Default An easy way to rid mogas of ethanol..

A local friend of mine has old hotrods...55 Chevy, crotch rocket Kawasaki and he won't run mogas with ethanol.

He takes a modified 55 gallon drum to the gas station with 5 gallons of water in it and then buys 40 gallons of mogas. The water attracts the alcohol, just like in the test and becomes 9 gallons of water/alcohol mix (10% alcohol is 4 gallons, plus the 5 gallons of water).

He added a drain valve that lets the water/alchy mix out until he sees/smells gas...pretty simple really.

Best,

and then the remaining fuel is of a much lower grade than originally, right? Does he put any of that fuel in high compression engines?

Default How do you figure that?

Ethanol laced gas has less power than non-alcohol IIRC,

Best,

Ethanol has less energy content than gasoline, as you suggested, but acts as an octane booster, I understand. So removing it would tend to lower the octane of the remaining gasoline.

I suppose that what he drains off is served straight up on the rocks.

i believe it is like david said. here is a quote that somewhat shows the numbers underlying the problem with trying to remove ethanol at home

"# It is obvious that there is an economic incentive for terminals to blend ethanol, the direct tax credit. But there is another more subtle and insidious incentive for refineries to get all of their distributors to blend E10. Once that happens they can ship "suboctane" gasoline to the terminals. Since blending ethanol at 10% or higher raises the Anti Knock Index (AKI) by more than 3 points, refineries can produce and ship 84 AKI gasoline for regular unleaded E10 blending. This is already happening in Oregon. They can also ship 89 AKI gasoline for premium unleaded blending. Suboctane gasoline costs less to produce and more product results from every barrel of oil.
# The most acute problem for aviation is that if the premium unleaded is taken suboctane, when all gasoline is E10, there will be no 91+ AKI unleaded gasoline made, which is required for 100 HP Rotax LSA engines and Petersen high compression STCs."

from the e0pc.com web page talking points

What does he do with the nine gallons of water/ethanol?

Just say no to the ethanol scam.

Default Oregon etonol free

It seems the Peoples Republic of Oregon has seen fit to sell ethanol free high octane gas at the pump. My recollection is that ethanol is added at the distribution site. If one can get to these locations can we purchase ethanol free gas? I seem to recall there is an airport at El Paso that sells mogas ethanol free as they buy from a local refinery.
