This is interesting. I understand how running the oil at lower temps can be beneficial due in part to its thicker viscosity. Over the year or so that I've been here, that concept has been brought up with the idea that running an engine colder, such as when doing short trips, actually affords better protection.
So, with oil running cooler for better protection, might it also be true that cooler oil temps prevent the oil from getting hot enough to burn off water, gasses, and other contaminants which, in turn, degrades the effectiveness of the oil and reduces its long-term viability and making 10,000-mile OCIs problematical? Any thoughts on this, any experience with the issue ... or is it even a consideration?
