That's kind of funny. I used to buy 50 gallon barrels of alcohol free fuel, but I gave it up because I couldn't tell the difference in how my saws ran.
I have no problems running the alcohol infested regular gas. Maybe I'm just not paying enough attention.
I do some work for a couple of tree service guys and commercial landscaping. They come in up at the store I hang around at with the other old farts every morning. One guy has at least ten men working. They fill everything with ethanol fuel since that is all they sell. But, since they are there almost every day you can figure about how fast they go through it.
The only repeated problem I have seen is eventually they will get deposits on the valve stems of those 4 Mix engines and lose compression on the blowers, never the weed eaters which is curious because of same design
I asked why they don't just get a tank at the shop, said it has a way of wandering off.
Anyhow, I don't think they give ethanol a second thought.
