In the DC area I run a 10w30 Mobile 1 year round in my S and have not had a problem. I get a little clatter in the coldest months, but, hey that is when the car is not used much, with all of the salt on the roads. I do connect the battery tender a couple of times each winter if it is not getting driven.
