ethanol has about 2/3 of the energy content of gasoline per unit volume, IIRC. At the 10% (max?) level, that would be roughly a 3% decrease in mpg, everything else the same. So more like apples and 3% different apples...
3 things:
1. "E10" aint always E10. The amount of ethanol added to the gasoline isnt closely monitored. Some gasoline has been found to have as much as 30% ethanol when tested.
2. Ethanol raises the octane, so the premium is alway going to have a higher percentage of ethanol than the regular.
3. Have you ever personally compared the mileage of pure gas to that containing some amount of ethanol over the course of a few tankfuls?
Point being, any talk of MPG is pointless unless you know miles per gallon of what. Especially if one is going to the lengths that the OP went to to measure and obtain optimal mileage.
One thing to think about, if its only a difference in energy content of 3%, why is the difference in price of pure gas and "E10" much greater than 3%? Trust me, you aint getting free energy.
By the way, I commend the OP for his efforts. But I would get that front diff fixed asap and that driveshaft back in. Until then, I guess what you have is a "Land Runner". haha

My fuel likely had 10% ethanol cause I can't find pure unleaded anywhere here sadly. Remember, I filled up, literally got on the on-ramp, and drove highway nearly 100% of the time straight to getting off the highway and filling up again. I cannot repeat this with any measurable in-town driving...this was literally a purely hwy trip. But I really did it...my wife was a witness. I even told her no one would believe me As for getting flipped the little birdie...yeah, it's a definite downside. I did this once just for my own experiment. E9999, that is some dry cracking on my tires which is crazy since they are only a year old...who knows how long they sat in the Sam's club warehouse before I bought them

You can easily find out.

So, I checked that website against my stamped code on my tires. They were manufactured the 48th week of 2012. We had them installed on the truck January 2 of 2013. So I have no ode why they dry rotted so fast around the rim area.
I can get 32mpg, but it is a 4.2 diesel....
I don't believe it, lying liars of mud!

I'm impressed. I bet that helps your wallet when fuel is $8/gallon across the pond.
I believe it. If the hyper milers can get 78mpg in a diesel Passat, almost twice the epa hwy miles, I certainly believe it's possible to get 23 out of a land cruiser.
And the record holders agree with the op: leaving it in drive uses less fuel than shifting into neutral.

Reading this thread made me think about a conversation a buddy of mine and I had about how he could get 18mpg at 75mph in his 5.3 Suburban and why didn't my Land Cruiser do as well. What would you say?
The suburban is geared different.
edit:
A343F Transmission
Gear Ratios:
Hydra-Matic 6L80, six-speed automatic
Gear ratios:
First:
4.03
Second:
2.36
Third:
1.53
Fourth:
1.15
Fifth:
0.85
Sixth:
0.67
axles: 3.08
I think a lot of it has to do with the gear ratios in the axles, and the overdrive ratio (top gear) on the transmission. The engine in the suburban is spinning much slower at 75 mph compared to the one in the LC.

It is, but isn't part of it that the drivetrain components are lighter as well?
The gear ratios make the biggest difference. Depending on year model, your hundy is probably heavier than his suburban as well. Check Edmund's.com under features and specs to get the weights for each. My 01 lx weighs in right where it's supposed to, at 5700 lbs. I haven't weighed my 99 lc, but I will next time I take something to the city dump.
$8.00 per gallon, I wish, it's $11.00 per gallon over here......
I seem to be able to pickup .5 to 1 mpg using the 2nd start feature
I get 17.5+ mpg using 91 octane
have you gentlemen who are running 33s confirmed your actual mileage using a GPS unit?
I have seen +7% across 3 different Toyota trucks
