lexus only mechanic. Tell them your gs300 is using way more fuel than it needs to and they will perform testing on your car and suggest. You don't wanna blindly throw parts at the car. If the mechanic is good they can diagnose with a high probability a failing component.
ALso some 2006 gses are kinda sorta lemon cars, being the first year an all. They admitted that some 2006 gses require replacement of engine computer and oxygen sensors followed by an OIL CHANGE(!) because the faulty computer/sensors combo dumps way more fuel and it dillutes the oil.
Open your oil cap, does it smell like dat HIGH OCTANE GAS??

11 MPG is a serious issue. It could also be dumping gas into the cats hurting them as well.
It is possible during the recall that a hose wasn't put back right or the intake manifold not bolted down correctly, even a missing gasket somewhere. Then air is let in and extra fuel compensated.
That is pretty amateur, newbie DIY work but I'm sure it happens in dealerships under time pressure. And honestly, dealers may take anyone if they really need a body.
A scan tool would reveal fuel trims or other issues. The dealer can do a quick diag or you can search for a reputable shop. Some owners take pride in their work.
If you want to get your hands dirty there are certainly apps (even the toytoa one) for very cheap, and you can post results here. Best thing is fixing it yourself.

There are ones for a few dollars less but he has good reviews.
This tool lets you see TPMS, reprogram keys, etc. It is what Lexus will charge $150-200 to connect.

What does your typical mpg look like and what kind of driving do you do? Admittedly some days I drive a very short route with stop and go traffic, but even that shouldn't justify 11mpg under any circumstance. If it's rated 19mpg city I expect to get somewhere near 19mpg. I can't even get that cruising down the highway at 65mph for an hour.
I never thought in a million years I'd own a V6 sedan that gets 11mpg. I've owned similar equipped sports sedans that get double the gas mileage. I've owned v8 sports cars and V8 trucks that get way better gas mileage. It's pathetic and Lexus should be ashamed of themselves(they aren't).

Do a bit of reading on fuel trims, there are good videos on YT by scannerdanner and others. You have to understand fuel control, vacuum leaks, etc.
It is important to have knowledge with an older or even newer car, unless you like being taken advantage of. You are at the mercy of the tech and he could cost you thousands if he don't know what he is doing. You can get factory parts on ebay for real cheap, at the dealer everything is marked up and a $50 sensor ends up as a $700 bill. The less you know the better customer you are!
Sometimes an ECU can be bad, dumping fuel, but I think with that tool you could buy a used one and recode it to your car.

My car has always gotten ****ty gas mileage. It just seems a little worse after the recall. But I was never getting above 13mpg as it was. Where I live there are no good independent mechanics within 30 miles. There is a Toyota dealer down the road but I know they will overcharge me for what could potentially be nothing wrong.
Make sure your exhaust has no pinholes either. This is meant for the other gentleman having problems as well.

You are going to be looking for pending codes, fuel trims at idle, 1500, and 2500 rpm, misfires, etc.

I would do anything to get 23mpg. What was your mpg before the recall and exhaust work? I wonder if I call Lexus if they can do anything since the mpg got worse after recall?

I drive to and from work on the city roads and the hwy. Mostly stop and go traffic a lot. The lowest MPG that I seen was 16-MPG. 11-mpg is really bad. I want to sell my car, but I just don't want another car note. I think that I should just do it because my car sucks-up 2-quarts of oil every month as well.
My car was not like this before the recalls.
