I read a study once where it was concluded that there is an unexplained (at least at the time of the study) spike (INCREASE) in wear on the engine immediately following EVERY
oil change. Then the "wear rate" would return to the pre-
oil change rate very quickly. This was true even though the new filter(s) were filled with new
oil etc. (i.e., not a result of a "dry" start). Sorry I can't find the study now.
Appreciate all the input and opinions.
