Removing ethanol from gasoline

Gasoline makes our bikes go. Ethanol is not conducive to a healthy bike. End of story.

Removing ethanol from gas poses several benefits; since ethanol is incredibly hygroscopic (bonds with water easily), it pulls moisture from w atmosphere and traps it. This new blend is heavier than gas, and sinks to the bottom of the tank, where it gets sucked into your fuel system.

Ethanol is also detrimental to rubber pieces and gaskets.

Removing ethanol gives you pure gas. Wonderful.

The procedure is simple: add water to gas.

How you decide to do this is up to you, but be careful - gas eats certain containers, and dissolves certain chemicals in other containers.

Here is what I do:

I have a 5 gallon tank with a length of pvc hose coming off the spout, and a valve at the end. I add a cup of DISTILLLED water per gallon of gas (can't have too much water) and shake the hell out of it. This bonds the water and ethanol. Then, I sit the gas can upside down in a jig, with the lowest point being where the spout connects to the can. I let it sit for a while, and drain out the water, followed by the water/ethanol mix, since both are heavier than gas. You now have pure gas.

Note: removing ethanol reduces octane - use 93 octane to achieve "regular gas" octane. If using 87, get an octane booster.

Sticky?

So, I'm going to spend the extra money to buy premium gas, do all the work you discribe so I can have a few gallons of Ethonal free fuel.

My bike runs fine on the 10% stuff and if I figure the extra cost on cleaning the fuel out that way to the slight increase in power it just ain't worth it.

There are stations here that sell regular gas without Ethonal, but I've never bothered to hunt them down.

I can see this usefull perhaps to those that can only buy the 15% crap in their area......but you won't get that much water in your fuel tank from the Ethonal absorbing it if you just ride your bike alot.....

Anymore you don't have to go out of your way to find Ethanol free gas in South Carolina. We also have some stations that carry racing fuel, blue gas or avgas. HAven't tried that yet as it's like 7-10 bucks a gallon but I may this summer :-)

We've got one pump of E-free, it's 93 octane though and well over $4/gal. So lose/lose to me on buying it at the pump.

This pic must be the same effect of separating the ethanol, this is weedeater gas dumped out of a no-start, it fired right up with good gas. Water formed in the tank, got shook up, then settled out the water and corn.... :

I wouldn't waste money on racing gas for my bike, there's no benefit. But I do miss the smell of burning Cam2, and Klotz! I've been known to run it just for the aroma.

Like the distinct aroma of a 2 stroke burning nitro oil. :-)

Actually almost 90% of the corn grown in the US is not for human consumption. It's mostly for cattle feed and other "corn products". There are several varieties of corn and the type we eat is not even the same type.
So really (I read your sarcasm there) it's not taking food out of our mouths. But yes, the whole Ethonal thing is stupid.
