Realistically, it doesn't matter. The manual for my 1980s Honda lawn mower says ethanol up to 10% is fine. The engine runs the same regardless, but with premium ethanol free fuel you typically pollute more and you also spend more, as in my area, Premium is typically CA$0.20 or more per Litre. That works out to about CA$.0.80 per gallon more. Gas right now hovers around CA$1.45 per litre (at this time, US$4.29 per gallon) in my Lake Huron town in Ontario, Canada. Also, maintenance falls on the end user. Also, if ethanol supposedly destroys fuel systems, you have to think, rubber fuel hoses and gaskets are made from crude oil, so they will dissolve potentially faster with ethanol free than they do with a mixture of ethanol, a solvent.
Also for storage - after running it dry, spray some engine fogger down the spark plug hole, and crank it a moment to distribute the oil in the cylinder.
A few millilitres of oil works too. In fact, that's what Honda says in its manual to protect the cylinder and since Cub Cadet engines are Honda copies, this applies to them.
This video should be titled, "Starting fluid, the secret ingredient to fire your sparkplug through a concrete block wall. " Starting fluid is an important thing to have available, HOWEVER if we were to equate it to another industry, in a pharmacy, a prescription for Starting fluid would be written on the blue security paper prescription pads, with explicit instructions. As the world is now, is equivalent to a mountain of burnt and bent spoons next to a pile of dirty needles and bungee cords ... I am telling you in no uncertain terms, 99% of the people out there shouldn't be allowed to touch Starting fluid ....
