if any of uuuuu, ever get the opportunity to take a carb apart,,thats had eth sitting in it a bit toooo long..youll never run that garbage again.......................................
EXCELENT post!!! What anyone want's for storage is plastic like HDPE. It is one of the major fuel resistent plastic's out there. Further from a molecular level, highly apolar so that it is "absolutely" impervious to air born water. So just turn over your fuel container and check. All plastics have the type of plastic molded into the form.I think one of the often overlooked things that cause problems is what people store their fuel in - and this can be made worse by ethanol. I know lots of people who store fuel in various old plastic bottles rather than actual fuel jugs, and these plastics can leach out into the fuel and leave deposits in the carb.
I can't say for sure it helps but I figure it's cheap insurance...it only takes a little glug per gallon. I believe it is supposed to help minimize fuel acidification and phase separation. And it has some type of enzyme that is supposed to help break up varnish and deposits. It sounds good on paper, how well it really works is hard to say.

What is interesting is that I also use a lot of Echo 2-cycle mix, and nothing but E10, and I often keep my mix longer than month - I never have goo in my carbs. They all seem to be whistle clean when I pull them apart.Every carb I have rebuilt in the last few month had "goo" in it. I put Stabil Marine in all the gas I use in the mower and my Echo 2 cycle mix has the stabilizer in it. I go through about 4-5 gallons of a gas a week in the mower so it never really sits around. My 2 cycle plastic gas container sits around for maybe a month before I've gone through it all. My biggest fear is if I don't take the motorcycle out for a few weeks. I hate rebuilding those carbs.
Another good point is I only use high traffic gas stations. That way I know the gas is not just sitting....
Aquired brand new or used? That is clearly a problem in this discussion that many commenters are mixing experience levels and often relaying their quality standards to the standards of others. So if I buy a used saw from someone who has no idea and no interest in careing for his equipment and experiencing some time down the road problems, well I shouldn't be suprised and blame something that just appears at the moment an easy scapegoat.What I meant was all 2 cycle stuff I have acquired had goo in carbs....
That fuel stored at the distribter is unmixed has actually quite a simple answer. It actually has NOTHING to do with ethanol. It has to do with the fact that irrespective of distributer brand ALL local gas stations, irrespective of brand name, are getting their delivery from this single distributer. And ALL brand name have different additives added to their fuel which claim that their fuel is the "best". These additive packeges are added when the fuel tanker is filled so that each brand is "special".Here is a little fact, Federal regulations state that no ethanol mixed fuel can be stored in any fuel distrubition tank/fuel dealer.
Ethanol can only be added/mixed with fuel as it is loaded into a fuel tanker that will then deliver it to a gas station/end seller that day.
Where do you have this information from? I can't find this type of information on any homepage of any fuel company, goverment site or any other based on scientific research.After delivery the E10 has a shelf life of 30 days
Is ethanol that bad?
Yes, for the following reasons:
1) Ethanol does not explode like gasoline does, it does not have the same stoichiometric properties as gasoline.
2) I have read that 10% ethanol equates to leaning out of fuel to air mixture by about 4%. What a complete waste of volume for a substance that confers absolutely zero benefit to the performance of an engine. This volume of fluid that is leaning out your mixture would be infinitely better off as 2 cycle oil (obviously not at 10%, maximum of say, 4% oil).
3) Ethanol is hygroscopic/hydrophilic.
4) Can certain additives be added to gas to neutralize the detrimental effects? There's a ton of them that claim to, and some probably do work, however no additive on Earth can negate the fact that you still have 10% (or more) of volume of a fluid that is taking up space that could otherwise be used my more oil (within reason obviously) which would increase power and engine longevity.
5) Ethanol attacks rubber gaskets and fuel lines. This can be mitigated, but I didn't get to vote on not having ethanol in 99% of the pump gas in my state, so I'll "vote with my wallet" and pony up for something like Trufuel, or I'll go the cheaper router and use 100ll from my local airport even though it's not optimal like the aforementioned, or VP Racing, et.al.
6) There's an official document that is sternly warning about the appearance of E-15 with respect to 2 strokes--within a matter of minutes, a 2 stroke engine literally blew apart when run on E-15. Also, on motor vehicles that got along fine with E-10, E-15 causes engine damage in some 4 cycle automobile engines. Do the big-agribiz lobbyists care? Nope, from their point of view, you can go pound sand, it's "your problem".
No, it's in there because it's a huge moneymaking scam forced upon the public in the name of helping the environment, which is a lie for multiple reasons.
1. Of course ethanol doesn't explode like gasoline does, that is why gasoline is the main property of the mix.
Guess what, a lot of equipment (i.e. landscaping outdoor power equipment) nowadays have carbs that are completely non-adjustable because of the fascist EPA. And when I say non-adjustable, there are no hidden carb adjustments to defeat, there is nothing you can pry open or grind out to reveal anything.2. But if someone doesn't have his carb adjusted to the type of fuel he uses or the elevation level he is at, well then their is no one nor anything like ethanol, etc. to fault for having a saw burn up...
It's absorbing water molecules right out of the atmosphere the moment you are pumping it into a container. The point is, there's no benefit to having something added to gas that has an undesirable chemical property that non-ethanol gas does not have.3. Ethanol is hygroscopic. So what does this tell us? Of course we all have our fuel stored in "air tight" HDPE fuel containers. So one cubic yard of air contains at ambient temperatures a few drops of water. Further we all know that HDPE plastic is about impermeable to water. So for water to contaminate our fuel mix, where does it come from...
You didn't read my post thoroughly and instead reacted in a knee-jerk fashion:4. Clearly you are not serious about exchanging oil against ethanol. That is clearly a very unwise thing to do because going over a certain level you easily decrease your engine power and increase carbon build up. Just to be sure you understand the mathematics, all manufacturers recomend a mix of 1:50, that equates to 2% two stroke oil in the mix! Going to your 10% that would equate to 1:10 mix...
If you think 2% of a real, quality synthetic 2 cycle oil (such as Mobil 1 Racing 2T) will result in less carbon buildup and more power than 32:1 or 25:1, you are sadly mistaken, and that's not my opinion, it's a fact.This volume of fluid that is leaning out your mixture would be infinitely better off as 2 cycle oil (obviously not at 10%, maximum of say, 4% oil).
You'd really love to see it eh? Here you go:6. I would really love to see this document! And this stupid statement clearly shows how little knowledge and so much paranoia are present in this topic!
^ I guess the above are all "paranoid!" because you said so, obviously you're more of an authority."It is clear that millions of Americans are unfamiliar with E15, which means there is a strong possibility that many may improperly fill up using this gasoline and damage their vehicle," AAA President and CEO Robert Darbelnet tells USA TODAY. "Bringing E15 to the market without adequate safeguards does not responsibly meet the needs of consumers."
BMW, Chrysler, Nissan, Toyota and VW have said their warranties will not cover fuel-related claims caused by E15. Ford, Honda, Kia, Mercedes-Benz and Volvo have said E15 use will void warranties, says Darbelnet, citing potential corrosive damage to fuel lines, gaskets and other engine components.
