If I used that philosphy here, I couldn't go to work for 75% of the winter, and hence end up out of a job. Fact of life here, and many other northern parts of North America. And interestingly, 0W-30 isn't as readily available as it should be here.
Phase I winterizing is done for me: winter tires on, snow ice scraper still in the vehicle from last winter, -30F washer fluid in to replace the summer stuff. Phase II will be when it gets colder: replace washer fuild with the -40 de-icing stuff, dangle the block heater plug out of the hood, and chains in trunk if doing a winter road trip.
Everything else, including the 5W-30 synthetic, is kept up year round anyway.
