5 Things You Should Never Do In A Brand New Car

Transcript

Hello everyone and welcome. In this video
00:01
we’re gonna be talking about five things
00:03
which you should never do in a brand-new
00:05
car. Now the definition of brand-new,
00:07
of course, will change depending on the
00:09
vehicle, but generally we’re going to be
00:11
talking about the first thousand miles
00:12
of which you’re going to be breaking in
00:14
your vehicle, so check your owner’s manual
00:15
it’ll tell you you know what that
00:17
break-in period is but we’re gonna be
00:19
talking about five things which you
00:20
shouldn’t be doing during that time.
00:22
Now I think it goes without saying, but I’m
00:24
going to say it anyways:
00:25
In the event of an emergency, ignore
00:27
everything in this video and just do
00:29
whatever you need to do to be safe.
00:30
Like I said, I think it goes without
00:32
saying, but some people out there may
00:34
value their car over their own life you
00:35
shouldn’t do that you should value your
00:37
own life. So you know the biggest things
00:39
we’re going to get into of course have to
00:41
relate to the engine and these are going
00:43
to get somewhat controversial, but you
00:44
know, one of the biggest things about
00:46
breaking in a new vehicle is breaking in
00:48
the engine and making sure that these
00:50
piston rings seat properly on your
00:52
cylinder wall so on your cylinder wall
00:54
you know you’ve got that freshly honed
00:56
cylinder bore and you want to make sure
00:58
you get a nice seal between that and
00:59
these piston rings. Now these piston
01:01
rings have some spring tension in them
01:03
which allow them to expand out and rub
01:05
against that cylinder wall but that’s
01:07
not really what’s going to be doing the
01:08
majority of wearing in this piston ring
01:10
on that cylinder wall. Really, you’ve got
01:12
the combustion process occurring on top of it.
01:14
Those gases are going to pass in here,
01:16
they’re going to get in these gaps, get
01:18
behind the piston ring, and force that
01:20
piston ring out, and expand it out on
01:22
that cylinder wall, and that pressure is
01:24
what’s going to wear down that cylinder
01:25
bore. Now you don’t need an excessive
01:27
amount of pressure to do this and this
01:29
is where it gets kind of controversial
01:31
so points 1 and 2: Don’t floor it and
01:34
point 2: Don’t bring it all the way up to
01:35
you know red line to your highest RPM,
01:38
and you know there’s certainly people
01:39
out there will say a hard break-in is necessary.
01:42
We’re going to talk about you know kind
01:43
of why that’s not true based on all the
01:45
data that’s out there based on all the
01:46
information that’s out there and based
01:48
on what all the manufacturers out there
01:50
recommend and so basically what you’re
01:52
doing, like I said, you’re sealing these
01:54
piston rings up against that cylinder
01:55
bore and wearing it down to have a nice
01:57
seal. Now you don’t want to do this too
02:00
fast and with too much pressure.
02:01
There’s no reason. You can cause damage.
02:03
If there are imperfections, you’re going
02:05
to wear down those inf–
02:06
imperfections too quickly and that could
02:08
cause hot spots which could cause
02:09
problems.
02:10
So you want a nice gradual wear of that
02:12
cylinder bore with
02:13
these piston rings so that you create
02:14
that good seal and some people out there
02:16
will say you know for performance if you
02:18
want maximum power you need to floor it, you
02:19
get that perfect seal, and the only way to
02:22
do that is with super-high pressure, but
02:23
if you look at performance cars and what
02:25
they recommend this is not what they
02:27
recommend doing so just a few examples
02:29
starting with the Nissan GTR for the
02:31
first 300 miles they recommend not going
02:34
over 50% throttle and they
02:36
recommend not going over 3,500 RPM, and
02:39
that’s for those first 300
02:40
miles and so you know as you can see I
02:43
mean obviously the GTRs performance
02:44
vehicle, obviously they wanted to have
02:46
the performance that you expect from it.
02:48
Why would they recommend that if they
02:49
didn’t you know believe that to be true
02:51
if you know the best method of breaking in that
02:54
engine was with lighter throttle
02:55
applications and without going to super
02:58
high rpm. Another interesting example is
03:01
the new Acura NSX, and one of the cool
03:02
things that they do is they break this
03:04
in from the factory and so they have a
03:06
procedure where they put the equivalent
03:08
of about 150 miles on the
03:09
engine varying the load and not
03:11
exceeding 4000 RPM on the engine and what
03:14
they say this does is that when the
03:15
customer takes delivery of their new NSX
03:17
they can go straight to the track
03:19
because they’ve already put in this
03:20
engine break-in process and so you know
03:23
from the factory the cars good to go you
03:24
can take it out to the track. Now why
03:26
would Acura spend the time and spend
03:28
the money on breaking in an engine
03:30
keeping it under 4,000 RPM varying the
03:33
load if it wasn’t necessary to do for
03:35
the safety and performance of that
03:36
engine? They wouldn’t, it would be a waste
03:38
of time and money like i said and so you
03:40
know these are just another example out
03:42
there of a company which doesn’t break
03:44
in from the factory that’s their
03:45
procedure keep it under 4,000 RPM
03:47
through the equivalent about 150 miles and then let the
03:51
customer thrash it on the track on day 1.
03:53
So a cool thing that they do so you
03:55
don’t have to do the break-in procedure.
03:57
Another example is the Corvette the new
03:59
Corvette the C7 you know they recommend
04:02
and they specifically say for
04:04
performance reasons and you don’t want
04:06
to exceed 4000 RPM and you don’t want to
04:08
do full throttle starts in the new
04:10
Corvette. Basically, in those first 500 miles
04:14
and then they have a separate
04:15
procedure for the next thousand and they
04:17
have you know a total of 1,500 miles of break-in,
04:20
but for those first
04:20
500, keep it below 4000 RPM and don’t
04:24
floor it from a start so you know more
04:25
recommendations out there, these are different
04:27
companies they’re all saying very
04:28
similar things and actually had the
04:31
honor to speak with someone who worked
04:33
in FCA’s performance engine division. They
04:37
actually have their own land speed
04:39
record car where they took a two liter
04:41
out of a Dodge Neon SRT-4 and you know
04:44
boosted that up to, I believe 800 horsepower
04:48
of an absurd amount of boost
04:49
in it and you know they had they were
04:52
telling me they’re break-in procedure
04:53
for that engine with 800 horsepower and
04:55
once again it was varying the load and
04:58
it was changing the RPM, but not going to
05:00
high. I believe the highest he went was
05:01
4,000 RPM, and I asked him, you know, you
05:05
work in this world, you have access to
05:07
this data, you know, is there any
05:08
advantage of a hard break-in, and he said
05:10
absolutely not there’s no advantage to
05:12
it you know it’s just a risk and so it’s
05:15
an unnecessary risk
05:16
you can do a lighter break-in obviously
05:18
don’t baby the vehicle. Give it you know
05:20
decent throttle give it half throttle
05:21
something like that, but you don’t want
05:24
to floor it out because you can run into
05:26
that risk of causing damage if you get
05:28
things in there too hot where these
05:29
imperfections lie. You want to wear them
05:31
down more gradually rather than quickly
05:33
now yes manufacturing tolerances have
05:36
greatly improved and it’s always getting
05:38
better but this doesn’t necessarily
05:39
eliminate the need for break-in period.
05:41
Typically, what it just means is that the
05:43
break-in period will be shorter than
05:45
they previously were as a result of
05:47
better manufacturing tolerances.
05:49
Okay, so we have points 1 and 2: don’t floor
05:52
it, don’t bring it up to redline, and our
05:54
third, we’re going to talk about don’t
05:56
use cruise control and really the reason
05:58
why you don’t want to use cruise control
06:00
is because you want to vary that engine
06:02
rpm as you’re driving and when you set
06:04
cruise control
06:04
you’re just gonna have one set engine
06:06
rpm especially with manual transmission
06:08
vehicles which obviously aren’t going to
06:10
shift for you but basically don’t want
06:12
to use cruise control because you don’t
06:13
want to keep it at a constant speed. You
06:15
want to vary the engine’s load and you
06:17
want to vary the engine’s speed so that it
06:19
gets used to all these varying
06:20
conditions and it properly wears it in
06:22
so you know you can take that into
06:24
consideration and think you know maybe
06:25
you shouldn’t do a thousand mile road
06:27
trip as the first trip in your car
06:29
because you’re probably just gonna be
06:30
sitting on the highway at one set speed
06:32
at one set throttle position at one set
06:35
RPM and so you really want to vary the
06:36
conditions for a proper break-in.
06:38
Moving on to number 4: You want to make sure
06:41
that you avoid short distance travel.
06:43
By short distance travel, what I mean is
06:44
travel that doesn’t let your engine
06:46
fully warm-up. You want to make sure that
06:48
everything gets up to operating
06:49
temperature during all of your trips,
06:51
especially for those first thousand
06:53
miles because you want to make sure that
06:54
you break everything in at operating
06:56
temperature. You want to make sure you
06:57
have proper oil flow, which is only going
06:59
to happen once you get things up to
07:01
operating temperature. You also want to
07:03
make sure that things are expanded to
07:04
their final state so that when they’re
07:06
breaking in, for example, that cylinder
07:07
it’s going to expand out and wear down
07:10
that cylinder wall and so you want to
07:12
make sure it’s at its operating
07:13
temperature so that everything’s in that
07:15
expanded state in its warmest state so you
07:18
get that proper break in.
07:19
Now, that doesn’t mean short distance
07:21
travel as far as like driving around the
07:22
city isn’t going to be good, it’s great
07:24
to do that you know driving around the
07:26
city you vary your engine rpm, you vary
07:28
your load, and that’s great to do. You
07:29
just want to make sure that things get
07:30
up to operating temperature during each
07:32
of your trips while you’re breaking in
07:34
the vehicle. And finally number 5: You
07:36
want to make sure that during those
07:37
first thousand miles or whatever it may be
07:40
you’re not towing something super heavy
07:42
something you know at its total capacity.
07:43
You may just want to avoid towing in general.
07:45
There’s several reasons for this:
07:47
First of all, it’s going to be putting a
07:49
higher load on your engine. That’s
07:50
obvious because you’ve got more weight
07:52
and to accelerate you’re going to need
07:53
more power and so you’re going to be
07:55
giving it more throttle. You want to
07:56
avoid those full throttle applications
07:58
and so in doing so you know the better
08:01
ideas to just not tow for the first
08:03
duration. Now, some vehicles are going to
08:05
be designed more for it than others.
08:06
For example, this Crosstrek says it can tow
08:08
1,500 pounds, but you may want to avoid
08:10
it entirely because this isn’t really a
08:12
vehicle setup for towing until you’ve
08:14
reached you know the end of your
08:15
break-in period so you’re not going full throttle.
08:18
Now there’s two other reasons and that
08:19
comes down to your brakes and your tires
08:21
while you may not want to talk for those
08:22
first few miles.
08:23
Both of these have break-in periods your
08:25
brakes and your tires and so you may not
08:27
have is as good of braking power and you
08:30
may not have as good of stopping power as
08:32
a result of your tires because you will
08:34
have a film essentially from the molding
08:36
process of those tires that can be left
08:39
on there so your stopping distance for
08:41
the first couple hundred miles of your
08:42
vehicle driving your vehicle isn’t going
08:45
to be as good as it will be later on and
08:48
so in an emergency situation when you’re
08:49
towing, where you know you need that
08:51
extra stopping power,
08:52
it’s good to wait until you know that
08:54
your brakes and your tires are properly broken in.
08:57
