For winter, how badly do I need to move to SAE0-30 oil from SAE5-30?

I came up with the question by reading my owner's manual. I want to hear from someone familiar with this particular vehicle. If you don't have the actual information I request, then simply don't reply.

That works both ways!.... 14 posted questions for this same vehicle that most of the info should be in the manual... I see you don't like any of the answers you are getting here as a whole, why ask if you just want to complain about it??.... Noted.. >>**(geercom)**<<
