Ethanol Free gas

[stihltech]

Here we go again.If you want to store your fuel a long time, get the non ethanol IF there is no water in it when you get it. Many a saw comes in with the words "only run non ethanol" and find water in it. The last one was 1/4 tank.
Myself, regular ethanol fuel, put in an additive of you choice and use it up in 90 days.
Also, empty the fuel can before mixing the next batch (water will be in the bottom).
Again, a quart glass jar is one of my most used tools. And ANYBODY can use it!
Maters-commence!

All we get here in Canada is ethanol fuel now. Never an issue when treated before storage. For me, Seafoam in everything other than my vehicles and Sta-BIL before storage. I run the equipment then shut the fuel off if equipped until it quits.

I just replaced the carb on a generator that had E10 and was not run dry over the Summer. A fuel shut-off solenoid on the bottom of the bowl was corroded from water. The fuel also smelled pretty bad. I've seen metal fuel tanks rusted from E10 left in them over the Winter. I had Rec90 in my boat that sat for 1.5 years. I siphoned out about 20 gals and it still smelled good. I put it in my truck a couple gals at a time and had no problem. Didn't risk running it in the boat because of octane loss concern. I run Rec 90 in all my saws and yard equipment.

Pure gas in all outdoor equipment.From '46 2N Ford to '81 372 .Only engines that get ethanol fuels are modern car/trucks with catalytic converters .If fuel stays in and not run over year- years may have issues .Looked at canned gas the other day ,curious about price ,was scarred by price sticker. Left them for other customers. Glad I have a choice.

Non ethanol for anything that sits for more than a few weeks and alway used for 2 strokes. Ethanol is known to absorb moisture in the same way as dry gas. That why people don’t have issues with water freezing in their fuel tanks nowadays, for the most part, in their automobiles. No hot restart issues on 90 plus degree days due to vapor lock “boiling” fuel like i have experienced with ethanol fuels. Personally i have access to non ethanol fuel at the local Sheetz gas stations, for a minimal increase in price. But the best is 100LL as the mad professor mentioned. The manufacturer states 5 years shelf life, but I’ve know people that stored for much longer with no noticeable change in quality.

Avgas is expensive but it has much smaller amounts of Tetraethyllead in it compared to leaded auto gas along with an anti-deposit additive to prevent fouling. There are no other detergents or aromatics, as they say, which I’ve read are just as bad for our health and are abundant in ethanol and non ethanol pump gas, so its a pick your poison…. Avgas produces better fuel burn and has a higher BTU so you actually get more bang for you buck. Pun intended… 100LL runs about 6-7 dollars a gallon where i am at, so its painful to fill up the fuel bowser but i always have fuel on hand and it doesn’t go bad.

As always everyone has their reasons for what they do. I don’t want to deal with the degradation of any machine/tools parts due to the ethanol. One bad side of 100LL, it seems to swell some Stihl fuel hose, not all Stihl’s, but definitely not other brands of saw.
