On another forum, several people told me that I had to change my oil at 500 miles. I have a new 2003 Accord Coupe V6 and the manual recommends only the standard interval for the first oil change.
Also I want to go M1 synthetic and the recommended grade is 5W-20. Do they have that yet or am I ok with 0W20?
New car first oil change at 500 miles - necessary???

I never go past 500 miles on a new engine with the original factory fill.
Rebuilds are a different matter.
If this is a warranty issue, I'd go with the Amsoil XL 5W20 at 5k intervals. If the owners manual allows 5W30, I'd go with M1 5W30 or Schaeffer's 5W30 blend.

When you say rebuilds are a different matter, what do you mean MoleKule?
Honda uses a special break-in oil which reportedly has 1,000ppm of moly in it. They want new owners to leave this in for at least the first 5,000 miles.
If it were my car, I'd probably follow that advice ... or some interval close to it. Maybe I'd swap out the filter halfway through that interval to get rid of some of the initial shrapnel. ![[I dont know]](/forums/graemlins/dunno.gif)
Then top off the crankcase with a moly-equipped oil. ![[Smile]](images/icons/smile.gif)

--- Bror JaceWhat Bror said. Read your owners manual carefully and stick by their advice. Acura's website has more information on the subject under the owner's link.

I vote with the early-out crowd. I figure, rightly or wrongly, that I'd like to get the early wear metals and leftover build crud out sooner rather than later. Maybe in the end it doesn't really make any difference, but changing early during break-in is what I was taught and I've never had reason to regret the practice for any of the cars I've ever owned - including a '96 Honda Accord.

Regarding rebuilds,
The shops I have dealt with attempt to clean the components as best as possible, but always leave some crud behind.
In addition, I have yet to see machine shops finish and hone as precisely as original engine manufactureres.
I agree with Bror, if you're going to leave the oil in, at least change filter at 500 miles.
Hondas and Acuras ARE a special case and you should definitely leave the factory fill in there for <i>at least</i> 5,000 miles. Bror is right on the money.
quote:Don't worry about the oil filter, Honda/Acura equips their cars with a high quality oil filter which will easy withstand the first 5,000 miles.. even 7,500 miles will be no problem. Rest assured, Honda/Acura has properly set up the car to go 7,500 miles before the first oil change. When you're up for your first oil change, though, try to find a better oil filter than what's sold at the dealer. In North America, Honda oil filters aren't very good. Mobil 1, Amsoil, Purolator Pure One, and AC Delco Ultraguard Gold (discontinued) are examples of good oil filters. see: http://www.ntpog.org/reviews/filters/filters.shtml

Certain engines have moly coated cylinders/rings/pistons etc.
How much moly in the oil is from the oil? How much moly is from the normal break in wear?
Whats does Honda use as antiwear coatings on new engine components?
If moly is used as an antiwear additive, why would you want a high ppm of moly on the breakin oil? Would the motor take forever to break in?
About 1,000ppm of moly is in the break-in oil. Very little, if any, of it is the result of engine wear. See my oil analysis:
http://theoildrop.server101.com/ubb/ultimatebb.php?ubb=get_topic;f=3;t=000159#000006
Break in wear is accomplished by plastic deformation of the asperities (high points) or by instantaneous welding and tearing away of the asperities as the parts move over each other. The former is preferable to the latter since it leaves smooth surfaces that spread the load better and doesn't leave a work-hardened wear particle that can cause more wear. Moly helps ensure that most of the break-in wear is done by mashing the high points down instead of ripping them away.
I read the manual, and while it says nothing about a special "break-in oil", it does specifically say to NOT change the oil until the recommended interval. Considering the only other things it says not to do in the break-in section are to 1.) not start at full throttle and 2.) not stomp on the brakes, i have a feeling this is a pretty legitimate warning. Maybe I'll just leave it in ![[Wink]](images/icons/wink.gif)
Any harm to changing the filter though, as suggested above, or should I just leave that alone too?

Early break-in oil change is like 3,000 mile
oil change interval. It's no longer necessary.
CNC machined parts do not result in big chunks
of wear metal which eat away at the engine.
I don't believe others have answered your
question about viscosity. Do not
use xW-20 oil!! It's only purpose is for
car makers to meet CAFE standards.
Mobil 1 is an excellent choice. For naturally
aspirated engines, HT/HS is not as critical, but
your V6 produces 240hp ![[Eek!]](images/icons/shocked.gif){kind=icon}
I would suggest Mobil 1 0W-40 for that kind
of power.

Ford wants us to use 5W-20 in a 255 hp / 350 ft-lb 5.4L SOHC V8. I would use whatever weight Honda/Acura specifies as they're imports and are "special" For the Ford Modular Motors (N/A that is) I would use M1 0W-30 or 5W-30.

J, are you saying engine "break-in" no longer occurs? ![[Confused]](images/icons/confused.gif)
It may not be as dramatic as it once was, but oil analysis shows higher wear rates for nearly every engine during the first 10K-15K miles.

quote:Metal end caps, for one thing.. The Honda filters in North America either have cardboard end-caps (Fram Canada) or really fuzzy media (Filtech USA). I wouldn't want that fuzz to get stuck in one of those tiny oil passages! Too bad little is known about the 'good' Honda filters, besides the fact that they're only available in Japan..
