Ethanol free

[C-dub]

I've thought about "making" my own ethanol free gas for my mower and Stihl multitool motor. It's not difficult to do, but some equipment would make it so simple. I'm sure some of our chemists here can confirm this. I'm considering getting a separatory funnel and stand to do this. Since ethanol attracts water all one needs to do is mix in a cup or more of water to a half gallon of E-10 or E15 gas, shake to mix well, then just let it sit for several hours. The heavier water/ethanol mix will settle to the bottom, while the nearly pure lighter gasoline will remain at the top. Then, in my plan, I would just let the water/ethanol mix out the bottom of the separatory funnel until only the gasoline remained. There would be an easily visible line of separation. The only thing holding me up at this time is what to do with the water/ethanol mixture. It is still flammable and I don't know how I would get rid of it yet.

30 years ago we would have poured it on fire ant mounds.

Yeah and I think I still have some malathion around here somewhere.

If you use enough water to dilute the alcohol, the mixture would not be flammable.

Ethanol-free gas is the only gas I run in my three lawnmowers. Good stuff.
Several lawn-mower mechanics recommend it too, especially if your lawn-mowers "sit" over the winter.
They start right back up in the Spring when I leave ethanol-free gas in them over the winter. Not so much with ethanol gas--something about the ethanol separating over time and doing bad stuff to the carburetors. Costs more but well-worth it.

Yeah the ethanol likes to bind with water. So over time it'll bind with moisture in the air. Gas will go bad on its own, we didn't need to put stuff in it to make it do it faster. It is why I buy the canisters of pre-mix for me weedeater and chainsaw because it was ethanol free and I don't use enough to need to mix big batches where cost comes more into it.

Hmmm, I still don't think I could just pour it down the sink or flush it though.

Well you could. But then you would be drinking it in a month or so after it cycled through the water treatment plant.

How much more do the gas stations charge for ethanol free gasoline? I doubt we'd see that type of fuel in Harris County because I believe we are an ozone-nonattainment area.

Buckee's in Katy is about $1 more per gallon.

IMHO, some of you guys have your priorities all screwed up. Looking for a gas station that is Ethanol free? That is not how to choose a gas station. For me it depends on the time of day. Morning fill up? Who has the best coffee? Mid day fill up? Which place has the best hot dogs. Late afternoon? Who sells beer the cheapest.

^^^As a father of three young kids, mine is who has the cleanest restrooms. Buc-ees always wins that one, and full length stall doors to combat the nosey types.

I think most are selecting ethanol free for small engines, not where to go for normal stops. That's all i use it for.
I'm not paying the premium for ethanol free on the car with fuel injection.

I'm liable to do that tomorrow and drop a match on top. Some might be surprised how long a fire ant mound will burn. Can't be fire ants without being on fire. Don't know if it works to get rid of them but it makes me feel better.

Waco Walmart on Franklin has 87 ethanol free.

Putting ethanol in gasoline is the biggest fraud perpetrated on us by the agri-business industry and should be stopped.

[puma guy]

FYI the new Buc-ee's in Ennis has ethanol-free gas.

Thank you for the tip!

Bill, the Bucee's in League City and on I-45 both have ethanol free gasoline.

Gasoline is a complex blend of many petroleum constituents, plus additives and goes through an extensive QA process for many qualities. I'd check the octane and other qualities before using it especially in a car. Probably simpler to by ethanol free gas. I've read of using aviation gas mixed with regular, but that would be a tedious project with out access to a research and motor octane engine. Also, while I'm not a pilot, I believe the fuel air mixture for plane engines is different than mogas engines. Jets and turbo prop engine use Jet fuel (basically high quality kerosene) so don't confuse it with avgas for cylinder engines.
