karst, the difference in oil was in my ’95 Civic (1.5L) that had about 70,000-80,000 miles on it. I had Mobil 1 5w30 in one winter and the car, on mornings when it was below freezing, sounded like it had a bad rod-knock when I first started it up. The next winter (some 17,000 miles later) I switched to Red Line 5w30 and the noise all but disappeared.
I remember the original formulation of Valvoline Max-Life which had 200+PPM had a similar effect in a friend's car ... but I don't know if the difference was as dramatic.
I don't remember what I used the winter after Red Line ... nor what it sounded like. It was definitely loudest with Mobil 1 ... nearly intolerable. Some of that could be the thinness of the Mobil 1 right out of the bottle.
