I've been running stabilizer in all of my power equipment gas all year round for several years now since use can vary so much depending on conditions (long dormant grass periods due to dry and heat, sudden end to snowfall etc...).
Every year on my 1986 Toro 824 despite having a new carb, stabilizer, running dry, lubricating before storage etc... it always needed a disassembly and carb cleaning each fall before the season to run properly. As far as I can tell the Sta-bil resulted in soft deposits, but the whole idea was that there would be no deposits. My Honda summer OPE has stayed clean and functioning well.
Last year I switched to Amsoil AST http://www.amsoil.com/storefront/ast.aspx instead of Sta-bil.
I started my snowthrower today on the fourth pull without too much excitement. It runs great and doesn't require any carb work.
This isn't a universal conclusion but, for me, Amsoil AST seems to work better. Any price difference was just made up by better performance.
