In Reply to: Mobil's reply sounds like a sales pitch posted by Robert on September 29, 1998 at 09:58:12:
I am not convinced that the Mobil position is incorrect. Several thoughts:
1. Although people commonly say that petrolium based lubricant is better for a new engine ("... to facilitate ring seating..." etc.), I have never seen a good description of the mechanism whereby this occurs. What are the properties of petrolium based lubricants that make this so?
2. I believe the Redline position is a marketing position. Since engine infant mortality is a potential issue, having someone else's oil in an engine initially reduces the possibility of being associated with an early failure.
3. It is not at all obvious to me that the Mobil position is a sales pitch. If so, it has merit only if argued to manufacturers, not individual customers. Even at that, it seems inconsistent with the advertised extended change periods.
4. The fact that some good manufacturers are initially filling with synthetic seems to me to be persuasive in the absence of science or statistics to the contrary.
