Can you tech / mechanical guru types please tell us about what exactly is going on with the MO's engine and trannie during the "break in schedule"?
I noticed that the manual says not to drive over 4,000 rpm, don't accelerate at full throttle, avoid quick starts, avoid hard braking, and no trailer towing for first 500 miles.
Over the years of owning several new cars, I can recall people saying that the break in period allows the insides of the engine to smoothen the still "rough edges" of the machined internal moving parts. It also avoids placing excessive stress on the various parts like cams, valves, cylinders, gaskets, etc., until such time that the engine has become "seasoned" to hold up under high rpm, fast braking, towing heavy loads and other high stress conditions. All this was hearsay from non-mechanics.
What is fact and what is fiction here? Thanks in advance!
