I always use stabil in the 2-cycle mix.
I keep at least two cans of gas on hand for four cycle engines. One can is normally fresh and used for equipment where I expect to refuel in less than a month. The other is always stabilized, and it is used to fuel rarely used equipment (generator, chipper, ...). In the fall I usually put stabil into both so that all the equipment has stabilized fuel thru-out, in case I don't use it again until spring.
Works great. No problems since I started doing this (10 years ago?).
Oh, and I'm in a very dry climate. (SW Idaho, ~ 12in annual precip which comes mostly october to april).
