I remember learning that the Chevrolet dealerships were instructed to pour Bon Ami through the carbs of '55 Chevy V-8 engines that blew oil smoke out of the exhaust (smoked) when new. Later on, I saw our local American Motors dealership doing the same thing to 1963, or so, seven main bearing six cylinder inline engines that were slow to break-in the chromed rings that they came with. But that was with completely differently scaled machines, with different fuel lubricity and tolerances.

Fox used to sell Lustrox (might still), which, when mied with castor oil, was used to help break-in some models of their engines. I witnessed two fellows break their Fox engine in and out all in one running session. That convinced me that some things were just worth waiting and working for.

Let me repeat. I AM NOT an engine expert. I do have lots of experience and some chiseled in stone opinions, but don't do as I say. Guiding the layman thusly is the job of the manufacturer, Dar Zeelan and the few MECHANICAL engineers (no, software engineers don't count) that inhabit this forum.
