Yet another oil temp thread (this one's good...)

Thoughts?

Doubt its an issue of flow, since the factory fill is also a 5w30. The synthetics do flow better in extremely cold but for normal temps, it shouldn't be significant. Someone mentioned its due to break-in, but if it is, it would seem that he would have noticed it more gradually as opposed to right after changing the oil (all else equal). Could you confirm if the temps went down immediately after changing the oil or over time?

Immediately. I drove around last night again and it stayed around 200F. With a bit of "spirited" driving, it went up near 220F, but it does for the most part stay around 200F.

Could be weather related too, temps outside have been a bit lower than before I changed my oil - but, not enough (I would think), to justify the difference.

Also, on break-in, I've got 1356 miles on it as of last night...
