Ethanol free gas need stabilizer?

Rkh · Apr 7, 2020

Just paid $2.50 for ethanol free gas for my 3 tractors & small engines. Like to
stock up maybe 10 more gallons-do you have to add stabilizer/sea foam to keep
fresh?

If you're going to use it up over the summer, I'd probably skip it. If there will be some held over the winter, it would probably be a good idea, although my lawn mower started right up on the gas that was in it over the winter.

buy premium gas, no stabilizer needed!

It will be good for a long time.

It's not that ethanol gas goes bad quicker, it's what it leaves behind when it evaporates, and the degrading effect of ethanol on fuel lines and carb components.

If you keep your containers tightly closed, out of the sun, it will last a long time, possibly years.

I know several tractor collectors that use no alcohol gas and store tractors for 5 years without adding anything,alcohol based gas will last about 6-8 months and attracts moisture so I only use it in the summer on my tractors so I can use it up by fall.

I've been using alcohol free gas for a few years now and have never used any stabilizers of any type. My supplier tells me it doesn't need it and on the alcohol free gas there is no winter/summer blend.

I buy only premium for all my tractors and small engines. I was told by my chainsaw dealer that the warranty is void if you use ethanol gas. I used to drain the gas before every winter but I don't now with premium gas and the gas doesn't stink in the Spring and everything starts right up.
Stay safe

I don't use stabilizer in any of my gas, and I use mostly E-10 in all my 4-stroke engines, and don't have any problems. I think we have better than average gas in N MN, should be, we pay more for it!

This guy acts like an idiot. He thinks he is funny, but he is a majority of 1. That being said, I do believe he knows what he is doing when it comes to small engines. If you can stand to watch him, he has some good information.

He started an experiment in January concerning this very subject. He now has a video out for Jan, Feb, Mar, and Apr. I watch them each month.

If you can tell me what fuel stabilizer DOES, exactly, and how it works, I can tell you whether or not you need it.

I have yet to hear an adequate explanation of fuel stabilizer from anyone, including its manufacturers, so I tend to believe it's snake oil.

FWIW, I haven't seen anything that says REC-90 ethanol-free gasoline is seasonally formulated to different vapor pressures than plain old unleaded regular. It may be, but I've never seen it in writing. And it is VAPOR PRESSURE, not ethanol content, that has the greatest effect on gasoline shelf life.

Russ from MN · Apr 7, 2020

I agree with you, he acts like an idiot, looks pretty strange, but that is a good experiment, I hope I can remember to watch the rest of the months! Very detailed and systematic, I was surprised to see how much evaporation, even at the cooler temperatures. I think that's one reason we have less fuel problems up north because we have less evaporation. Makes me want to get an old freezer just to keep my gas in! I have always thought a metal building with no insulation is just a little better than being outside!

Doesn't say not to use E-10 in my new saw manual or string trimmer or leaf blower.

I don't add anything to my E10 pump gas and its just fine for months on end.

when it comes to ethanol laced gasoline, we have opinions, and like other things, we all have one!

Keep buying the Premium gasoline.

But just so you know it to has ethanol in it, up to 10% just like the low octane gasolines.

gregww · Apr 7, 2020

I don't think there is a right or wrong answer to this question. It has been stated by others that there is no scientific proof that additives help or hurt. That being said, I use ethanol free gas in all my mowers. I also add Sea Foam to the gas. It was suggested by my small engine guy and he has been doing small engine work his whole life. It's how he makes a living.

It's kind off like adding food coloring to hummingbird food. Some experts say it is not necessary. Maybe it's not, but I still do it. It makes me feel better. Do whatever makes you feel better. It's not like we're talking hundreds of dollars a year. If you feel better, safer, adding an additive, do it.

If your using ethanol gas in a vented fuel tank system, it helps to use a square of visqueen under the vented tank cap when not in use.

Otherwise the tank is breathing in humid air just sitting there inside or outside while stored.

What make saws?

The owner's manuals for both of my Stihl saws simply say they don't recommend using gasoline with over 10% ethanol, so 10% is all I've ever used. They're both 6-8 years old, and they've always done exactly what they're supposed to do with no complaint.

I have a MTA and 300 Farmalls. They get started once or twice a year. They get about 10 gallons of ethanal every other year. Been that way for 10 years now. No additives or drained tank when put away.

Start with a clean tank and clean gas and be trouble free.

Not is it an ethanol free premium.

FWIW- I tried Stabil once. Left it in a tank over winter. Next spring I had goop in the tank, the entire fuel system was contaminated. I still haven't got that carb working like it used to and it will probably need replacement. I'm not a fan of Stabil.

Well no kidding if non ethanol "Premium" can be found.
I guess it would have to then depend on what octane value your calling premium.
Most states only 92 or high can be labeled premium.
And most everywhere non ethanol gas is REC90 or less.

I can go into town here and buy 102 octane, non ethanol and leaded gasoline. at the pump.
Maybe it can be labeled Super Dooper non ethanol Premium?

I don't know where you're at but here our Premium is non-ethanol. Some stations also have a mid grade non-ethanol and some have the REC90 stuff. Our local corner store gave up selling anything but the mid grade non-ethanol, which I think is 91, because of the large number of people using it in boats and small engines. No one would buy the ethanol when they had it.
