I'm old-school. I drive a car 1500 miles and then do the first oil change.
Then I do the next one at 3000 miles, and every 3-3500 after that.

I also had 3 cars go over 250,000 miles without burning oil.

Five-hundred miles is approx 8 hours. I would prbably go pretty easy for
the first 1,000 miles, secondary roads and short stretches on the highway
around cities. This will do two things; allow the machine to run at
something other than wide open, and force variations in load and speed
like the manual says to do.

It seems I can tell when a car was broken in properly or not. On cars I
had had new, they don't tend to develop 'notches' at certain speeds. By
this I mean, on cars other than ones I bought new, I can notice that the
car seems to hit a stride ~45-50 MPH, and another ~70 MPH. What I assume
is that the person that bought the car new had two driving modes:
secondary roads (45 MPH) and highway (70 MPH). I have noticed this on a
few used cars I have owned.

On cars I bought new and broke in properly, there weren't any 'notches',
everything was fairly even across the range.

You will hit speeds and conditions on any car, no matter how it was broken
in due to engine and mechanical efficiencies. On most 4 cylinder Toyotas I
have owned, they seem to hit their stride 70~75 MPH, since I assume this
is the engine's most efficient mode. I have noticed this on 4 or 5 Toyotas
I have owned. Always got the best economy at about 72 MPH in 5th gear.

Of course, with newer cars and a V6, things are different now, but I would
still take it pretty easy for the first 1500 miles, and stop and have the
oil changed.

How do you know that the speeds that the cars were driven at had
anything to do with these "strides"? And why would driving a car a
particular speed cause this?

I think you don't know what you're talking about.

From the owner's manual for a 2008 Pilot:

"Help assure your vehicle’s future
reliability and performance by paying
extra attention to how you drive
during the first 600 miles (1,000 km).
During this period:
Avoid full-throttle starts and rapid
acceleration.
Do not change the oil until the
scheduled maintenance time.
Avoid hard braking for the first
200 miles (300 km).
Do not tow a trailer.
You should also follow these
recommendations with an
overhauled or exchanged engine, or
when the brakes are replaced."

Note what the manual says about the first oil change.

what??? read the manual??? no freakin' chance buddy! we're all going
to have a retardation contest here on usenet and take the words of
nameless idiots with our new multi-thousand dollar investments, not the
experts that researched, designed and manufactured the freakin' thing!

imagine these guys in aerospace: "yeah, but this guy said those cracks
didn't matter".

Some people develop superstitions, and live their lives by those.

Car owners are especially susceptible.

Go by your owner's manual. Things do change over time, and things that
were appropriate back then don't apply now. But you'll never get over
the superstition.

That's in' hilarious. I can just see the NASA engineers hitting up

I think that this is great advice regardless of make of vehicle. It's
how I've always done it. Of course I drive older cars...

The cars I have had new and have broken in myself have not had this
problem. The couple of cars I bought used that do this have a tendancy to
'settle' around 45 and 65 or so. The 7 new cars I broke in didn't do this.
And two of them were identical models.

And my Supra seems to settle around 60. It's a Canadian car, and whne I
say 60 I mean 60 KmH.

But, you never think I know what I'm talking about anyway, so I just
consider the source.

You have had how many cars >230,000 miles?

Feh.


Some things change, some things don't. Rings and cylinder walls are still
about the same as they were 20 years ago.

I think I've probably broken in more new cars than you have.

The manual also probably recommends changing the oil every 7.500 miles
whether it needs it or not.

I've had a half dozen successes with my method, and was trying to pass on
*experience* to the OP. Don't like it? Don't follow it! Simple!

Seven and a half miles? Gee, my mechanic is more than 7.5 miles away.

So was I, which is, follow the manual, not some guy you don't know on
the internet.

It has long been rumored that there are people who are totally clueless
twits who write on the internet.

So which makes more sense: To follow the advice of the people who
actually build the cars or someone who may or may not know what they are
talking about?

"about the same"??? you want to be imprecise so you can claim whatever
you want that way??? or are you saying "about" you don't actually know
the details??? [rhetorical]

it's untrue if you think there are no changes - there are small but
subtle changes to lip profiles that help with power and economy, and
there are improvements to honing processes giving better cylinder wall
finish, and quality.

"success" as defined by "it didn't break down" is not the same as
