The best you can do is buy tires with low(er) rolling resistance and run higher inflation pressures. Outside of that, keep up on maintenance and drive with a light foot.

Sell it or park it until we get another administration with a more responsible energy agenda.

0.75 MPG increase. I know that doesn't sound like a lot but it all adds up over time.

Although many seem to think I am promoting snake oil but I have noticed a nice improvement in my mileage after treating my engine with an anti-friction or friction modifier ceramic product that binds to the metal. You use once every 25k miles. I use these products in all 3 of my vehicles.
My personal reasoning for using such a product is actually reducing cold start wear as much as possible but reduced friction also means better mileage. Win win. I will say this, how fast you drive plays a big difference. The GX is not aerodynamic.
In the city she is a dog and almost nothing you can do but look at this example below. By driving around 55 - 60 mph and with the Liqui Moly Cera Tec treatment combined with using 0w-20 M1 EP motor oil I can easily get 24 - 25 mpg on mostly level ground. 22 mpg when the weather is particularly cold. I’m also running 93 octane and I use MMO pretty regularly to clean the fuel system as well as the engine. 65 - 75 mph it will drop down to around 20 mpg.
I’m running Wildpeaks which decreased my mileage from a street tire. Lowering the truck and running a tire with the lowest rolling resistance would obviously help as well.
This trip I am demonstrating I averaged over 25 mpg. Pretty damn good considering. Hopefully the pics speak for themselves.

Saving fuel by tricking the engine into running leaner is not something I would ever do. And while I’m no expert, I know a lot more than most people do about engines and tuning. It might work. It might not cause long term lean fuel problems - like burning a hole in the top of your pistons. Yes that’s a real thing if you run lean enough long enough. But why anyone would do it to save ten dollars a month in gas is a mystery to me.

City driving will about see no gains in MPG's no matter what you do. Long hwy driving might see a smidge better MPG's (if you can accurately detect it).
The only real gain seen in lubricating advantages to save fuel is 0w16. This is likely the last of heavy $$ R&D in this area for ICE engines as most of the makers are going eV.

Aerodynamics is an area to look at. All GX's are big boxes against the air. What can be done to lower air drag, that I do not know.

I certainly wouldn’t buy a GX or LX for fuel mileage, but I look at a vehicle’s efficiency. True that Toyotas are much more reliable than anything GM puts out, but it seems as though Toyota just doesn’t care that their box on wheels is not efficient, just that it sells.

True statement. If Toyota was really concerned about better mpg, they sure wouldn’t had designed the new Tundra to be so hideous. I had a 2006 Tundra & it was much sleeker than the new pickup & got decent mpg from the small V-8. The same could be true for the GX. If you look at the mpg for GM’s full size SUVs, they are much better that anything Toyota puts out.

Ford ecoboost and others like it, probably all get better MPG's than anything normally aspirated by Toyota. The big diff is though, Toyota NA engines will run much longer. So to get into this comparison need to 1st pick similar technology. GX470 was ranked #1 for going the distance, 300kmi+. I posted that link in the GX470 forum. GX460 probably gonna be the same.
