we're gonna be talking about five things

which you should never do in a brand-new

vehicle now the definition of brand-new

of course will change depending on the

vehicle but generally we're going to be

talking about the first thousand miles

of which you're going to be breaking in

your vehicle so check your owners manual

it'll tell you you know what that

break-in period is but we're gonna be

talking about five things which you

shouldn't be doing during that time

now I think it goes without saying but I'm

going to say it anyways

in the event of an emergency ignore

everything in this video and just do

whatever you need to do to be safe

like I said I think it goes without

saying but some people out there may

value their car over their own life you

shouldn't do that you should value your

own life so you know the biggest things

were going to get into of course have to

relate to the engine and these are going

to get somewhat controversial but you

know one of the biggest things about

breaking in a new vehicles breaking in

the engine and making sure that these

piston rings seat properly on your

cylinder wall so on your cylinder wall

you know you've got that freshly home

cylinder bore and you want to make sure

you get a nice seal between that and

these piston rings now these piston

rings have some spring tension in them

which allow them to expand out and rub

against that cylinder wall but that's

not really what's going to be doing the

majority of wearing in this piston ring

on that cylinder wall really you've got

the combustion process occurring on top

of it

those gases are going to pass in here

they're going to get in these gaps get

behind the piston ring and force that

piston ring out and expand it out on

that cylinder wall and that pressure is

what's going to wear down that cylinder

bore now you don't need an excessive

amount of pressure to do this and this

is where it gets kind of controversial

so points1 into don't floor it and

point2 don't bring it all the way up to

you know red line to your highest RPM

and you know there's certainly people

out there will say heartbreaking is

necessary

we're going to talk about you know kind

of why that's not true based on all the

data that's out there based on all the

information that's out there and based

on what all the manufacturers out there

recommend and so basically what you're

doing like I said your ceiling these

piston rings up against that cylinder

bore and wearing it down to have a nice

seal now you don't want to do this too

fast and with too much pressure

there's no reason you can cause damage

if there are imperfections you're going

to wear down those infamous

imperfections too quickly and that could

cause hot spots which could cause

problems

so you want a nice gradual aware of that

cylinder bore with

these piston rings so that you create

that good seal and some people out there

will say you know for performance if you

want maximum power you need to florina

get that perfect seal on the only way to

do that is with super-high pressure but

if you look at performance cars and what

they recommend this is not what they

recommend doing so just a few examples

starting with the Nissan GTR for the

first 300 miles they recommend not going

over fifty percent throttle and they

recommend not going over 3,500 rpm and

that's for those first three hundred

miles and so you know as you can see i

mean obviously the GTRs performance

vehicle obviously they wanted to have

the performance that you expect from it

why would they recommend that I if they

didn't you know believe that to be true

if you know the best method of breaking

in that engine was with lighter throttle

applications and without going to super

high rpm another interesting example is

the new acura nsx and one of the cool

things that they do is they break this

in from the factory and so they have a

procedure where they put the equivalent

of about a hundred fifty miles on the

engine varying the load and not

exceeding 4000rpm on the engine and what

they say this does is that when the

customer takes delivery of their new NSX

they can go straight to the track

because they've already put in this

engine break-in process and so you know

from the factory the cars good to go you

can take it out to the track now why

would a cura spend the time and spend

the money on breaking in an engine

keeping it under 4,000 rpm varying the

load if it wasn't necessary to do for

the safety and performance of that

engine they wouldn't it would be a waste

of time and money like i said and so you

know these are just another example out

there of a company which doesn't break

in from the factory that's their

procedure keep it under 4,000 rpm

through the equivalent about a hundred

and fifty miles and then let the

customer thrashing on the track on day

one so cool thing that they do actually

don't have to do the break-in procedure

another example is the Corvette the new

Corvette the c7 you know they recommend

and they specifically say for

performance reasons and you don't want

to exceed 4000rpm and you don't want to

do full throttle starts in the new

Corvette basically in those first 500

miles and then they have a separate

procedure for the next thousand and they

have you know a total of fifteen hundred

miles of breaking but for those first

500 keep it below 4000 RPM and don't

floor it from a start so you know more

recommendation

he's out there these are different

companies they're all saying very

similar things and actually had the

honor to speak with someone who worked

in FCS performance engine division they

actually have their own land speed

record car where they took a two liter

out of a dodge neon srt-4 and you know

boosted that up to i believe 800

horsepower of an absurd amount of boost

in it and you know they had they were

telling me they're breaking procedure

for that engine with 800 horsepower and

once again it was varying the load and

it was changing the RPM but not going to

high believe the highest he went was

4,000 rpm and asked him you know you

work in this world you have access to

this data you know is there any

advantage of a heartbreak and he said

absolutely not there's no advantage to

it you know it's just a risk and so it's

an unnecessary risk

you can do a lighter break-in obviously

don't baby the vehicle give it you know

decent throttle give it half throttle

something like that but you don't want

to floor it out because you can run into

that risk of causing damage if you get

things in there too hot where these

imperfections lie you want to wear them

down more gradually rather than quickly

now yes manufacturing tolerances have

greatly improved and it's always getting

better but this doesn't necessarily

eliminate the need for break-in period

typically what it just means is that the

break-in period will be shorter than

they previously were as a result of

better manufacturing tolerances

ok so we have points 1 and 2 don't floor

it don't bring it up to redline and our

third we're going to talk about don't

use cruise control and really the reason

why you don't want to use cruise control

is because you want to vary that engine

rpm as you're driving and when you set

cruise control

you're just gonna have one set engine

rpm especially with manual transmission

vehicles which obviously aren't going to

shift for you but basically don't want

to use cruise control because you don't

want to keep it at a constant speed you

want to vary the engines load and you

want to vary the engine speed so that it

gets used to all these varying

conditions and it properly wears it in

so you know you can take that into

consideration and think you know maybe

you shouldn't do a thousand mile road

trip as the first trip in your car

because you're probably just gonna be

sitting on the highway at one set speed

at once at throttle position at one set

RPM and so you really want to bury the

conditions for a proper break in moving

on

to number four you want to make sure

that you avoid short distance travelled

by short distance trouble what I mean is

trouble that doesn't let your engine

fully warm-up you want to make sure that

everything gets up to operating

temperature during all of your trips

especially for those first thousand

miles because you want to make sure that

you break everything in at operating

temperature you want to make sure you

have proper oil flow which is only going

to happen once you get things up to

operating temperature you also want to

make sure that things are expanded to

their final state so that when they're

breaking in for example that cylinder

it's going to expand out and we're down

that cylinder wall and so you want to

make sure it's at its operating

temperature so that everything's in that

expanded state in its warm estate so you

get that proper break in

now that doesn't mean short distance

travel as far as like driving around the

city isn't going to be good it's great

to do that you know driving around the

city you very your engine rpm you very

your load and that's great to do you

just want to make sure that things get

up to operating temperature during each

of your trips while you're breaking in

the vehicle and finally number five you

want to make sure that during those

first thousand miles or whatever it may

be

you're not towing something super heavy

something you know at its total capacity

you may just want to avoid towing in

general there's several reasons for this

first of all it's going to be putting a

higher load on your engine that's

obvious because you've got more weight

and to accelerate you're going to need

more power and so you're going to be
