OX66 O2 sensors and winterization

[fondafj]

Should the O2 sensor be cleaned after fogging the engine for winterization? Will the oil contaminate the sensor and shorten the life if not cleaned?

Good Question. I hope Rodbolt chimes in here. I've always gone real light on the fogging oil on Cylinder #1 since I was concerned with the O2 sensor getting all crudded up.

Thanks,<br /> Dewinterizing time sounds logical - after firing up and running the oil deposits out of the cylinders.
