ever noticed your car feels like it's
0:01
lost its edge that zippy response when
0:04
you hit the gas pedal now feels sluggish
0:06
you might be battling an invisible enemy
0:08
under your hood that black crusty
0:10
residue is slowly robbing your engine of
0:12
its power i'm David and today I'm going
0:14
to show you exactly why carbon buildup
0:16
happens how to spot it and most
0:18
importantly how to defeat it before it
0:20
defeats your engine's performance
0:21
section one understanding carbon buildup
0:24
so what exactly is this performance
0:25
killing culprit carbon buildup is
0:27
essentially unburned fuel that
0:29
transforms into a dark sticky substance
0:31
inside critical engine components think
0:34
of your engine as a high performance
0:35
athlete just like how cholesterol can
0:37
restrict blood flow in our bodies carbon
0:39
deposits restrict the flow of air and
0:41
fuel in your engine choking its
0:43
performance over time these deposits
0:45
primarily form on three critical areas
0:47
intake valves restricting air flow
0:49
combustion chambers affecting how
0:51
efficiently fuel burns fuel injectors
0:53
disrupting the precise spray pattern
0:55
needed for optimal combustion section
0:57
two why modern engines are more
0:59
vulnerable here's what makes this issue
1:01
particularly relevant today modern
1:03
direct injection engines are actually
1:05
more susceptible to carbon buildup than
1:07
older designs in traditional port
1:09
injection systems fuel sprays across the
1:11
back of intake valves before entering
1:13
the combustion chamber essentially
1:15
washing away carbon deposits before they
1:17
can accumulate but with direct injection
1:19
technology which delivers better power
1:21
and efficiency fuel bypasses the intake
1:24
valves completely injecting directly
1:26
into the combustion chamber the result
1:28
those intake valves never get that
1:30
natural cleaning effect david I've
1:31
worked on engines with just 30,000 m
1:34
that were already suffering from
1:36
significant carbon buildup this isn't
1:37
just a high mileage problem anymore
1:39
section three warning signs your engine
1:42
is suffering how do you know if carbon
1:43
buildup is affecting your vehicle your
1:45
car will literally tell you if you know
1:47
what to listen for the most common
1:49
symptoms include noticeable power loss
1:52
especially during acceleration decreased
1:54
fuel economy tracking miles per gallon
1:56
you'll see it drop rough idle or
1:58
vibration when stopped engine hesitation
2:01
or misfires check engine light
2:03
particularly misfire codes that annoying
2:05
ping sound during acceleration if you're
2:07
experiencing two or more of these
2:08
symptoms especially in a vehicle with
2:10
over 60,000 mi there's a good chance
2:13
carbon buildup is the culprit section
2:14
four driving habits that accelerate
2:16
carbon buildup now all engines will
2:18
develop some carbon over time it's
2:20
simply unavoidable but certain driving
2:22
patterns dramatically accelerate the
2:24
problem the worst offenders are frequent
2:26
short trips under 15 minutes heavy
2:28
stopand go traffic commuting extended
2:30
idling periods consistently gentle
2:32
driving problematic your engine needs to
2:34
reach and maintain proper operating
2:36
temperature to fully combust fuel short
2:38
trips mean your engine never gets hot
2:40
enough to burn off developing carbon
2:42
deposits i've seen delivery vehicles and
2:44
short-d distance commuters develop
2:46
significant carbon issues in half the
2:48
time of highway drivers it's that
2:50
impactful the good news you can fight
2:52
back against carbon buildup with some
2:54
simple prevention strategies first and
2:56
most enjoyable give your car a good
2:58
Italian tuneup regularly what's that
3:00
simply drive your car at highway speeds
3:02
occasionally pushing it into higher RPM
3:04
ranges this helps your engine reach
3:06
optimal temperatures and can actually
3:08
burn off lighter carbon deposits before
3:10
they harden second fuel quality matters
3:12
more than you might think premium fuels
3:14
aren't just about octane they contain
3:16
superior detergent packages specifically
3:19
designed to keep your fuel system
3:20
cleaner if your vehicle doesn't require
3:22
premium consider using it every 3 to
3:25
four fill-ups as preventative
3:26
maintenance third stay religious about
3:28
your oil change intervals fresh oil
3:30
contains fewer contaminants that can
3:32
contribute to carbon formation when they
3:35
reach the combustion chamber highway
3:36
driving sessions weekly quality fuel
3:38
with detergents regular oil changes fuel
3:41
system cleaners fourth incorporate fuel
3:43
system cleaners into your maintenance
3:44
routine products specifically formulated
3:47
to address carbon deposits can be
3:48
effective when used consistently i
3:50
recommend using a quality cleaner every
3:52
3,000 mi remember these preventative
3:55
measures are significantly cheaper than
3:56
the repairs you'll face if carbon
3:58
buildup gets severe section six cleaning
4:01
solutions for existing problems if
4:03
you're already experiencing symptoms
4:05
prevention alone won't be enough you'll
4:07
need to address the existing buildup for
4:08
moderate to severe cases these are your
4:10
most effective options walnut shell
4:12
blasting is among the most effective
4:14
methods this process uses crushed walnut
4:17
shells which are hard enough to remove
4:18
carbon but soft enough not to damage
4:21
metal to physically blast away deposits
4:23
from intake valves and ports the results
4:25
can be dramatic i've seen vehicles
4:27
regain 15 to 20% of their power after a
4:30
thorough walnut blasting service
4:32
professional-grade chemical cleaners are
4:33
another approach these potent solvents
4:36
can dissolve carbon deposits throughout
4:37
the intake system when properly
4:39
administered they're particularly
4:41
effective for fuel injector cleaning for
4:42
the most severe cases physical removal
4:45
of components like the intake manifold
4:47
might be necessary to access and clean
4:48
affected areas directly while these
4:50
aren't typically DIY jobs for most home
4:53
mechanics they're absolutely worth the
4:55
investment when needed the performance
4:57
restoration can make your car feels
4:59
younger section seven special
5:01
considerations for different engines not
5:03
all engines are created equal when it
5:05
comes to carbon sensitivity direct
5:07
injection engines especially European
5:09
turbocharged models tend to be most
5:11
vulnerable many manufacturers now
5:13
recognize this issue and have begun
5:15
implementing dual injection systems that
5:18
combine direct import injection to help
5:20
prevent carbon buildup if you're
5:22
shopping for a new vehicle and this is a
5:24
concern ask specifically about how the
5:26
manufacturer addresses carbon buildup in
5:29
their engine design conclusion: Carbon
5:31
buildup might be invisible to the casual
5:33
eye but its effects on your driving
5:35
experience and engine longevity are very
5:37
real remember prevention through proper
5:39
driving habits and maintenance is your
5:41
first line of defense quality fuel and
5:43
occasional system cleaners can
5:44
dramatically slow buildup professional
5:46
cleaning services can restore loss
5:48
performance when needed give your engine
5:50
what it needs clean components proper
5:52
maintenance and the occasional spirited
5:54
drive and it will reward you with years
5:56
of responsive reliable performance this
5:58
is David reminding you that
6:00
understanding what's happening under
6:01
your hood is the first step to becoming
