I never got in that 2 stroke, 4 stroke "oil" thing. I just watched.
For the purposes of "winterizing" that is really more of a 2 stroke
thing since a 4 stroke has a sealed crank case. I have still heard of
shooting in fogging oil but I am not sure why. If you do anything, you
pull the plugs and squirt some oil in each cylinder, spin it over a
few times, reinstall the plugs and expect a smoky start.
More important is to drain the gas from the VST or carb bowls.
E-tec sells an auto winterizing feature that basically shuts down the
ignition, while it maxes out the oil injector and you get a dose of
very rich fuel while it is cranking down. (Basically like fogging
until it stalls)
That still does not address the fuel gelling in the system.
It was your comment to be sure and use 2 stroke oil that got Donnie started on the whole thing. At
the time you thought my Yamaha was a 2 stroke.
