0:00
ever filled up your tank and wondered
0:01
why it seems to vanish so quickly hey
0:03
everyone David here from automaster and
0:05
today I'm going to show you why the
0:07
average driver is literally pouring 30%
0:09
of their fuel budget down the drain this
0:11
isn't just about saving a few bucks the
0:13
same issues draining your wallet are
0:15
also shortening your engines life and
0:16
hurting performance after fixing these
0:18
exact problems for 20 years I'm sharing
0:21
everything I know the fuel efficiency
0:23
crisis let's put this in perspective the
0:25
average driver spends about $2,000
0:27
annually on fuel if you're wasting 30%
0:29
through inefficiencies that's $600 gone
0:32
every year over 10 years you've
0:34
basically bought another car with that
0:35
wasted money but this isn't just about
0:37
money these inefficiencies put extra
0:39
strain on components accelerate wear and
0:41
tear and increase emissions it's a lose
0:44
lose lose situation the good news most
0:46
fuel efficiency problems can be fixed
0:48
with proper diagnosis and maintenance
0:50
let me show you exactly what's happening
0:52
under your hood the engine efficiency
0:54
chain think of your engine as a team
0:56
where everyone needs to work perfectly
0:58
together when one player is off the game
1:00
the whole system suffers one fuel
1:02
delivery system let's start with your
1:04
fuel injectors these Precision devices
1:06
spray a fine mist of fuel into your
1:09
engine's combustion Chambers when
1:10
they're dirty or clogged that perfect
1:12
Mist becomes more like a garden hose
1:14
with your thumb over it inconsistent and
1:17
inefficient I see this in my shop every
1:19
week vehicles running on injectors that
1:21
haven't been cleaned in 60,000 Mi it's
1:23
like trying to breede through a straw
1:25
filled with dirt two ignition components
1:28
next up are your spark plugs these these
1:30
create the precise spark that ignites
1:32
your fuel when they're worn that spark
1:34
becomes weak and inconsistent look at
1:36
this difference in combustion quality
1:38
this is what's happening in your engine
1:40
hundreds of times per minute a weak
1:41
spark means wasted Fuel and reduced
1:44
power three oxygen and Air Management
1:46
your engine's computer relies on oxygen
1:48
sensors to calculate the perfect fuel
1:50
mixture when these sensors degrade and
1:52
they all do eventually your engine runs
1:55
either too rich wasting fuel or too lean
1:58
risking damage and don't forget your air
2:00
filter an engine needs approximately 14
2:02
Parts air to one part fuel for optimal
2:05
combustion restrict that air flow with a
2:07
clogged filter and your engine
2:08
compensates by using more fuel fourth
2:10
engine load factors even components that
2:13
seem unrelated to fuel efficiency can
2:15
have massive impacts dragging brakes for
2:17
example force your engine to work harder
2:19
consuming more fuel to maintain speed
2:22
underinflated tires increase rolling
2:24
resistance by up to 20% that's like
2:26
constantly driving with your parking
2:28
brake slightly engaged before I show you
2:30
the diagnostic methods I use in my shop
2:32
take a second to hit subscribe and that
2:34
notification Bell I post new content
2:36
every week to help you save money and
2:38
keep your vehicle running perfectly drop
2:40
a comment with your current MPG and I'll
2:43
try to suggest some improvements
2:44
diagnostic methods one fuel pressure
2:47
testing now let's talk diagnosis a fuel
2:49
pressure test can instantly reveal pump
2:52
or regulator issues you're looking for
2:54
steady pressure that matches your
2:55
vehicle specifications typically between
2:58
35 to 65 PSI depending on your model
3:01
when pressure fluctuates or reads
3:03
consistently low your engine compensates
3:05
by keeping injectors open longer wasting
3:07
Fuel and reducing power two injector
3:10
pulse testing a proper scan tool can
3:12
monitor injector pulse width how long
3:15
each injector stays open inconsistencies
3:18
here point to electrical problems or
3:20
clogged injectors see these uneven
3:21
patterns that's an engine crying for
3:23
help and your fuel economy is suffering
3:25
as a result three vacuum testing vacuum
3:28
testing reveals air leaks that throw off
3:30
your fuel mixture a healthy engine
3:32
maintains steady vacuum at idle these
3:34
fluctuations indicate leaks that are
3:36
forcing your engine to compensate with
3:38
more fuel than necessary four oxygen
3:40
sensor analysis modern vehicles have
3:42
multiple oxygen sensors by analyzing
3:45
their voltage readings we can spot
3:46
degradation before it seriously impacts
3:49
fuel economy a slow responding sensor
3:51
like this one can reduce fuel efficiency
3:53
by up to 15% and you'd never feel it in
3:55
normal driving five Road load testing
3:58
sometimes you need to get the vehicle
3:59
moving to diagnose resistance issues
4:02
abnormal deceleration rates often
4:04
indicate dragging brakes or bearing
4:06
problems that silently drain your fuel
4:08
tank DIY maintenance Solutions one fuel
4:10
system cleaning now for Solutions you
4:12
can Implement today quality fuel system
4:14
cleaners can remove light carbon
4:16
deposits from injectors look for
4:18
products containing pea polyetheramine
4:21
for best results for heavily clogged
4:22
systems consider a professional cleaning
4:24
every 30,000 mil the difference can be
4:26
dramatic I've seen MPG improvements of
4:29
10 to 15% after thorough cleaning two
4:31
regular filter replacement air and fuel
4:34
filters are simple Replacements that pay
4:36
dividends check your air filter by
4:38
holding it up to a light source if you
4:39
can't see light passing through it's
4:41
time for a change most Vehicles can have
4:43
a new air filter installed in under 5
4:45
minutes with basic tools this $15 part
4:48
can save hundreds in fuel costs over its
4:50
lifespan three tire pressure management
4:52
check your tire pressure monthly and
4:54
before long trips the correct pressure
4:56
is listed on the driver's door jam not
4:58
on the tire itself proper inflation not
5:00
only improves fuel economy but extends
5:03
Tire life and improves handling it's the
5:05
definition of a win-win-win scenario
5:07
four maintenance schedule compliance
5:10
your vehicle's maintenance schedule
5:11
isn't a suggestion it's science-based
5:13
preventive care following it religiously
5:16
is the single best way to maintain fuel
5:18
efficiency over time pay special
5:20
attention to these often overlooked
5:21
services that directly impact fuel
5:23
economy Transmission Service cooling
5:25
system maintenance and brake inspections
5:28
five driving habit adjustment
5:30
finally how you drive matters enormously
5:32
aggressive acceleration can use up to
5:34
60% more fuel maintaining steady speeds
5:37
and anticipating stops can improve
5:39
economy by up to 20% if you found this
5:42
information helpful please give this
5:43
video a thumbs up it really helps the
5:45
channel also check the description for
5:47
links to the diagnostic tools and
5:49
products I recommend the fuel efficiency
5:51
battle is fought on multiple fronts
5:53
mechanical condition proper maintenance
5:54
and driving habits small improvements in
5:57
each area compound into significant
5:58
savings remember wasted fuel isn't just
6:01
about money it's extra wear on your
6:03
engine and unnecessary emissions taking
6:05
control of your vehicle's efficiency is
6:07
a win for your wallet your vehicle's
