Doing This Will Save You Thousands in Engine Repairs

rev up your engines, modern car engines
are complicated they cost a small
fortune if they wear out and have to
replace them and rebuild them, so you
want to make it last as long as possible,
so I’m gonna give you some tips many of
which you probably never even thought
about the make to last as long as it
possibly can, now of course the number one
to change your oil and filter regularly
I’m not gonna beat that, that’s an old
horse that’s been beaten to death, just
please do it, if you don’t do any
maintenance on your car at all except
change the oil at least you’re doing
something, use the oil that it suggests
on the car don’t use a different oil,
modern engines are very particular about
their oil, and use a quality brand of oil
there are many quality oils out there
like right here they all have the API
service rating, that said changing oil
is a boring subject, here are some
things you may never have thought of to
make your engine last as long as
the tire pressure in your car, you might
think what does tire pressure have to do
with my engine lasting longer, well if you
have consistently low tire pressure
tires will sit flatter, they’ll get
hotter because there’ll be more friction
from not having the correct amount of
air in them, the more friction there is
the harder the engine has to work to
spin around, just like dirty oil in your
engine which is more friction which is
gonna wear the engine out faster, if your
tires don’t have enough air in it you’re
gonna have extra friction going down the
road, it’s gonna strain the engine more
and it will wear it out faster, now the
next way to make your engine last as
long as it can might sound crazy too, keep
your air filter clean, check it every
once in a while, you can knock the dust
off even vacuum it off and when it gets
dirty and you put it off to the Sun and
you can’t see the light anymore replace
your air filter, and here’s the main
reason, sure you’ll get better gas
mileage with a clean air filter, but if
your air filter is clogged, then your car
isn’t going to have the right air fuel
ratio, because there’s not enough air
sucked into the engine, and if the air
fuel ratio isn’t right, the engine can
run too hot or can run too cool
and both are actually bad for an engine,
if your engine is running too lean
then the Pistons get hotter
of course they’re gonna burn out faster
if your engine runs too rich,
of course you’re wasting gas, but a rich
engine often is dumping too much gas
that gets by the piston rings and gets
in the oil, and contaminated oil in your
engine with gasoline will wash the
lubricants off of all the bearings and
metal parts, and your engine will wear
out faster,
and speaking of wearing out faster, you
want to keep your cars cool and clean,
years ago you more or less had to or
the vehicle would just rust and fall to
pieces, as a young mechanic engines were
made out of cast iron those things all
rusts, the coolant as anti rust
inhibitors in it to keep that from
happening, now over time the inhibitors
break down and things start to rust, when
I was young mechanic you had to change
your coolant like once every three years
the stuff didn’t last all that long, but
you might say hey Scotty this is modern
times most of the engines are made out
of aluminum and
aluminum doesn’t rust, aluminum corrodes
just as bad as cast iron or steel rust,
and the modern coolants of course have
anti-corrosion additives to keep the
aluminum from corroding, but they wear
out over time just like anything else
does, so you want to check on your own
model car about when to change the
coolant to keep the engine from wearing
out, some modern cars like Toyotas,
some of them come with a seven-year
150,000 mile Hoat coolant that stands
for hybrid organic acid technology and
if you have one like that and you only
have to change the cooler once every
seven years or once every 150,000 miles,
hey it’s not that big of a deal but you
want to do it when it reaches that level,
because aluminum has many advantages
over steel and cast iron for use in
engines, but one big disadvantage is the
stuff is much softer, and so once you get
impurities in the system it will corrode
and it will come apart much faster than
steel or cast iron because it’s a much
softer metal, now the next way to make
your engine last twice as long is don’t
over rev the engine, don’t always
be driving so that the engine is
spinning as fast as it can and either
manually shifting the gears late or
every time you take off
floor is so it goes as fast as I can before
shifts into second gear, the more you rev
the engine the faster it’s gonna wear out
I’m not saying you can’t have fun
driving your car around, most modern cars
you’re going the speed limit someplace out
here in West Texas the speed limit is 85
miles an hour,
that isn’t gonna hurt any modern car but
you don’t want to go zero to 85 miles an
hour as fast as you possibly can, you
just want to do it gradually just like
when you’re driving around here, I live
in a big city of Houston, it makes no
sense to be revving and going as fast
you can in a city because there’s traffic
jams everywhere, you don’t want to wear out
the engine and the transmission by
revving it up too much and that leads
me into the next way to make your engine
last twice as long, you want to make sure
the transmission is full of the right
fluid and clean fluid, as it wears it
gets dirty there’s more friction, it
works less efficiently and of course
your gas mileage will go down, but that makes
the engine work harder, anything that
creates more friction between the engine
and the wheel spinning on the road is
gonna make the engine wear out faster,
and I know some of these modern cars say
oh the automatic transmission fluid is
lifetime, yeah ask the engineers what
that means I have, what the engineer who
told me was, well Scotty that means that
the fluid is good for the lifetime of
the transmission, and I’d say what’s the
lifetime of the transmission, and they’d say
like oh well the warranty is for 75,000
miles, so it still is a good idea to
change that fluid regularly, don’t listen
to people that say oh it’s a lifetime
because when the lifetime is up they’re
not going to give you a new transmission
free, you’re either gonna pay them thousands
thousand dollars to fix it or replace
the transmission, or they’re gonna sell
you another car and say, oh well that
one’s worn out it’s lifetime is over, time
for a new car, and modern cars are so
computer-controlled and so interrelated
that even for a mechanic like myself
who’s been doing it for 51 years, I can
get cars come in and it’s very hard for
me to figure out, does it have an engine
problem or does it have a transmission
problem, because they both have sensors
that feedback to a computer and it can
really confuse you as to where the root
problem is, so you don’t want to get in
that situation in the first place, if you
take care of the fluid in the
that’ll also take care of the engine, the
next tip is a very important tip and
it’s probably one that most people don’t
think of, you want to minimize the
starting and stopping of your engine and
here’s why, when you start up an engine
that’s when the most wear occurs inside
an engine, because the oil has to be
pumped up to the top to lubricate the
cams, it wears the most every time you
start it up, so if you’re continually
half a mile to the convenience store and
back, turn it on, turn it off, that will
actually wear your as you’re out faster
than taking a long trip all the time,
as a general rule of thumb highway
driving at a steady speed like 65 miles
an hour, wear in the engine is about 10%
of what it is in stop and go and start
and stop city driving, let’s say you
drive 2,000 miles on a highway at 65,
that’s equivalent to like 200 miles of
stop and go and start and stop, because
there isn’t that much wear when you’re
going down the road and everything’s
functioning smooth and the wind’s
blowing cool in the engine, that’s the
least where you’re ever gonna get on
your engine, and that’s one of the main
reasons that you can see guys in these
big 18 wheel diesel trucks driving on
the highway and they say, oh wow you know
they got a million miles on this truck,
only a few hundred thousand of those
miles had been all stop and go traffic
in a city, that thing would be in a junkyard
now, it’s because it’s mainly going 65
miles on the highway where everything’s
running smoother, you will minimize wear
by minimizing the amount of times you
start and stop the vehicle, and this is a
big reason I’m not a fan of that modern
start/stop technology when you come to a
stop the engine turns itself off, because
yes over time that will wear your engine
out faster there’s no doubting, and my
last tip when you do need parts use
quality parts don’t use the cheapest
thing you can get your hand on, one real
big example is a mass airflow sensor
these sensors measure how much air goes
in the engine so the computer decides
how much fuel to spray with the fuel
injectors to make it run right, and if
you have one that’s gone bad and you say,
oh the dealer one costs 350 bucks but I
can get this one that’s made in
China for $89, believe me don’t try the
$89 one, because air fuel ratio has to be
perfect for a modern car and those
sensors are very complex inside, they’re
relatively expensive to create and if
you get a cheap knockoff one in the past
I tried to save customers money by doing
that and always bit me in the rear end,
sometimes they didn’t work at all
sometimes they worked worse, sometimes
they worked for a few months but then
when I started seriously analyzing them
every time I put one on, I get my fancy
scan tool out, and believe me hardly any
of them work perfectly they all had
glitches in them, so if your car does
need parts, make sure you’re getting
quality ones especially if you’re
talking about any kind of computer
sensors, you want to stick to quality
electronic parts when your car needs
them, so now you know how to make your
engine last at least twice as long, so if
you never want to miss another one of my
new car repair videos, remember to ring
that Bell!

  1. the start stop engine i HOPE we all knew to begin with .. the amount of gas alone that it takes to start an engine .. you can idle for 2 mins with :-s .. so do NOT use that damn blue motion ..

  2. What year do you consider the "modern car" begins. I have a 97 Camry 2.2. Code said I need a vapor pressure sensor. $190.. at the dealer, $30 from China, or $30-45 used and tested on eBay. Suggestions? Obviously China is out of the question.

  3. I LOVE your videos. They are honest, and to the point and of course full of your wisdom which we do not get too often. Thank you for something worthy of watching.

  4. You always say modern cars. What year and after is considered a modern car? Is this like 2010 and after????

  5. Great advice, Scotty! I love your "LIVE FREE OR DIE" motto. I'm a Vietnam Veteran – Navy – Brown water sailor – river patrol – dealing with diesels. My cousin lives in Kingwood, but, alas, I'm in Commiefornia.

  6. Fifty-one years as mechanic? Were you 8 when you started? LOL, how young are you? I love your videos. When ever I need an answer, you are the man, and you have a simple solution, even a girl can figure it out. Keep those videos comin, young man!

  7. You talk too much there are cars not to be wear because of you but all cars did not last long.hows that.

  8. so I've been doing good then cuz every time every day I go to the ampm mini market and get me a soda and get out of the car I leave my big old Mercury 4. 6 L V8 running I don't even shut it off I do that a lot of places I never shut it off man ever start and stop that big motor I don't want to replace my damn starter I'm too lazy that's a joke

  9. Scotty; thanks for the great videos!
    I have a question about my 2016 Toyota Tacoma TRD Off Road. I was driving around 60 and went to pass someone. As the engine revved up, I heard some banging around in the engine compartment. I pulled over and found that my cooling fan more less exploded, all blades broke off. They also hit the fan shroud and damaged that as well.
    Not sure why this happened? Seems like the RPM's initiated this…can you please give me some ideas on this? Thanks!

  10. How come your garage is so packed full? Wouldn't it be nice to actually use the space to work on making your toyota last forever?

  11. When is it better to shut off your engine versus leave it running? I routinely shut it off when when parked and the anticipated wait is more than 2-3 minutes. For example, my wife is picking up a few things from the store, I’m waiting on a prescription in the drive through etc. I’ve see young people sit in their car for 20-30 minutes with the engine running while they eat their lunch or surf the internet. IMO that wastes gas, pollutes the air and puts unnecessary wear on an engine. Seems there’s a limit to “just leave it running”. Thanks for any guidance

  12. That's why you get an old carbureted 350 chevy and remove the computer. Bam, easy to fix and unbreakable.

  13. The reason semi get so many miles and still run is the fuel manly, diesel lubes the eng. Better then gas. Plus doing P.M on a regular basis.

  14. Your video is right on topic and so true. But one thing that gets me is when people put regular tap water in their cooling system. I understand that if they are going to flush it out soon with destilled water. But you know they don't, which the impurities would deteriate or damage the engine.

  15. Might you see this and answer this question: what year if you would purchase a Porsche 911, and what manufacturer of minivan? Thank you sir.

  16. Beware of shady dealership mechanics. I changed a cabin air filter this week on my wife's Nissan Cube. The blower was making strange noises and turned out to be loaded with stuff that got past the filter. The filter had actually blown out because of clogging. Here's the rub: The dealership had been paid at least once to change this filter. The factory tie wraps were still in place on the glove box! These are always cut off and discarded when the filter is changed. This is not an engine issue, but be careful who you trust with your mechanical work.

  17. I hated cares, but when I start to listen to you I changed my mind because you make 't sound so sexy as an hot carlifonia girl with long legs on high hils.

  18. Hey Scotty, i drive alot and go 10 to 20 miles then stop and then do it all over again. I know you said it's not good to keep starting and stopping your Engine. So would it be better to leave my Engine running? Thanks for the knowledge and your vids.

  19. Scotty Kilmer🥇……..The Best!!!! …..Thank you Scotty…….learning so much from you….

  20. False on air filter- computer controls air/fuel mix. Will NOT cause worse mileage, may cause loss of power.

  21. Really appreciate your comments and advice. We're about the same age and the newer cars confuse me. Thank You!

  22. Thank you. If its possible, would you please tell the relation of speed and RPM meter. For 55 MPH/3000 RPM,
    Is this right? Thanks.

  23. Exactly what I told my buddy about not buying that RAM in the first place, let alone the stop and start engine option, or maybe it's standard.

    A rental car company gave me an upgrade and I ended up with a RAM 1500 like his. At one stop sign the damn thing stopped and started twice. That engine must have stopped and started 8 times more than I ever told it to in 10 days, imagine in 5 years.
    He argued with me they designed the engine so it wouldnt cause any wear, it's his favorite feature. I told him to a corporate mind that means not enough wear to break it during the warranty for whatever percentage of vehicles they decided was still profitable if they had claims.

  24. Haven’t changed the oil on mine for at least 5 years now never had a problem just dont over-rev the engine.

  25. Scotty ..i like yur clutter yur looking for a lawn yur pile of goodies in therr…is therr a weed wacker. In therr…👏💕…i never thought of it..thanks ..a 💰💴💸💳

  26. Hi Scotty. I'm learning many things from your vídeos. I like'em all. And, with all the respect, you remind me Joe Pesci, one of my favorite 80's and 90's movie actors. Hope you don't bother. Greetings from México 🙂

  27. I am addicted to these videos , I consider that if I don’t watch at least one of Scotty’s videos each day I will never increase my knowledge base to that of GURU , being an Australian makes no difference , I feel Scotty is the ultimate GURU on how to make your car last AS LONG AS POSSIBLE , I thought I was doing a good job with my 20 year old falcon , well it turns out I can be doing a shitload BETTER , thanks Mr Kilmer.

  28. You are so awesome…I have a 2012 Honda crv I wana keep forever so this is why I subscribed to you…I really dig u…thank u

  29. I thought if your transmission fluid was never changed before purchasing that it would be bad to change now due to the grip material actually being in the fluid, for reference got a 96 Camry with 260k miles

  30. I have a 2002 pathfinder. When the rpms hit 2500 it wants rev up and down. In park put foot on 2500 and it goes up and down. Put a new iac. Throttle body sensor. Had computer redone had burnt smell. With only 100 miles on it that problem is doing it again. I need wheelchair and its heavy I need this pathfinder to be fixed. Please help…ty

  31. Scotty, to an extent, I understand what you're saying about not going aftermarket on a replacement MAF sensor, but I'm looking at a Denso ($65) or a Delphi ($75) for my son's '07 Mazda 6 2.3L with 180k miles (wire/bulb surface is rough on the leading edge). If it was your car, would you buy for $300+ from Mazda, or would you buy the Denso, the likely (OEM) supplier to Mazda?

  32. Hey Scotty! Quick question for you. I have an 05 Chevy Express 1500. I have a temperature gauge that's on cold. I changed the temp sensor and the thermostat nothing. Gauge is still on cold. There's are a couple of codes on there: p0101, p0128, P0171 and p0174. Help please
