Re: What is your opinion on MotoMan's Break In Procedure?
Although everything people are saying in this thread sounds knowledgeable and backed by some facts, I just cant for the life of me picture myself doing 5 WOT runs in a row with like 6 miles on the ODO. First off it is VERY critical as woosch stated that the transmission and differentials are worn in correctly. And I can assure you that 5 sustained WOT runs 1st through 3rd will be assuring everything BUT proper break in for those. To be honest I would rather have my tranny and differentials broke in more properly then my engine. Main reason being is regardless of how a motor is broken in (as per the manual or by the WOT runs), the engine will be reliable for as long as your gonna own the vehicle. That car will be on its 5th owner before any evidence of how that motor was broken in shows up.
You guys can do what you want but when I take delivery of my Overland in a couple months the last thing im gonna be doing is flooring the $hit out of it. Im going to drive relatively easily with VARYING RPM's (that to me is whats key). Always ensure fluids get up to proper operating temp before doing anything crazy.
