MIne is at 60 during warm up on 351w with 178K miles. After getting a mechanical guage I quickly went from 20w-50 to 10w-30. I go with the thoughts that thinner is better during warm up so oil gets through the filter (not bypassed into the pan) to the bearings. If I could find Mobil clean high mileage in 5w-30 I would use it in mine.
