3,000 sounds about right. The vast majority of people out there do oil
changes every 5,000 miles, the more stringent every 3,000. I'm sure the
dealer meant you can bring it in anytime AFTER you hit 1,000. To do one
only after 1,000 miles is just a waste of oil and way too cautious.

The first service, according to the book, is at 5000 miles. I had them change
mine at about 1000. I'll get it changed again at the 5000 mile mark.

For a new car, I always give it about 1000 miles on the factory fill for
break in.  After that (immediately after that) I fill it with Mobil 1
synthetic oil in the proper viscosity and a quality oil filter (no Fram,
no STP, no Walmart/Napa/Valucraft/etc specials).  Then I do changes
every 5000 miles.

Cheers,

If it were my car, regardless of what they did at the factory, I'd do
this.

Change it at 500, 1000, 2000 and 3000.  A waste?  Hardly.  Oil cannot be
"too clean" and it takes a number of changes to get all the miniscule
metal particles out of the engine.  I myself am skeptical about what is
claimed to have been done at the factory.  I wasn't there.  I am there
with the clean oil.  I did this with my one and only new car, and it ran
just as strongly after 125,000 hard miles as it did after it was broken in.

Wind it up (seriously) a few times while it's still new, on that fresh
oil.  You need to seat the rings, the valves, and spin everything nice
and hard a few times while it's new.  I'm not talking once / day, but I
am talking about taking it close to redline up an on-ramp every now and
then.  It's not bad to do this.  Any engine builder should agree that it
actually helps.

I'm not sure about today's engines, but there was a time when the initial
fill from the factory (in GM cars at least) contained a special type of
'break in' oil.  More likely it was an additive to the oil, regardless, I
know that GM offered the additive as a specific part number to be used when
certain internal engine repairs were made.  Assuming that to still be the
case you should follow the manufactures directions and change when specified
in the owners manual.  Using my own personal experience I would run dino oil
for about 15,000 miles till everything gets seated, then switch to a good
synthetic and change it every 10,000 miles, or annually whichever comes
first.

I know most people will consider what I am saying as abusing the engine,
but keep in mind that I have been doing this to my 17 year old 88GT since I
bought it new, (252,000 miles and still running strong).  I also
successfully ran a rebuilt 78 Trans AM (T/A 6.6) for close to 150,000 miles
this way before selling it to get the 'stang.  Another thing you should
consider, "The more often you mess with something, the more likely you are
to mess it up.".  Do the math, if you change your oil every 3000 miles by
the time you get to 100,000 miles you would have turned that drain plug 33
times, Whereas I have driven 1.5 times that distance already and have only
turned the same screw 25 times.  The fact is, the fewer times you stick your
head under the hood, the fewer opportunities you have to break it.  I'm not
trying to discourage you from working on your car when it's necessary, but
remember, "If it ain't broke, don't fix it.
