Every where I go I hear this debate concerning Ethenol verses non Ethenol gas. I went for a period of time that I would only run non-Ethenol gas in my equipment. As much as we run it got to be a pain to keep gas plus the extra cost involved.
I had experienced problems a couple of times trying to use the non-Ethenol gas because "I believe" the stations that sell it do not sell sufficient quantities of it to keep fresh gas. Now that is my personal opinion.
There is a local small motors shop that in fact has instructed people to purchase aviation gas to run in their equipment and I understand several people have been doing so. Again for us this was not feasible because of the limited access and the price.
This year I started buying regular gas from the pump. I run it in all of my equipment. Three zero turns, hedge trimmers, weed eaters, chain saw, blowers, generator..............
As of the first of July we have not had one problem I would consider a gas problem on any piece of equipment.
I have tried to make it a rule,that I only buy gas at four different locations. I avoid places like the Walmart gas and Jet Pep..... Not sure what the difference is but even in an automobile theirs does not seem to get the mileage of others. Again that is my opinion.
The reason I use 4 different stations instead of just one is logistics. I do not like to haul large quantities of gas on my trailer. Therefore when we need gas in a certain area we just fill the mowers up and two 5 gallon cans........ Many days we burn over $40 in gas on two mowers.
Hope this helps somebody else.
