Ethanol wants to absorb moisture so it will pull it out of anything if it’s available.

Could be. I never looked into it. I just dont put ethonal fuel in my classic cars. Also my small engines hate it. So I try to stay away from it in them. My standard cars run it.
Ethanol isnt very stable in gas. Not sure how long it lasts without breaking down.
I wish they just get rid of out of the fuel. Standard gasoline lasts alot longer then the mixed fuel.

What is this closed loop u speak of? I just obtained a scan gauge from my friend and did even read about it. It’s in my truck for a couple of months and I don’t know how to operate it.

The only way you will see if it’s closed loop is if the scanner reads live data. Cheap scanners will only read the diagnostic codes.
Closed Loop is when the engine starts using the front O2 sensor to control the fuel mixture(14.7:1 air fuel ratio) In open loop it runs very rich (around 12:1 air fuel ratio) to not burn up the engine. The extra fuel it uses running rich will effect fuel milage and it can also gas your oil.

I run high test in all my small engines. Ethanol has never been a problem for me. High test will last a year untreated before it starts to skunk.

I've got about 27 years under my belt as a motorcycle mechanic, so I've worked right through the change in fuel. "Bad" gas can be a whole lot of things, but when talking about age it nearly always comes down to oxidization. Pure gas can go about a year before it starts having issues, same was true for the MTBE years (was fully phased out by about 2000). Ethanol fuel can go about 3~4 months, though if you're in a HOT climate, a month might be showing problems. On a similar vein, if the fuel is kept in a sealed container (the new gas cans that don't vent) that's as full as possible (as little headspace/air), it can go longer. The reason for the short time is that the H2O it absorbs is introducing more oxygen that causes the fuel to "varnish" and go bad. It's no longer just the surface touching air, but now it's the moisture being pulled out of the air and into the fluid too....
Octane ratings have NOTHING to do with time before gas degradation. Sorry, you can think that all you want but it's not going to make it true. In some, rare, cases the higher octane fuel have less ethanol (or did, I haven't seen any in a long time), but it's a safe assumption that the base fuel platform is the same for any given brand, and the Only difference is extra additives to rise the octane.
Get into additives like StaBil, and you can get most of a year out of ethanol fuel in most cases (extreme heat and a nearly empty tank would be the major exceptions). I'm sure most of the additives are the same, I've just been a StaBil user for decades and haven't had need to look elsewhere.
If you have small engines that see only occasional use and want to give them the best fighting chance, drain the carb float bowl after every use. No, running it till it stops is not good enough (it'll actually make things worse). Then, fully top off the fuel tank. I've made a lot of money over the years cleaning motorcycle carbs in the spring, the people who heed my advice never come back (well, for that service, it usually earns me a lot of Other work though). those who don't, I get to see year after year after year....

I drain my carbs out of all my small engines. I still occasionally have to clean old carbs out because of the ethonal eating the varnish and lacquer out of the fuel system. I believe this is why we are seeing these fuel systems filter and screens plugging up in these 3rd gen 4runners. The ethonal is eating the systems out cleaning it out. I just wonder what components in our systems can be damaged by it?

My 01 gets between 15.5-16 (on a good day).
Interesting part is my '15 sequoia w/a 5.7 gets better mileage, not by much but it does, 16.5 (mixed in town and highway), haha.

Just did 249.8 miles on 14.49 gallons for just over 17mpg. That’s with Costco regular.
That’s with the Volvo MAF in 98 5sp, stock except 265/70r16 BFG AT T/A’s.
I warm up to 120 water temp before rolling

129.8 miles on a 14.49 gallons is about 9 miles a gallon or am I missing something?

My 96' SR5 gets 12-14 mpg, 70% freeway @ 60-65mph. I have a Sonoran Steel 1.2(3"lift), a 1" body lift, welded on sliders, full under armor, ARB front bumper, tundra front brakes, a Tepui roof top tent mounted on a Thule system, running 285x70x17 Terra Ridge Grapplers mounted on Method 17x8.5,et 0 wheels. I also have a rear custom drawer system. Its easy to forget its 23 years old and has 160,xxx miles. It dosent burn oil and always starts. I dont think theres any gas driven 4WD on the market today that would get me 20 mpg setup the same way, and it would be a $50,000 truck pre- build!!

I fixed it. Not sure how I fat fingered that.
