Making your own ETHANOL FREE Gasoline!!! it's easier than you think!!

Today I was getting ready to cut grass and I noticed I didn't have any Gas for the lawnmower. I thought it would make for a good video on how to make ETHANOL FREE Gasoline.
Many people debate the effects of ethanol in gas, but that isn't what this video is about! I will show you how to remove it with just Water, a siphon hose and a clear glass jar! check it out...

hope you enjoy this quick video!

I used to work as a lab worker in an organic extraction laboratory. Your gasoline, being cloudy is contaminated with emulsified water and needs to be "dehydrated" with anhydrous sodium sulfate (it grabs a lot of water from solvents). And, likewise the top layer in your one gallon plastic jug is the gasoline with emulsified water. Look at the lower water layer in the one gallon plastic jug and you can tell about 1/2" to 3/4" of water is emulsified in the gasoline. If you let the gasoline/water mixture sit overnight you'll probably notice the gasoline is clear again. Myself, I wouldn't use the cloudy gasoline in any engine because it has a ton of emulsified water along with ethanol in it! If the gasoline isn't perfectly clear then it's contaminated with water!

I’ve been purifying my gas for 2 years now I use a 5 gallon plastic carboy from Amazon and it has a petcock on the bottom . Some recommendations use distilled water mixed with blue or red Food dye the dye is water soluble and when the mixture separates it gives a clear delineation of the water/ ethanol mixture verses the purified gas. Ethanol burns slower and is part of the octane rating of the gasoline so if you start with a 93 octane rated fuel you’ll end up close to 87 octane. Note octane is actually isooctane which inhibits the rate of combustion and thereby decreases engine nock. Finally it takes a minimum of 12 hours for complete separation of the gas from the ethanol /water mixture . I always draw off the pure gasoline 24 hours after mixing.

I would probably have just siphoned the pure gasoline off the top down to maybe within an inch of the separation line and then kept the remainder for mixing into the next batch.

My bud used to do this, had a big canister with a petcock on the bottom to drain the water out.. used to leave the water/alcohol mix in a gas can in the gas can would mysteriously get emptied every now and then and one of the local kids would be selling a dirt bike or go kart a few days he would buy them and flip them.

Glycol (antifreeze) works better than water on separating and with 87 octane you drop to 84 and with 93 it will drop to 91-90 ish on octane. I work for one of the big oil company’s and we test loads that head to the stations for ethanol content this way. It can help a fella make some 90 rec when you are in a pinch.

Andy now to continue on..Take your ethanol/water mix and for that quantity add about 2 maybe 3 cups of salt and a small amount of food coloring and stir to dissolve it in the mix..then let it sit and the ethanol and the water will separate...then draw it off just the same. This method is called salting out.

[patrickbassaloff]

Actually discovered this technique by accident, my riding lawn wouldn’t run, so ended up emptying the gas into a old glass wine bottle, then had to stop for the evening... came back to it the next evening and noticed the amount of separation, out of curiosity I decided to add the separation of gas back into the lawn mower and I’ll be damned if it didn’t crank up ! 😮

Love your Reher and Morrison tee-shirt. I took their engine building class back in 2010. Thank you for the great informative videos!!!

[Bobcat]

I am giving you a big thumbs up for all the informative comments listed below. The explanations of engine knock, vaporization, ethylene glycol, ethanol subsidies, adding dye to the separation mixture, the safety warning about storing chemicals in unlabeled containers, etc. You have an excellent, well informed community following your content, and I commend them.

[jameslaurinitis]

Add some Toluene to the fuel and it will bump the octane rating right back up.

And Racor makes a water separation funnel. You could run the "pure" gasoline through it as a 2nd step just to make sure you have all the water our. Racor water separation filters are common items for boating.

Put a gas shutoff valve on your mower. Shut the valve off and run the mower til it dies after your last mow of the season or any time you are not going to run the engine. My honda started up first pull after not using it for a year. ALL gasoline will gum up your carb. Long before they came up with ethanol carbs plugged up.

When we had purple gas on the farm in the 70's and 80's, Dad got some clear jerrycans, filled them and left them out in the sun for a couple days. The purple dye would fade and we had red gas for the car.

[tarstarkusz]

I've made Coleman fuel from gasoline using heat to evaporate the lightest elements of the gasoline from the additives. Gas evaporates at a fairly low temperature. I used a cup warmer to do it to avoid flame and auto-combustion.

There's something new to me and I've been around a good bit! Thanks Andy. Luckily I got an ethanol -free station in the nearest town but this is very interesting and for me a useful thing to know. Three cheers!

Never had a problem with E-10 87 pump gas in my lawn mowers. I had a 20 yr. old Craftsmen lawn tractor that I used pump E-10 87 gas in for it's 20 yrs. Took the carb off to take a look
and it was shiny clean aluminum. Just don't store it with the carb full of gas.

[danielr.schafer]

I do the same thing with my old mower gas, no matter what you do it gets water in it! Put the gas in a large clear bottle like a dish soap bottle key part here is the valve, add gas and water shake let separation happen turn bottle over and open valve top squeeze out water… your done, put the rest in your tank! You could just decant your mix like wine but you may get some water in your tank, if your not very careful. Dont worry about octane its a mower after all.

I have a small airport about a mile from me and I buy my chainsaw and splitter gas from there. Aviation fuel doesn't have ethanol, is higher in octane and has stabilizer in it already. All this for about two dollars more per gallon.

[Nobamaable]

The gasoline should be clear and have a straw color. Yours appears to have entrained water in it making it appear cloudy. As an old aviation mechanic that did fuel samples every morning on our Coast Guard aircraft, I wouldn't use that gasoline in my engines. I'm a bit skeptical on your theory of removing ALL of the water from the gas...the entrained water still exists. Still a cool video.

[firstielasty]

Ethanol is not just soluble in water, it is miscible, so mixes completely at any ratio...so I think the layer in the milk jug at the end is some gas, rather than ethanol. It wouldn't mix just long enough to transfer out of the gas can, then suddenly divide into separate phases just because it's in a different container.
I use avgas in mowers for the last mow of the season, not because it is 100 octane, but because of its storage properties, it will store a long time. Even when very old, it doesn't form varnish, just blue goo that easily dissolves in more gas.
This works much better than gas stabilizers, which I don't think much of. The 100 octane is unnecessary but harmless. You might expect harder starting due to its slightly lower volatility, but I haven't noticed, even in snowblowers here in PA winters.
I just mention the avgas because ethanol makes unused carbs dirty even faster than auto gas did before ethanol was added, which was bad enough!
