Outdoor Power Equipment (Lawn Mowers, Snow Blowers, Chain Saws and more) Discussions

I recently purchased a snow thrower.  The person who delivered it recommended that I always add stabilizer and fuel dryer/antifreeze every time I fill the tank.  He made it very clear that while many are ethanol, I should use isopropyl dryers/ antifreeze.  Considering that we can have light and heavy snowfall years in central NJ, I understand why I should always add stabilizer and dryer.  One can never know if they will use up the fuel in the tank.  What I don’t understand is why isopropyl over ethanol.   While I have only shopped at two places, I have yet to find a dryer with isopropyl.  This guy also repaired engines.  Does he have a valid point and should I search longer for the isopropyl?
