Fogging MPI engines with cool fuel

In the past I've just sprayed
fogging oil into the throttle body
when winterizing.

I heard somewhere that you can
remove the water separator/ fuel filter
and pour some 2 cycle oil into it, then
reinstall and run til it starts smoking.

Anybody heard this ?

I remember on the VST engines,
the service manual said to add
2 cycle oil to VST for fogging.

I like the oil in the gas but pour some Fuel Stabilizer in the tank and run it through the engine before shutting it off for the winter. The fogging works great through the throttle valve on an EFI.

That's the only way to do it. Spraying oil into the throttle body will mess of the MAF and MAP sensors.

Does MAF refer to mass airflow sensor? These are speed density systems.
