Do new cars still come with break in oil? Did they ever? I have
always heard that the oil that came with a new car should be changed
I just checked the owners manual of a new Honda and found no special
instructions for the first oil change.
My Subaru's call for first oil change at 3,000 miles and every 7,500
there after. I don't think there is a standard and don't think there is
a "break in oil" per se but during the break in period there is more
metallic particle built up in the oil as the engine parts wear to fit
which would warrant early oil change. Tolerances should be better today
and there should be less wear. Personally, I'd probably make the first
oil change at half the manual recommendation. Can't hurt and may help.
My lawnmower said to do the first oil change at a few hours, but it
has no oil filter to catch any metal shavings left from making it.
Cars have good filters, maybe 70 years ago they didnt. I dont know if
it matters, some even come with Mobil 1 synthetic now new.
It is no longer 1950. The oil in the engine is the same as you'd use at any
time. I tend to change the first time at 4 to 5000 rather than the 7500
normally I use and I do take it easy for the first 1000 miles. I got a new
car last Satuday and I've not gone above 4000 rpm or 75 mph yet, but I only
have 570 miles so far.
In a few weeks I'll wind it up. This new Sonata V-6 has 15HP more than my
old car with the same engine. The rated top speed is 134 mph but the most
I've done was 115 in the old one . Maybe I'll go for it in this one.
If you follow the recommendations of the oil change places and change at
3000 miles, you are wasting money. Unless, of course, you only drive that
many miles a year. Don't belive them that you need the transmission flush
either. Follow the book, not the dealer or Jiffy Lube type of place. They
are interested in making money, not helping you.
I don't know if the auto manufacturers ever recommended that,
but it is a common recommendation.
That is becoming the norm. In your dad's day (that would likely
be my day) they often recommended a short oil change for a new car.
Today engines and oils are a lot different. It is best to check your
owner's manual and follow the instructions given to you by the guys
who really know and are not guessing.
Years ago the factory shipped the cars in with a very light engine oil. You
were instructed to drive the car at a very low speed for X amount of miles
then gradually raise the speed on the car. After a short period of time you
were told to change the oil to a normal viscosity. Reason for this was that
the factory couldn't maintain the close tolerances of engine parts like they
can today. On your first engine oil change on the older cars you could
actually feel metal that wore away mixed in with the oil. In todays cars
the only limitation the factory wants you to maintain is not to make any
jack rabbit starts at the beginning so that all the moving parts can settle
For '70s stuff I was always told just not to stress the engine - there was
no real need to limit peak rpm or speed (within reasonable limits), just
not to put too much load on the engine. I think it was oil change at 500
miles, then another at 1500, then normal cycle after that.
I don't think that's been true on new-from-factory cars for decades,
though (they'll do all the necessary running-in there before delivery,
presumably to avoid the unwary taking delivery of the car and blowing the
engine) - but presumably still applies to modern rebuilt engines.
Yeah - I was used to there being a little magnet in the sump drain plug,
and this'd come out first time with a big column of swarf on it...
Cars in the past came with a special break-in oil - and needed it -
and needed it changed early, but not too early.
Today's engines have much finer finish tollerances and are basically
"broken in" when they are first assembled. VERY little initial wear
occurs - VERY little metal ends up in the oil at the first change..
Current wisdom in regards to break-in procedure is "jump in and drive
it like you stole it"
You've already answered your own question. Why do you ask a question
to this group when you will probably get half of the respondents with
the wrong answer and the other half may just be guessing?
Not that it makes any difference to your situation but my car, not a
Honda, needed its break-in oil changed at 1200 miles. This was not a
ploy to get more money from the buyer because all maintenance for the
first four years, or 50K miles, was included.
Our Constitution needs to be used less as a shield
for the guilty and more as a sword for the victim.
That's probably true for most of the questions asked. It just does a good
to hear the varying range of opinions and the reasons behind them, if there
is one. It's one of the reasons that I come here. No flame intended,
