🚗 Debunking Winter Car Warm-up Myths

The video addresses the common debate about whether or not to warm up your car in the winter. The host discusses a news article that humorously advises against warming up cars, which is traditionally a popular practice. The article is said to recommend against it, claiming it can damage the engine. Various sources such as Firestone Complete Auto Care, Smart Motors Toyota, the U.S. Department of Energy, NAPA Auto Parts, and Chuck's Auto Repair are mentioned as authorities supporting the claim that modern vehicles built after 1980 do not require warm-up before driving. The video also humorously points out that while some suggest not warming up the car to protect the engine, others might do so to protect the interior from cold.

05:03

🔍 Analyzing the Effects of Cold Weather on Engines

This paragraph delves into the mechanics of why some believe warming up a car can harm the engine. It mentions that letting a car idle in cold temperatures can supposedly strip away oil from the engine's pistons and cylinders, which are crucial for the engine's operation. The video explains that gas-powered cars need oil to stay lubricated, and that the oil pump should circulate oil within a minute of starting the car. However, the host challenges the idea that idling to warm up the cabin would strip away oil, arguing that the oil pump continuously supplies pressurized oil regardless of whether the car is idling or driving.

10:04

🔋 Electric Vehicles vs Gasoline Engines in Cold Weather

The video contrasts the advice for electric vehicles (EVs) with that for gasoline-powered vehicles. For EVs, it's suggested to warm up the car before driving to preserve battery range, as the cold can affect battery performance. The video humorously points out the disparity in advice: while EV owners are told to warm up their cars to protect the battery, gasoline vehicle owners are warned against it to protect the engine. The host then discusses the manufacturer's recommendations for warming up gasoline vehicles, specifically mentioning Subaru's advice to warm up the vehicle before driving.

15:04

⏰ Manufacturer's Recommendations on Winter Car Warm-up

The paragraph focuses on what Subaru, as a manufacturer, recommends regarding winter car warm-up. It mentions that Subaru advises warming up the vehicle before driving, as indicated by a blue temperature light that signals when the engine is cold. The video explains that during this period, the engine idles higher to warm up quickly and safely. The host also discusses the importance of warming up not just for comfort but for the mechanical well-being of the vehicle, such as ensuring that engine oil, transmission fluid, and coolant reach appropriate temperatures for effective operation.

20:06

🤔 Logical Considerations for Winter Car Warm-up

In the final paragraph, the host shares a personal perspective on the logic behind warming up a car in winter. They argue that warming up the engine gradually is better for the engine than driving it immediately after starting, as this could create hot spots and stress the engine components. The video concludes with a call for viewer opinions on the matter, asking whether they warm up their cars and why, reflecting a community engagement approach to the topic.

Mindmap

Keywords

💡Warm-up

Warm-up refers to the practice of allowing a vehicle's engine to idle for a short period before driving, especially in cold weather, to allow the engine to reach its operating temperature. In the video, the debate over whether or not to warm up a car is central, with the host exploring various expert opinions and manufacturer recommendations. The script mentions that modern vehicles, particularly those built after 1980, do not require traditional warm-up methods due to advancements in engine technology.

💡Idling

Idling is the act of letting an engine run without applying its power, such as when a vehicle is stationary. The video discusses the potential harm of excessive idling, particularly in cold weather, as it may lead to engine damage by stripping away oil from critical engine components. The script suggests that modern engines do not benefit from prolonged idling during warm-up.

💡Engine

An engine is a machine designed to convert one form of energy into mechanical energy. In the context of the video, the engine is the heart of the vehicle, and its proper functioning is crucial. The script delves into how modern engines with fuel injection systems handle cold starts differently than older carbureted engines, affecting the necessity of warming up.

💡Lubrication

Lubrication is the process of reducing friction between moving parts by using oil or another substance. The video script mentions that letting a car idle in cold temperatures can strip away oil from the engine's pistons and cylinders, which are critical components that require lubrication to function properly and prolong their life.

💡Oil Pump

The oil pump is a mechanical device in an engine that circulates oil to lubricate and cool the engine's moving parts. The script discusses the misconception that the oil pump does not supply oil during idling, which is incorrect as it continuously supplies oil when the engine is running, regardless of whether the vehicle is idling or driving.

💡Fuel Injection

Fuel injection is a system that supplies fuel to an engine in a precise metered quantity, as opposed to carburetors. The video highlights that modern fuel-injected engines are more efficient at managing fuel mixtures in cold temperatures compared to older carbureted engines, making the traditional warm-up less necessary.

💡Carburetor

A carburetor is a device that mixes air and fuel for internal combustion engines. The script contrasts carburetors with modern fuel injection systems, noting that older vehicles with carburetors required a warm-up period to adjust the air-fuel mixture properly in cold weather, which is not the case with modern engines.

💡Emission

Emission refers to the release of pollutants into the environment. The video touches on the environmental aspect of idling, suggesting that it contributes to air pollution. However, the script also points out that both idling and driving in cold conditions result in emissions until the engine reaches closed-loop operation.

💡Electric Vehicle (EV)

An electric vehicle, or EV, is a vehicle powered by an electric motor instead of an internal combustion engine. The script differentiates the warm-up practices for EVs from those of traditional gasoline-powered vehicles, noting that EVs may require pre-warming to preserve battery range and ensure comfortable cabin temperatures.

💡Block Heater

A block heater is a device used to warm up an engine, particularly in cold climates, by heating the engine block directly. The video script suggests that in extreme cold temperatures, using a block heater is beneficial for both the engine and the vehicle's fluids, ensuring they are warmed up before driving for optimal performance and protection.

💡Closed-loop

Closed-loop refers to a system, such as a vehicle's engine management system, that has feedback mechanisms to regulate its operation. In the context of the video, once the engine reaches a sufficient temperature, it enters closed-loop operation, where sensors adjust the air-fuel mixture for optimal performance and efficiency. The script implies that both idling and driving contribute to reaching this state.

play00:00

greetings viewers welcome back to the

play00:01

channel in today's video the age-old

play00:04

debate that happens every single year

play00:06

this time of year to warm up or not to

play00:10

warm up your car before driving in the

play00:12

cold today we're going to look at a news

play00:14

article that I ran across the other day

play00:16

on Facebook that made me laugh out loud

play00:18

we're going to look at the

play00:20

manufacturer's recommendations and we're

play00:22

going to look at this logically and

play00:25

sensibly and try to put the bed once and

play00:27

for all to or not to warm up your car

play00:31

before driving in the winter

play00:33

[Music]

play00:41

thank you

play00:43

so guys it is cold and I mean it is cold

play00:45

I'm literally straddling a kerosene

play00:48

heater right now trying not to freeze

play00:50

but we're going to start off the video

play00:51

by looking at this article I saw the

play00:54

other day on Facebook saying to not warm

play00:57

up your car before driving in the winter

play00:58

time now this was posted on ABC 10.

play01:02

we're going to look at it yes warming up

play01:04

your car before driving in cold weather

play01:06

can damage the engine

play01:09

yeah that's what they're claiming here

play01:12

excessive idling does not do anything

play01:14

positive for your engines long-term

play01:16

Health we're going to look at this I'm

play01:18

going to put it on screen I'm going to

play01:19

read through it real quick and then

play01:21

we're going to talk about some of the

play01:22

claims they're making here on why not to

play01:25

warm up your car and why it's destroying

play01:27

your engine so we're going to paraphrase

play01:29

and jump around a little bit I'm not

play01:31

going to read this word for word I will

play01:33

leave a link to this article in the

play01:35

description of the video if you want to

play01:36

check it out yourself so frigid

play01:38

temperatures are here it's a common

play01:39

practice for many drivers to warm up

play01:40

their car before driving most have a

play01:43

remote start feature uh but briefly

play01:45

viewers want to know if they're doing

play01:47

potential harm to their engine so they

play01:51

went to some sources and they listed the

play01:53

sources here uh Firestone Complete Auto

play01:55

Care

play01:57

Smart Motors Toyota in Madison Wisconsin

play02:00

uh the U.S department of energy

play02:03

NAPA Auto Parts and Chuck's Auto Repair

play02:06

in Seattle Washington

play02:08

so answer true yes warming up your car

play02:12

before driving in the cold weather could

play02:14

cause long-term damage to the engine

play02:17

ridiculous

play02:19

most Vehicles built after 1980 no longer

play02:22

need to warm up before driving and

play02:24

experts say driving after 30 seconds to

play02:27

a minute after starting your car is the

play02:29

best practice

play02:30

let's find out why they think that uh

play02:33

you're going to destroy your engine by

play02:35

letting it warm up

play02:37

it's true that warming up gas powered

play02:40

vehicles before driving in cold weather

play02:41

can cause damage to the engine according

play02:44

to Firestone Complete Auto Care and

play02:46

Smart Motors Toyota

play02:48

quote if you're one of many drivers who

play02:51

thinks it's important to turn on your

play02:53

car let it sit for a bit before hitting

play02:56

the road in wintry weather you could be

play02:58

doing your engine more harm than good in

play03:01

quote Firestone says

play03:03

letting your car idle in cold

play03:05

temperatures can shorten the life of

play03:07

your engine by stripping away oil from

play03:10

the engine's pistons and cylinders two

play03:13

critical components that help your

play03:15

engine run

play03:17

gas powered cars need oil to keep their

play03:20

engines lubricated

play03:21

when you start the car an oil pump

play03:23

circulates the oil in less than a minute

play03:26

but if you let your car idle to warm up

play03:29

the cabin the oil can get stripped away

play03:32

because apparently the oil pump doesn't

play03:35

constantly Supply pressurized oil to the

play03:38

engine whether it's idling or driving

play03:40

down the road or what RPM is at

play03:44

keep that in mind

play03:45

Chuck's Auto Repair explains quote

play03:48

constantly letting a cold engine idle

play03:51

can actually be counterproductive

play03:53

because it gradually strips away oil

play03:55

from the engine's pistons and cylinders

play03:57

dot dot dot here's the problem when the

play04:01

engine is cold the gas may not evaporate

play04:04

completely as it combines with the air

play04:08

for more recent cars with electronic

play04:10

fuel injection there are sensors that

play04:13

detect

play04:14

this and compensate by adding more gas

play04:17

to the mixture when there is excessive

play04:19

fuel in the chamber some of it

play04:21

condensates into onto the cylinder walls

play04:25

and strips away the lubricating oil when

play04:28

the lubricating oil is gone components

play04:31

like the cylinder liners piston rings

play04:33

will wear prematurely quote

play04:36

quote again less oil means more friction

play04:38

more wear and tear and a shorter life to

play04:41

your engine in quote Firestone says

play04:45

while some people let their cars idle to

play04:47

warm up the Interiors other may actually

play04:48

be trying to protect the engine because

play04:50

of outdated guidance outdated guys

play04:53

remember that

play04:55

Firestone is Smart Motors Toyota both

play04:58

say that most cars made before 1980 did

play05:02

need two quote unquote warm up when it

play05:05

was cold out this is because the old

play05:07

cars had carburetors that regulated fuel

play05:10

air mixture within the engine and could

play05:12

not be adjusted for the air fuel ratio

play05:14

in the cold blah blah blah

play05:17

in cold temperatures carburetors blah

play05:19

blah blah blah who cares

play05:22

again 1980s carburetors blah blah blah

play05:25

blah so instead of waiting for your car

play05:27

to warm up in the winter most

play05:29

manufacturers recommend driving off

play05:31

gently after 30 seconds because the

play05:32

engine warms up faster when the car is

play05:34

being driven according to the U.S

play05:36

department of energy quote this means

play05:38

that your cold day driving routine

play05:41

should look something like this bundle

play05:43

up start the car scrape the ice off of

play05:45

the window and mirrors and get in the

play05:47

car and get going exclamation point in

play05:50

quote Firestone says

play05:52

just make sure you don't accelerate too

play05:55

fast or rev your engine too much in the

play05:58

first few moments you start driving in

play06:00

the cold

play06:01

quote this can add unwanted strain to

play06:04

your bearings and flood the combustion

play06:06

chamber with gas which in turn will take

play06:09

miles off of your engine's life end

play06:12

quote from Smart Motors Toyota now on

play06:15

the flip side rules for thee but not for

play06:18

me for owners of electric vehicles you

play06:21

got to put EVS in here which don't have

play06:24

a traditional engine the above

play06:26

information doesn't apply according to

play06:28

blog post on NAPA Auto Parts website

play06:31

instead Napa advises EV owners to warm

play06:35

up their car before they're unplugging

play06:37

because it can help preserve your

play06:39

battery range don't forget you got to

play06:42

use all of your battery power to warm up

play06:44

that cabin also your lithium batteries

play06:46

suck at charging and discharging

play06:48

properly in the cold among other issues

play06:52

that the code plays on your electric car

play06:54

quote EVS have to draw on electricity to

play06:58

warm the interior if you enter a car

play07:00

with a cold cabin and begin driving the

play07:02

vehicle need to take from its stored

play07:05

electricity to bring the inside air

play07:07

temperature to a pleasant temperature

play07:09

this will tax the ev's battery and leave

play07:13

you with less driving range in quote

play07:16

Napa says

play07:17

so there you go guys us fuel injected

play07:21

gas powered vehicles we can't warm our

play07:24

cars up in the winter time we got 30

play07:27

seconds and then we need to start

play07:28

driving because we're going to destroy

play07:30

our engine because

play07:31

apparently the oil pump doesn't pump oil

play07:33

continuously and when you idle your

play07:36

engine doesn't get any oil and there's

play07:38

so much of a rich fuel mixture that it's

play07:41

just stripping all the oil completely

play07:43

out of your engine and it's going to

play07:45

seize up like a rock but if you have an

play07:46

electric car don't worry let it warm up

play07:48

plug it into the wall use that

play07:50

electricity get yourself all nice and

play07:52

toasty before you take off down the road

play07:54

so let's unpack what we've read here

play07:56

we're going to go over the article again

play07:58

we're going to talk about Subaru what

play08:00

they say in the owner's manual talk

play08:02

about Subaru system and just think

play08:04

logically about how the mechanics of an

play08:07

internal combustion engine work and

play08:09

dealing with cold weather so guys let's

play08:12

unpack what we just read in that article

play08:14

and uh man they're really trying to

play08:16

scare some people that don't know much

play08:18

about their vehicle so the first point

play08:21

idling your engine cold or letting it

play08:23

warm up uh the fuel is going to

play08:27

completely strip the oil out of your

play08:30

cylinder and it's going to cause high

play08:32

friction and wear your pistons and your

play08:34

cylinders more so they talk about the

play08:37

oil pump providing oil to the engine

play08:39

within 60 seconds of starting the engine

play08:42

but then they make it seem like the oil

play08:45

pump just doesn't work unless you're

play08:46

driving

play08:47

absolutely false the oil pump is

play08:49

constantly supplying uh between 40 and

play08:53

60 PSI of oil pressure

play08:55

anytime the engine's running it's

play08:57

mechanically linked to the engine it's

play08:59

going to pop oil as long as it's running

play09:01

so it doesn't matter if it's idling at a

play09:02

thousand RPM or going down the road 3000

play09:05

RPM is still going to blast oil

play09:07

pressurized engine oil off to the

play09:09

camshaft the cylinder head the rotating

play09:11

assembly and the Pistons uh now what

play09:14

they were talking about with the rich

play09:17

mixture

play09:18

fuel injected cars are way more accurate

play09:21

at metering how much fuel they need to

play09:24

combust compared to Old carbureted cars

play09:26

that in the cold you had to choke them

play09:27

and you had to worry about all kinds of

play09:30

issues with getting it the Run well and

play09:32

everything was mechanical and nothing

play09:34

adjusted uh completely different animal

play09:37

with the fuel injector car with a PCM

play09:39

and the IAT sensor and all these other

play09:41

sensors that precisely meter and add

play09:44

just the right amount of fuel to get it

play09:46

to run well and idlewale in the cold

play09:48

until it warms up so it's not like the

play09:51

fuel injectors are spraying 10 tons of

play09:53

fuel in here which gasoline is a solvent

play09:55

they're not spraying 10 tons of fuel in

play09:57

there it's not washing out your

play09:59

cylinders it's not washing your

play10:00

cylinders out getting in the oil

play10:02

diluting the oil

play10:03

that's not a thing we would be seeing

play10:06

lots of issues in the wintertime with

play10:08

engine failures with oil dilution

play10:13

um you know just all kind of things that

play10:15

we don't see in the wintertime because

play10:16

it's not a real issue they have taken

play10:18

something in theory and blown it out of

play10:21

the water so I think logically a minute

play10:24

about the combustion process your piston

play10:27

goes down pulls in the air fuel mixture

play10:30

comes back up compresses it spark plug

play10:33

fires Rams the Piston back down piston

play10:36

comes back up on the exhaust rope pushes

play10:38

the burnt gases out of the exhaust valve

play10:41

well

play10:43

if it's spraying too much fuel in there

play10:45

when the Piston's coming down for the

play10:47

intake charge and that air fuel mixture

play10:50

is getting drawn in

play10:52

when the Piston comes right back up

play10:55

is still being splashed and supplied

play10:57

with oil to lubricate that piston and

play11:00

the cylinder it's I think they're

play11:03

getting a little confused here I think

play11:04

they act like this is an old carbureted

play11:06

engine that just dumps fuel in like no

play11:09

this is a computer controlled system

play11:11

with variable inputs that monitor intake

play11:15

air temperature the air fuel mixture all

play11:18

this stuff and yes when you first start

play11:19

you are in open loop and you have to get

play11:21

closed loop when things get the

play11:22

temperature but it's not as bad as they

play11:25

make it sound on this article that I

play11:27

think they're trying to scare people a

play11:28

little bit here so that seems to be

play11:30

their main argument that you're going to

play11:32

strip away all the oil and the lubricity

play11:35

for your piston and your cylinder by

play11:37

letting your engine idle to warm up now

play11:40

what is the difference between letting

play11:42

it idle to warm up and driving it down

play11:44

the road that air fuel mixture is going

play11:47

to be just as Rich whether you were

play11:49

driving down the road or idling cold

play11:53

before you reach closed loop status

play11:55

so what's the point here I don't

play11:59

understand exactly where they're going

play12:01

with this because the oil pump is

play12:03

providing pressurized engine oil all

play12:06

throughout the engine no matter what RPM

play12:08

it's running at as long as it's running

play12:10

and that rich fuel mixture that's

play12:13

stripping away all the oil in your

play12:15

cylinders is going to happen whether you

play12:17

are idling the engine or driving the

play12:19

engine while it is cold and not to close

play12:21

loop status so

play12:23

non-issue completely here so that's the

play12:26

first thing I guess the second thing is

play12:28

uh they're trying to reach out

play12:31

environmentally and worried about

play12:32

pollution and you know letting it idle

play12:36

but it doesn't matter if it idles cold

play12:40

to warm up or if you drive it cold to

play12:44

warm up it's still going to be an open

play12:47

loop until it reaches closed loop when

play12:49

it gets to a desirable sufficiently warm

play12:52

temperature so again if it's a minute or

play12:57

seconds difference between it idling to

play12:59

the sufficient temperature or driving to

play13:01

that sufficient temperature is minimal

play13:04

so again not really an issue so it is

play13:07

funny that they mention for the EV

play13:09

owners that hey keep plugged up warm

play13:12

your car up till it's nice and toasty

play13:14

and feels good inside before you drive

play13:16

off make sure you don't use any of your

play13:18

precious electrical Reserve out of your

play13:20

battery to make yourself comfortable but

play13:23

you gasoline-powered Vehicles no no no

play13:26

you get the freeze and see your breath

play13:29

as you drive down the road you don't let

play13:31

the car warm up you don't get to defrost

play13:33

your windows yes you took the ice off

play13:36

but uh the cotton sensation fogged up

play13:38

Windows no you don't get to sit there

play13:41

until they defog where you can drive

play13:43

safely and see because you're polluting

play13:46

and damaging your engine you don't get

play13:48

to be warm and toasty when you drive off

play13:50

you better hope you have heated seats in

play13:52

the heated steering wheel because you're

play13:54

going to be freezing otherwise so that

play13:57

in itself is ridiculous the way they

play13:59

phrase that about the electric vehicle

play14:00

versus the gasoline vehicle

play14:03

electric vehicles are just not good in

play14:05

the cold the batteries don't like the

play14:06

cold they don't like to take a charge in

play14:08

the cold they don't like to maintain

play14:09

their charge in a cold and they

play14:11

discharge not the way they should in the

play14:15

cold there are lots of issues with these

play14:17

electric cars when it comes to the cold

play14:19

but that's not what we're here to talk

play14:20

about but what does the manufacturer

play14:22

actually State what does Subaru tell you

play14:24

to do about your vehicle do you need to

play14:26

warm it up and the answer is yes Subaru

play14:29

wants you to warm up your vehicle before

play14:31

driving if you've jumped into modern

play14:33

Subaru let's say 2011 2012 model year or

play14:36

newer you've started the car up and most

play14:38

likely seen the little blue temperature

play14:40

light so think about it for a minute

play14:42

when that blue light comes on when you

play14:43

first start your Subaru code your RPM

play14:45

shoot up to about 1800 maybe 2000 RPM

play14:49

and they hold there your engine's not

play14:51

just idling at 600 800 RPM your engine

play14:56

is idled up so it warms up faster that's

play14:59

when the blue light is on you are high

play15:01

idling warming up the engine in quickly

play15:04

but safely and Subaru states that when

play15:07

this RPM is high and the blue light is

play15:09

on to leave the car in park or in

play15:12

neutral with the parking brake on if you

play15:13

have a manual transmission

play15:15

you shouldn't be driving it while it's

play15:17

in its warm-up procedure until it

play15:20

sufficiently has warmed as they stay so

play15:22

there you go so in the article again I

play15:24

don't understand the whole idling the

play15:26

car is bad for it most modern fuel

play15:28

injected cars have a high idle while the

play15:30

engine is cold and the RPMs will drop

play15:33

once it is sufficiently warm so it's not

play15:36

really a big deal between letting it

play15:38

idle or driving down the road because

play15:40

it's still idling up to warm itself up

play15:43

faster than if it was just sitting there

play15:45

idling as the engine idles when it's

play15:48

already up the temperature which is

play15:49

normally between 500 and 800 to 1000 RPM

play15:52

depending on the engine make and

play15:54

manufacturer now that blue temperature

play15:55

light is an indicator of your engine

play15:58

being cold that light will turn off when

play16:01

the engine reaches a sufficient level of

play16:04

warmth it says at in the owner's mail

play16:07

that your engine should be warmed up

play16:09

that the blue light will go off when the

play16:11

engine is warmed sufficiently and that

play16:14

you should not drive until the car is

play16:16

that that sufficient temperature in the

play16:19

section of the owner's manual talking

play16:20

about winter driving it actually says

play16:22

that while you are warming up your car

play16:24

after you've removed any icer scrape the

play16:27

windshields to check free movement of

play16:30

your brake pedal gas pedal all of that

play16:32

stuff before setting out so again in the

play16:34

owner's manual it says before driving

play16:36

and while you are warming up your car so

play16:39

Subaru does want you to warm up your car

play16:42

before driving so aside for the selfish

play16:45

reason of our own personal Comfort why

play16:48

should we warm up our cars and it comes

play16:51

down to the mechanical side of it now

play16:53

with your engine your fluids need to be

play16:56

warm need to be warmed up before they

play16:58

start flowing well and protecting and

play17:00

doing what they should now that's more

play17:02

so in line for people that see like

play17:04

severe negative temperatures rather than

play17:06

if it's like 32 degrees outside your oil

play17:09

should flow as it should at that

play17:11

temperature when you get down negatives

play17:13

uh like teens and 20 is negatives that's

play17:16

when you have some serious issues and

play17:18

you should be running a block heater but

play17:20

you want your oils and your transmission

play17:23

fluid all that stuff to warm up before

play17:24

you start driving you want your engine

play17:27

coolant to reach about 100 to 120

play17:29

degrees Fahrenheit before driving uh

play17:32

it's just a good area that's

play17:34

sufficiently warmed up before you start

play17:36

driving down the road and another thing

play17:39

with the warming up the engine it comes

play17:41

down to your mail allergy your engine

play17:43

block your Pistons your crankshaft your

play17:46

cylinder heads all of this stuff expands

play17:49

and contracts with temperatures so you

play17:51

want to gradually get them up to a

play17:55

stable temperature of about 120 degrees

play17:57

before you start driving off so where is

play18:00

the most of the heat in your engine

play18:01

especially cold when you first started

play18:03

up is in the combustion chamber if you

play18:05

let it run for 30 seconds and start

play18:07

gunning it down the road you're going to

play18:09

put hot spots in the cylinder heads the

play18:11

cylinder heads are going to heat up

play18:12

faster than the block faster than the

play18:14

crankshaft the rotating assembly

play18:16

especially in a box or engine you want

play18:18

to let it all warm up gradually and

play18:21

together again 120 degrees Fahrenheit is

play18:25

where you want to get minimum-ish right

play18:28

around there before you start driving so

play18:30

with a Subaru it's not as big of a deal

play18:32

because your engine block and your

play18:35

cylinder heads are aluminum and they'll

play18:36

both expand and contract relatively at

play18:39

the same rates and same amount but think

play18:43

about this for a minute like in my

play18:44

Duramax diesel engine I have a cast iron

play18:47

engine block and I have aluminum

play18:50

cylinder heads that cast iron reacts

play18:52

differently than the aluminum to thermal

play18:55

expansion and contraction so it's

play18:58

actually more prudent that warm up my

play19:00

diesel engine before I warm up my Subaru

play19:02

engine because the Subaru engine has

play19:04

aluminum heads and aluminum block and

play19:06

they're going to basically react the

play19:08

same way to temperature variants whereas

play19:11

that Duramax Diesel with a cast iron

play19:13

block and aluminum heads both of those

play19:16

dissimilar metals are going to react

play19:17

slightly differently to temperature

play19:19

changes so again getting everything

play19:22

acclimated slowly as the temperature

play19:24

rises is better than just jumping in and

play19:26

forcing a lot of hot spots in around the

play19:28

cylinder heads and the Pistons and uh

play19:30

you know just not great for the car so

play19:33

the whole uh don't let your car idle to

play19:35

warm up because you're stripping away

play19:37

oil and going to destroy your engine

play19:38

compared to let it warm up for 30

play19:40

seconds and then run down the road and

play19:41

put hot spots in your combustion

play19:43

Chambers your cylinder heads and not let

play19:45

the whole engine acclimate to the

play19:48

temperature change slowly uh you know

play19:50

that's perfectly fine so again weird

play19:52

thinking weird logic in that article and

play19:55

the experts that chimed in on it very

play19:58

odd but again I'm no engineer so maybe I

play20:00

don't know what the hell I'm talking

play20:02

about maybe they got it right and I got

play20:03

it wrong but just thinking logically or

play20:06

at least my logical definition of

play20:08

thinking it seems that warming up your

play20:10

engine before driving is better for the

play20:12

engine than letting it run for 30

play20:14

seconds to a minute and end up going off

play20:16

down the road but that's just my opinion

play20:19

so guys what do you think let me know in

play20:21

the comments below do you let your

play20:22

engine warm up do you not let your

play20:24

engine warm up why do you or why don't

play20:26

you do you think it's dumb to let it

play20:28

warm up let me know in the comments

play20:30

below do you think it's dumb not to let

play20:32

it warm up let me know in the comments

play20:33

below thank you guys all so much for

play20:35

watching hope you enjoyed the video I am

play20:37

about to go into the house and get

play20:39

warmed up because I am freezing out here

play20:41

I'm sure you've probably seen my breath

play20:43

uh this video will probably go up on

play20:45

Saturday or Sunday Sunday being

play20:47

Christmas day Saturday being Christmas

play20:49

Eve so merry Christmas happy holidays to

play20:51

all of you thank you all for the views

play20:53

for 2022 and I will see you all in the

play20:56

next video
