Ethanol adversely affects the rubber compounds in the fuel system. I stay away from it in my outdoor equipment.
It's becoming more available as time marches on.
Ohio, Pennsylvania, and New York have a lot of small municipal airports. Even if pure gasoline is 100 miles away I bet you can get Aviation Gasoline from the small airports. It's a slightly premium price but it's available and nowhere near the designer fuel price that you see at WalMart and Home Depot in quart cans.
I'm not advocating TruFuel or the various manufacturers special blends. They're out there and they might be useful to someone in suburbia that uses their chainsaw once or twice a year.
This is a map of reported E0 fuel stations. Higher octane isn't strictly neccesary. It's just how E0 is available here and a lot of other places.
I have watched puregas.org for a number of years.
Closed to me is a marina or airport. I don't consider either "readily available"
If it is not at a local gas station whether at a separate pump of not....it's not readily available.
I will agree the price is much better than the canned gas in stores.
I HATE ethanol but I do this EVERY DAY with small engines and pure gas is nice but just not necessary. Use REAL Tygon stamped fuel line for small ones and you don't even need to use stabil or other good stabilizer all year long on mowers.
One that is clean and running fine will be fine on standard pump gas it is after the off season layup (for the many who have one) that there can/will be problems.
If you simply make sure the last time you use the mower...you DO NOT grab your 5 gal can and see it has 2 inches in it and think "Great! I have just enough to cut my yard with" -----pout that old stuff in your car, go with empty can ans stabilizer to station, pour 1 full ounce for every gallon of gas then get gas, go home and fill up mower, then cut grass, then refill mower and leave until needed next time----and you'll be just as good as using pure gas with no additives.
I wish I had local gas station ethanol free fuel but I am not going to inconvenience myself when plain old pink stabil gets the job done.
Note: never buy at parts store.
Here it is 13.99 at local auto part stores. Walmart 8.88, Meijer 8.99-9.99, Rural King 8.99-9.99 sale dependent for quart bottles.
