possible benefit of ethanol?

[lone wolf]

I'm in the environmental bizz mainly remediation and tank removal. I've pulled many tanks out of the ground cleaned many tanks underground and plenty of other things. Ethanol appears to be very corrosive. It will actually eat fiberglass very slowly over time. (Most new tanks are fiberglass go figure) I've also herd from the science guys that it is horrible on the engines carb or injectors. As for gas freezing ethanol has little effect. Condensation in the tank is the problem. Even if your fuel station moves a large volume of fuel. More likely to get condensation from a 1/2 full tank to a full tank. Depends a lot on the refinery too. You should see diesel tanks on the inside. Very dirty most of the time we can shovel the sludge.

Man peo

It said somewhere ethanol freezes at -172 ??? I think it helps. I think partly because most people drive their vehicles on a daily basis. And the tank never accumulates much water.

Ethanol is crap fuel period! I cant tell how much trouble it has caused me!

Let's put it in perspective...
I don't use ethanol blended gasoline in anything... and I never have... that's fact.
The last time I experienced fuel system freeze-up in anything was at least 25 years ago... and I don't use HEET, or any other additive... that's also fact.
So what does that say??

If it keeps my plow truck running in the cold, I'll take it. I still try to buy non ethanol for my saws. And I keep my gas cans sealed.

It says your using ethanol gas with out knowing it...

Now think about it the reason that they use non ethanol in planes is because of water it can freeze , see now?

There is probably a LOT of truth in that statement. I tried to get some non ethanol fuel from the only place that claims to sell it around me and after testing it....................found out it did in fact contain ethanol.

Nearly every gas station 'round here sells 87 octane non-ethanol blended gasoline... truth is, I can only think of one that don't. Several sell 91-92 octane non-ethanol blended gasoline. Things change a bit in towns like Waterloo or Mason City, but ethanol-free still ain't difficult to find. Heck, I travel all over Iowa for work and I've never been forced to buy ethanol-blended fuel.
If what you say is true, I'd have reported them in a heartbeat... that's plain theft by deception... and the fine in Iowa is friggin' huge‼

You haven't driven in 25years?

The bias ply thing might be making sense now....

I've seen videos where people added water to ethanol gas , shook it up, and let it sit overnight. The water and alcohol combined and separated from the gas. If it was shook up again it all mix together again. Have you ever had whiskey and water? Water and alcohol mix real nice.

Water and ethanol are completely MISCIBLE when combined. That means you mix any amount of ethanol in water (and vice versa) and it will form a SOLUTION. (Note that methanol and propanol are also completely miscible with water.) That is not the problem.

The problem is keeping the ethanol or a solution of ethanol plus water blended into the gasoline. As Spidey mentioned, there is relatively little water that a 10% ethanol gasoline blend can absorb before the ethanol-water component separates from the gasoline into an AQUEOUS LAYER (water plus things that dissolve easily into a water--like ethanol). When this happens, you get a layer of gasoline on top and a second layer of ethanol-water on the bottom. Guess where the fuel pickup is in most OPE? The bottom of the fuel tank. D'OH!

But it won't freeze. And what happens when you are driving? Does it mix or at least slosh around enough that you are getting some gas through the system? My truck can run on e-85 so the somewhat straight ethanol ain't a problem .

Try finding stations in the northeast without it. They're few and far between. Especially since it's illegal to use MTBE. But I do have a couple of gallons of "White Gas" that was on my grandfather's workbench when he died. I don't know how old it is... it's in old, soldered steel maple syrup cans. I know it's at least 25 years old. But it still smells like gasoline.

Run it and post results very interesting.

The water is going to be there ethanol or not.. the question is will it freeze if combined with ethanol? I say no. A tablespoon of straight water moving through the line in straight gas could freeze if it sits there overnight. Or maybe even when driving.

I hate ethanol just as much as everyone else. But I'm mostly talking about new vehicles that are designed to run on it. There are few if any disadvantages to running it in them and I'm thinking this is one of the advantages. .

I thought Ethanol attracted water?

Ok ,the new fuel systems are not vented. Condensation is the water source. Which a occurs with or without ethanol in cold temps.

So do you run Ethanol gas in all you saws and machines also? That stuff cause problems I tell you!
