I brought this up in the Lawnmower forum, so you guys from there, please bear with me; there may be some guys with chiansaws who haven't discussed this.

I talked with my dealer about gasoline and he told me basically, any 2-stroke engine and anything with a carbruator should NOT use ethanol formulated gasoline. It's fine in your modern fuel injected automobile, but your 2 stroke chainsaws and string trimmers and most lawnmower engines will be adversly affected in the long run. I used ethanol last year and I havn't noticed any problems, but I switched to straight unleaded this year. I figure the extra 1.00 I spend on 5 gallons of gas is worth the peace of mind.

I think I have seen a slight difference, not sure because I try not to buy gas with corn in it. When I have had trouble, it seems to be in my Weedeaters, but they are junk anyways. Not going to buy Corn gas if I can help it. :eek:

there is only one or two stations around here that have ethanol and i don't go to either and thankfully i never have problems with bad gas although gas never sits around that long i go through a bunch of gas in my mowers, tractors, and power equip something like 10 gallons a month.

Around here,they all claim to have ; up to 10 percent ethanol. And over half of the equipment I get in, is usually due to a rotted fuel line or carburator related problems. Some have bin less than 16 months old.
I really need to get me one of those ethanol test kits.

From what I gathered is; ethanol has an adverse affect on the 2-stroke mix oil. Another words, it doesn't let it lubricate the bearings as intended. And it attacks the rubber/plastic in the fuel system.

Maybe someone else can elaborate on this, that has the facts?:confused:


As for now, I've had no problems with my personal saws, trimmers or mowers. But mine see regular use, I don't know if thats a factor or not. I run a synthetic mix and 93+ octane at 40:1, in all my 2-stroke equipment. Some call for more and some less, but I've never had a failure on this ratio/mix.;)

I'm using the Sta-Bil blue marine formula. It is more concentrated than the red formula and they state that not only is it a fuel stabilizer but also an ethanol treatment. You can find it now in the small bottles for around 9 bucks at Wal-Mart. Treats 80 gallons!

oddly enough the only thing i have had trouble with so far was my tractor today it has sat about a month with what i believe is e85 gas in it and it was having troubles running when i decided to fire it up and drive it around the yard. but go figure all my 2 cycle stuff can sit for 6 months with the crap gas in them and will fire up with no problems

I have found several places here that doesn't sell ethanol in their gas, so I should be okay. Would like to buy it in Missouri, where gas is 10-15 cents cheaper(6 miles away)but all of Missouri gas has ethanol and they don't have to mark the pumps. So Kansas gas it is for me.

I'm in NJ where ethanol-mixed gasoline is in every gas station in the state, so I'm stuck with using the mix in my 2-cycle equipment. So far, the only ones that have been affected are two of my chain saws. One had the plastic fuel line almost disintegrate. When I started to remove the line, it was in 6 short pieces. The carb in the other had to be rebuilt, so that meant buying kit over the Internet. I guess having to do such repairs is a fact of life today. I've gotten into the habit of draining the tank on my string trimmer, chain saws, blowers and mini-tiller if I know I'll not be using the machine for a few weeks or more. Not sure it will do much good, but that's about the best I can think of.

As you can imagine, I'm very much opposed to this ethanol plague, and I don't believe it's necessary. I've read somewhere that it has driven the cost of gasoline up about 50 cents a gallon and causes unnecessary mechanical problems.

I used to use the red Stabil but now have switched to the Stabil Marine blue formula which is supposed to treat ethanol. So far no problems but then I never had any problems using the red Stabil either
