Q. Factory oil additive?

We're all told that the factory, wether it's Honda or Harley put in
this 'special' additive in the engine oil, to help break-in.

I think that's a bunch of crap.

If they did, then wouldn't the dealer offer an option, during the oil
change, to add that fluid back in, especially during the critical
break in (and soon after) period?

Why the hell don't they? Why do the factroy reps, salesmen act so
secretive o is this special oil additive?

To get peopeles' imagination going, I say..

 

Yep! You got it all figured out. No one else could figure this problem out
but you. Congratulations.
You don't work for our President do you?

 

I'm not sure exactly what you are referring to, but historically engines
came with "break-in" oil. I don't know all the details, but I understand it
is low detergent oil that is intended to transport and precipitate the metal
particles from break-in better than normal oil is.

I'm seeing a lot of info (that I haven't quite digested) about modern
engines being designed and built differently in ways that either eliminate
or change the requirements for break-in. The honing process is supposed to
produce a more nearly ready cylinder wall, for example. I expect it varies
by mfr, too.

A brand-new engine has many new, roughly machined surfaces that need to
achieve their final finishes. As they wear in, much jagged metal is
released into the oil.

Break-in oil is very low in dispersants and detergents. The idea is that
the metal mentioned above will settle out of the oil and not risk
recirculating through the engine, causing damage.

Once the break-in period is over (but not before!), that oil is removed and
replaced with normal oil. It is not necessary (or even desirable) to keep
break-in oil in the engine past the initial oil change interval.

After the first oil change interval, the nature of the metal released into
the oil changes dramatically.

 

Actually primarily low /dispersant/ oil.

Dispersants are the chemicals that hold contaminants in suspension until
you change your oil. These are the chemicals that are defeated if you leave
the oil in too long.

 

Buy a new car and it comes free/included.

After the break in period, why would you want more of it?

 

Question?

Where can you buy 'this' break in oil?
