STIHL 2 Stroke Premix

I used it for two years trouble free.

Then started mixing my fuel own because of cost. 

The first batches I made used E-10 and that is when the problems started. 

Same mix I used in other brands of equipment without issue. 

That is when I found that the alcohol was killing the diaphragms.

Carburetors were not gumming up. The diaphragm just dissolved.

This is not a shelf life issue. It's a chemical compatibility issue.  

Switched to alcohol free fuel THEN switched from STIHL oil to AMSOIL

Solved the carburetor issues and cut cost 75%

Don't have to buy new equipment

 

There is nothing wrong with STIHL fuel except it cost over $35 a gallon. 

 

Want to pour your money down a rat hole? Have at.

I shared this for people that were looking for a fix that didn't include the budget of a small nation to cure. 

I shared this for people who wished not to toss otherwise good equipment to go four stroke or battery. 

 

Yea I toss my $300 machine to buy another machine so I don't have to mix my own fuel and save money. 

I don't have to understand it. It isn't my money.  Hey, do whatever you like. 

 

 

 

I mean i paid 28 bucks for a case which has 4 of those containers in it. They last me around 2 1/2 - 3 years worth of use, not worth my time doing it any other way.

 

I can understand though if you are a landscaping business or someone who uses a good deal of it, but they also use their equipment daily so it is less damaging to use treated ethanol added fuel imo as it doesn't sit in place mucking everything up.

You got 4 one gallon containers or four quart containers for $28 of STIHL fuel.

So the other day I was watching some tube and saw a way to cut a lemon for juice that eliminated all the seeds and recovered more juice and this is how it was done Bla...bla....bla.... works really well!!  

 

1st reply: 

 

I've been juicing apples for fifty years and never had an issue with seeds.

Besides I only juice about once a decade. 

 

2nd reply:

 

Why don't you just buy plastic fruit and quit worrying about the seeds.

 

3rd reply: 

 

I saw that and that guy is an idiot. I wouldn't believe a word he says. 

 

4th reply:

 

Com'on man everyone knows organic is better. Skip the plastic stuff.

Quart, i only have a gas powered leaf blower that i use it in so like i said that stuff last me a good while. I would without a doubt ruin it if i tried to use pump fuel, i can not get non ethanol blended fuel in my state so the stuff is pure evil to any small engine.

That is a great price!

I call BS on the fact that 10% ethanol blend pump gas ruins Stihl equipment. I have been using Stihl Ultra 2 stroke mix with pump gas and Stabil for years in my chain saws and string trimmers with no ill effects, don't drain tanks at end of season either. The ones that are probably having problems are not running any type of fuel treatment and letting the equipment set for long periods of time.

Your prerogative. 

 

I can't run my 65 Ford with 11:1 compression on 87 octane but it doesn't bother my 2015 Ecoboost. How old is your equipment and how old is mine? Those would be good questions to ask beforehand. Change happens with time and model. Believe as you wish. I know what I did and didn't do and what the results were.

I can run old and new vehicles and snow and lawn equipment with 10% ethanol in the fuel just fine, I don't see any difference in the short term.  Long term though the ethanol does damage the fuel lines in the lawn/snow equipment and fouls the carbs.  That is why I use STABIL-360 to treat the fuel containing ethanol I use in my equipment if I can't conveniently fill my fuel cans up with non-ethanol fuel.  The STABIL-360 has an additive that eliminates or reduces the ethanol issue while stabilizing at the same time.  I've run 2 year old gas that I treated with STABIL-360 when I filled those cans up, and it worked fine.

One other product to help with Ethanol is AMSOIL's Quickshot®

I did an outside visit with my mother Saturday and spent time with my brother. He has about 19 crews he runs with his son. That’s a lot of chainsaws and weed eaters. About 3 each per crew. He has quite a supply at his shop some 40 years old. He has the last 3 lawn mowers I discarded. He like to tinker. I ask him about fuel problems. He showed me his stash of carburetors. They’re pretty good at changing them out. Seems to be a common problem. They can’t get straight gas routinely. I told him the Grumpy mixture. He’s giving it a shot on some crews to see how it works. Doesn’t change how I would do it as a limited use 2 stroke application. My brother even uses the can stuff on limited use equipment. So the degrading effects of fuel is a problem commercially for 2 stroke tools. Until industry is forced to fix it by competition, why would they? It’s a money maker.

I run lots of 2 cycle race engines in RC model boats. Ethanol fuel will kill your carb in as little as 30 days. You might get lucky with a couple years but it will get the rubber flap valves and diaphragm’s of common Walbro or Zara carbs.

I’ve been running 100 low lead aviation fuel with Quicksilver oil. The ratio I run in the marine race motors is 8 ounces to a gallon. Those see sustained 18,0000 RPM. In my lawn gear I reduce the oil to 4 ounces a gallon. I’ve got both an edger, trimmer, and blower pushing 15 years with carb changes at the 10 year mark. If you want long life and low maintenance use the can fuel or if you use a lot try the 100LL.

So your point is you agree the alcohol kills the diaphragms. Not gum it up but kills the rubber. Great we agree on that. 

You then say you mix your own alcohol free fuel and have also experienced little to no trouble. Great, we agree again. 

Everyone that has used the alcohol free fuel has, by it's use, also agreed. 

 

The thing is, the initial post said all of this and gave a recipe for a no alcohol fuel mix which I offered as a lower cost alternative to the expensive canned fuel.

 

Good. You add that 100LL mix and it is available EVERYWHERE and still cheaper than STIHL fuel.  Thank you for that. 

 

People would rather pay 3 to 5 X the cost for something they have already agreed to as the right answer than to say, Yea...that would work. 

 

Of all the petty crap.......

If cost is really an issue you can take a large gallon glass jar of regular ethanol gas and toss in a couple cups of water. Mix it up really well. Now let it sit overnight. The alcohol is hydroscopic and will be attracted and bind with the water. You will see the water at the bottom of the jar after it settles out.

Now take a syphon tube and syphon out the water on the bottom leaving the pure gas. No more ethanol! Now you can mix in your 2 cycle oil and be good to go.

Many of my fellow 2cycle addicts do this when they can’t find ethanol free fuels.

Know this trick but for those that don't...... Some just want to argue about it. $30 a gallon I guess isn't enough reason. Wish I had that kind of money

You know what’s amazing to me? How someone who spends thousands of dollars to change their suspension on their truck. To basically handle like a car. Most every one, me included though that was great. How that same person could fret so much over people spending a little over 5$ every couple years on a can of fuel. I make my own coffee at home. I have members of my own family who go to Starbucks and spend 5$ on coffee. I think it’s foolish. Millions of people do it. I don’t ride their ass about it. Both fuel ideas are good ones and have their place. You’re being ridiculous.
