FWIW, add my vote to the "follow the manual" category--although there's still latitude there. My 560SL manual specifically confines 10W-30 to ambient temps under 50F. Preferred options for 32F up to over 86F, which covers my driving season here in Michigan, are 20W-40, 20W-50 or SAE30. What I've started running is 20W-50 formulated for high-mileage engines, which describes me at 146K. The 10W-30 that somehow got in there at the last change (NOT my idea!) definitely wasn't the ticket for stop-and-go traffic at 70F ambient; loading up with blue smoke from rest, not noted since the change. Guess it's another vote for RTFM.
