Yesterday's short hop, 94 miles on a state 2-lane road, cruising at 62mph yielded 20.8mpg.

god bless your light sweet feet
No, curvy, rolling hills. Late morning on a Sunday and country church hadn’t let out. The light slower traffic was easily passed. The drive was set on Comfort. I used adaptive cruise and let the GX do most of the driving.

With about 8000 miles under the hood, the car has been averaging about 17.7 mpg.
My highest was about 20.5 but on the highway, I can hit about 18-19 while cruising at about 70 mph.

You do realize zero miles indicated isn't empty... even if you run it down to when it stops giving you a number and says "refuel," you still have over 3 gallons remaining in your 21.1 gallon tank.
I've also noticed that whatever the car states for your MPG is actually s little conservative (not surprising given how conservatively Lexus/Toyota handle remaining fuel). I did a mostly highway jaunt today of about 200 miles. I had reset the MPG when I started. It stated 20.2 MPG, while my calculations yielded 21.0. This is consistent with how every tank has been during the roughly 5500 miles I've had the vehicle.
Did a highway drive to airport and back for 76 miles and noted 20.8 mpg. I do note the milage is quite poor when it is cold out and warming up in the drive, even going easy. After 7600 miles we are still on at 18.3 mpg avg. So on a long cruise it does well, I did get 23 on highway once for a 100+ mile cruise. If you enjoy the torque of the engine it will not hesitate to suck fuel like an ol 4 barrel carburetor dipping into the secondaries! Stop and go or slow moving traffic on and off the accelerator will dip it to 15-16 range even when seemingly being conscious of saving fuel.

After 44 logged fill-ups, I'm averaging 14.28 mpg.
Average gallons pumped in is 17.64 with an average of 3.62 gallons remaining in the tank.
Average miles driven per tank (corrected for the larger tires with a correction factor of 7.192%) is 254.7 miles.
A seamless 16-gallon saddle tank from Long Range America that you could use without too much trouble would certainly be appreciated.
Having an extra 16 gallons on board, even assuming I'd only use 13 gallons leaving 3 gallons in the saddle tank with each fill-up (similar to what I'm leaving in the stock tank), would translate to an additional 185 miles I could drive between fill-ups. That would be 437 miles per "tanks".
If the full 16 saddle tank gallons were used between fill-ups then that would mean an additional 228 miles between fill-ups. Totaling 480 miles per "tanks".
Nearly doubling my mileage would save me 1 fill-up per week which would save 5 miles round trip to Costco gas station and a half hour. Over a year that would be 260 miles and 26 hours saved. That time is significant to me.

What do we know about Lexus warranty if such additional gas tanks are installed?
The first rule of additional gas tanks is that we don't talk about additional gas tanks.
Some of you guys are reporting fantastic mpg compared to my experience so far.
I drive mostly highway - but local highways - not interstate so there is plenty of slow down and speed up
type of traveling.
My best tank to date is 16.8 mpg with my last at 15.09. Lowest was 13.7.
This is taken by dividing actual miles by gallons needed to fill back up - not the onboard computer and not based on a
point to point drive.
Typical fill up is 16-17 gallons while still showing 20-40 miles left on display.
I get about 250 miles a tank. Way different than the Yukon is have that gets almost 570 miles a tank.

That sounds about right for me as well. I live on the coast and we have a lot of hills and off-shore winds to contend with and that can really affects milage. My wife has a RAV4 Hybrid and these conditions have the same affect on her milage. Its going to vary for a lot of situations including temperature. One day I'll get 18+ for a particular trip and the next day get 14.3 for the exact same trip. Wind and temp could be the difference or it could be my driving. I've decided to just drive it like a truck and not monitor it. Saves some frustration.
Is Long Range America some cheap china shit? I didn’t think so, will have to check.
No, they are Australian manufactured. I’m good with that.
Seems a good option to consider. I love the look of a swing out tire and stout bumper but it often gets in the way at camp and decreases visibility. Why did the GX not get the digital rear view mirror?
The GX should most definitely have received a stock digital rear view mirror!
I don't like the swing-away tire carriers. Sometimes they are a necessity, though.
A rear-bumped-mounted spare on the GX550 looks horrible in my opinion. It's definitely a wart on what is (or was) a fine looking backside. The truck clearly wasn't designed to have a spare on the back.
The worst thing about a swing-away spare tire carrier is actually living with it every day. They are a major pain in the ass. You'll find yourself using the cargo area only when absolutely necessary and you end up stuffing cargo in the back seats instead of the cargo bay.
