Removing Ethanol from Gasoline

[comptiger5000]

However, keep this in mind: if people are using higher octane fuels, the manufacturers can build in more optimum timing, higher compression, and possibly even turbos to get more power from a smaller engine, while getting good gas mileage (more compression = more efficient in terms of BSFC). If they really got fancy, you'd be able to de-rate it to run on regular fuel as well.

Cant really argue with that concept - but I still think Ethanol at best is the "clean coal" of the "green fuels"

essentially you are burning the fossil fuels of tomorrow today and calling it renewable - all energy sources have their costs associated with them and with ethanol the cost is pretty high in terms of the environment - not as high as fossil fuels....but between the fertilizers, water usage, transportation of materials and the exhaust - it is hurting us more than helping in my opinion.

If we were using the waste associated with farming/forestry/agriculture rather than actively growing a crop with the intention of turning that into fuel then I would be more supportive - but then again I think you get methanol that way not ethanol (which has an even lower energy density but is much better for the environment - much worse for cars in terms of energy density and galvanic corrosion)

Hmmm...wonder how far OT we can go....sorry I suspect that my fault...I dont know how to get ethanol out of a fuel mix. There back OT.

With testing the washed E10 gas vs E0 to help and check if some of the gain in MPG is from washing things other than just ethanol, you could wash a batch of E0. So you would run a tank or two of E0 then run a tank of washed E0 and see what the difference is if any.

Another thing to try is to add the water from the E10 experiment to the E0, shake, then drain off the water. Maybe a tiny amount of ethanol is acting as a detergent to keep a small amount of water mixed in the gasoline, giving similar effects to having a water injection system.

I've been doing this for a long time and I trust my testing methods after revising them slightly over the years to be more thorough, but I always suggest that people get their own test equipment and do their own testing.
Different cars and set-ups can and do react differently, and the more testing being done out there, the more little discoveries will be made.

I will try your method olympiadis and see the results. Thanks for the input by the way. I have tried other methods recommended by the mechanic but unfortunately it did not go well for my car.

Well, I have a small anecdotal input as well as some ranting to feel better...

In Oregon there are counties that are required to pump E10 and some that are not, mostly the farm counties.

They have pumps labeled E0 Farm use only.

My 94 Jeep with a 2.5 4cyl thats been rebuilt with power in mind gets a consistent 17Mpg when driving from the Portland Oregon area.

When I get to the dry side of the state out east, and fill with the E0 I immediately get a nice 4 or 5 MPG bump. Very consistent and repeatable for the last 7 years.

BTW E85 is 15 percent Eth becasue if it was E100 any chemical company could distribute and haul it, with over 5% Gasoline you have to be a Oil distributor to stock and sell it.... Hmm.

My farmer relatives in Nebraska tell me that ANY crop they can get cash for that makes bio-diesel or alcohol needs to have 2x the fertilizer of crops grown for food. And Chevron is the biggest manufacturer of fertilizer... besides cows... Grow soy and you get the double win of pumping chevron and Monsanto... Wheeeeee

Cane is an awful top soil destroyer and needs massive amounts of fertilizer or fresh ground to grow it on,,, IE rain forest. about 80% of the ethanol in our gas comes from Brazil...

I work on a 850 HP methanol burning sprint car, we spend hours cleaning crud out of the injection system.

But if you are running alcohol there is a Product from Klotz called uplon that works wonders at stopping the corrosion issues...

Just some random thoughts form the peanut gallery....

^I seriously doubt these

What will happen if our car's gas tank is accidentally poured with water.

[Allch Chcar]

It depends on how much water. Too much and it'll run horrible or stall. You'll have to drain the tank and start over.

Pro/con depends on what your agenda is. I (pro) like the renewableness of it, and the oxygenatedability, and the domestic supply, and the money savings to me too. Con... I dunno what they're all excited about. Whatever.

Wow I neglected this thread for a while. I have some issues with these statements frank.

I am not sure do you actually believe this or is this just info you got elsewhere and have had no reason to doubt it?

None of what you state is true.

It is not cleaner. it does NOT help with domestic supply and its NOT renewable any more easily than Oil is.

First with a car DESIGNED to run on ethanol its SLIGHTLY cleaner. maybe but only if you COMPLETELY ignore the pollution on the Production side of the equation. If you goal is to actually reduce pollution you can't ignore this.

Domestic Supply? you do realize that for some what 75% or greater the cars on the road it INCREASES demand for foreign oil.

10 gallons of E10

REMOVE the Ethanol and you get 1 gallon of Ethanol and 9 Gallons of Gas.

I can go FURTHER on 9 gallons of gasoline than I can on 10 gallons of E10.

Think about that for a moment. Think about the implications of that.

Let us also not forget that Ethanol production using in DISGUSTING MASSIVE INSANE QUANTITIES another resource even more valuable and rare than OIL is.

FRESH WATER. and it has to be FRESH WATER salt water won't work.

they using simply preposterous amounts of fresh water to MAKE ethanol.

there is NO upside to ethanol unless your taxing it or your grow it.

For everyone else its nothing but downside.

Ethanol BY DEFINITION can not save you money. it can ONLY cost you money.
