Ya i agree. And you shouldn’t go too hard on it until it is completely warmed up. I used to think that was BS but one time I did a pull all the way to redline about half a mile into the drive and i heard a small pop and then the car started misfiring. I lost an ignition coil so it wasn’t anything major. I wonder if it was just ready to go and that was the last straw
Dave is a professional man with integrity . I will go with whatever he says . Val is beautiful and smart with a body to die for. Warm up your big truck, Val. ❤
Here in northern New York…many days you have ice on the windshield over 1/4” thick…2 minutes doesn’t do anything. When it’s well below zero….and leave before a 10 to 15 minute warm up…an Allison transmission doesn’t like to shift into its high gears until the fluid reaches certain temperatures . Not to mention you’re driving with thick oil with above average base pressure…as well as a cold transmission that isn’t ready to be pushed …especially a large heavy vehicle full of tools . Spend the extra 10 minutes warming it up and have a vehicle operating at more efficient temperature …these people saying warm it up for a minute and go don’t live in extreme cold conditions…or had their doors freeze shut and can’t open them….or the windows froze and won’t go down . Warm up your engines in extreme cold…it’s cheaper in the long run
The correct advice is start the engine, allow around thirty seconds of idling whilst the oil starts to circulate then drive off but don’t push the engine hard until it has warmed up. An idling diesel will clog up the dpf and catalyst, it’s better to get it working and it will warm up a great deal quicker. I am with Dave on this one.
I always let my 5 gas vehicles warm up at least to idle speed no matter the temperature or time of year I’m concentrating on the transmission as well as engine lubrication teaching my kids to do the same besides routine maintenance.
I was told in school no idle time is required. Since once the engine turns, the oil flows. Also “W” in oil stands for Winter not weight, to let you know the viscosity of it at cold start.
Well,here in New York state the windows get iced up pretty well,and there's a law that you have to have full visibility going down the road,so a good 5 minutes to get those defrosters going.
I'd warm it up a couple of minutes, but I'd also add to go easy on it initially. I like to accelerate slowly until I've at least run it through all the gears and preferably baby it until it's reached operating temperature. I think one of the worst things you can do to a vehicle in the cold is start it and immediately floor it.
Idling cause fuel delusion in oil and washes down cylinder walls. It has to do with piston speed and engine load effects on compression. At idle you have more unburnt fuel blowing by the piston rings. If you are sitting with engine running best to run above idle 1800rpm at least. Keep the diesel engine under load its best for. Dave is 100% correct
Gasoline engines you should let warm up. But diesels, especially new ones have very high pressure oil pumps that get the oil to the important parts of the motor very quickly, and as long as you aren’t reviving it out and pushing it hard before you are up to temp, you can start it and go, you shouldn’t let your diesel idle to long to begin with, it’ll clog up the filters, that’s why guys that have to install a high idle switch so I can keep the dpf and stuff hot while the truck is idling Dave is one of the best mechanics, and has done so much research for diesels and gas motors. He’s a worthy source.
If it’s a diesel, wait for the glow plugs to warm a bit before turning the key fully on, let it high idle for 30 seconds to a minute, drive like a normal person until it warms up. And I personally never shut it off until I’m done for the day but it’ll probably be fine if you do so long as you’re not gelling up.
I work on engines for a living. Dave is correct. Excessive warm up time is unnecessary. A minute is long enough. 3 minutes if you’re feeling generous. But of course… do what you’d like with your personal property lol
Warm up is no longer necessary. Start your vehicle, be it a truck, car, or van, and the RPMs will hit around 1100. Sit there until the idle drops to 900. This will take 10 to 30 seconds pending on the time of year. Put it in drive and go. As every rule has one, there is an exception. If you have a direct injection, let it run 30 seconds to 1 minute. If you want to know why, Dave has a short with a piston he will show you what happens when you don't wait to drive direct injection.
Depends why you are starting the vehicle. It's gets cold here. We often warm up the vehicles to clear the windshield AND warm up the vehicle. never a morning in the winter where I could just jump in and go.
Dave didn't say start it and hit it. Dave said start it up, let it run for a few seconds and drive slow and easy until it's warm. The idea is that it takes a warm engine to warm up oil. If the engine is idling for long times without the engine warming up, then the engine isn't getting the lubrication it needs for those long periods of time. The quicker the engine heats up, the quicker the oil warms up and circulates better. I let it idle for 2 minutes and take off, never going over 2k rpm until it's warm.
I agree with Dave. Even a gas engine. The correct way is fire up , let it idle 30 seconds and then drive conservatively until engine is warm. For Diesel if you are going to idle ,you better set the idle high.
I take Dave’s word over pretty much anyone when it comes to vehicles. If he says it’s fine for the engine then it is. The guy has engineered and rebuilt these diesels so much , he even has his own parts that are better than oem. He builds a better engine than ford Chevy or Cummins can from their factory.
Give it 30 seconds for the oil to circulate then drive it easy until it warms up, letting it idle to warm up just extends the amount of time you're running the engine cold and plugging up your dpf and intake manifold.
The oil pump can efficiently get oil to the top of the engine in about 2 seconds, so no need to warm it up at all. This statement does not apply to Alaska, where everything will gel.
Ive always let the idle drop down to operating rpm and then i drive conservatively not hitting boost until the engine is at operating temp has worked for me for years ive never had an issue
I live in Northern Ohio along Lake Erie, and I'll remote start my Silverado, as long as it takes me to put on my coat, grab my keys and walk out and get in. The fact it's a DoD motor and uses 0w20 means that oil is going to move pretty quickly.
Think about the expansion of all the different metals in an engine. They all expand and contact at different rates. There are engines that you will destroy not letting them warm up. There are also many engines that require a specific oil or it will again destroy them. The problem isn't the idling a diesel engine. Billions of hours are idled on diesel engines every year. It's the crap epa emissions garbage that is on the rigs. Get up north logging or on the drilling rigs (which I've done both) and they never shut off. Good luck firing anything up at 40 below without it being plugged in. You have about 45 minutes after it shut off depending on the wind.
Depends on the temperature if it’s -40 Celsius let it idle for 2 to 5 minutes then put it onto a high idle if it’s -30 and above start it idle it for 30 seconds then put it under light load don’t go flooring. Newer diesels hate idling and engines hate cold operation more heat you can put in faster the better. But honestly the best way to to have a coolant heater and oil heaters and some go as extreme as fuel tank heaters
Man this guys wild lol rigs idle overnight in the winter months here in Utah. It may not get as cold as it does back east but I still say you need at least a block heater to keep your situation situated lol
I can't believe this needs to be thought about in such depth, metal aluminum or iron expands at different rates to ensure that every part in the engine is lubricated and expanded properly it is best to get the engine to operating temperature. When an engine is cold especially here he in northern Canada where it reaches -50°C i have personally witnessed engines screaming bloody murder when not being allowed to warm up, the Power steering pump spewing oil because the oil is too thick.. and valve trains in V8-V6 engines are very noisy especially the push rod engines, how about the transmission? The oil pump and valve body takes a beating with the thick oil not flowing like it should, resulting in hard shifts and sometimes not shifting until high RPM's. I could go on and on about the benefits of warming up your rig in the cold before driving, in the 40 years of my life I have seen and done many strange things to vehicles in the cold, I have also blown a head gasket from rolling out of bed and driving my car down the highway in -30°C because I was late for work and my guess was that the aluminum cylinder head expanded faster then the iron block causing coolant to seep into the combustion chamber. I'm not telling you what to do with your vehicle, but if you hate it, don't let it warm up and build oil pressure it's a sure fire way to have issues with literally everything down the road lol.
Id like to add for gasoline engines at max you need 1 minute then drive it like your in-laws grandparents are with you until all your temps come up don’t forget your transmission is a hydraulic system that oil needs to also warm up differentials right beside them once it’s warm have it a go
He’s taking about light duty diesels medium and heavy duty are treated differently. They have a higher average load factor than lighter duty diesels which means they are stressed higher
Give the engine some time to circulate the oil. Even when you get up in the morning,it takes you a little while to get your blood going. No difference.
I have a problem with that. I’ve been a mechanic for over 35 years. It takes a long time to get oil up to the heads when it is cold. Not to mention diesel engines require heat to run. No disrespect to Dave I know he knows his shit. Maybe I will just get rid of the dpf and the egr and run it like my 7.3
Honestly? Take it as Pascal's wager: what's the worst that can happen from waiting 2-4 minutes? And what's the worst that can happen from not waiting? And let's assume you are consuming 1.5L/h for idle... You consume 25 ml for the time you idle...
Clearly never experienced-40. That diesel is equipped with a high idle specifically for that reason. If it’s going to be idling then set high idle and it shouldn’t cause issues. However if your starting a diesel and idling for 10 minutes and driving 2 blocks to work and repeatedly doing this without long trips you will definitely have issues with your dpf filters and emissions system. It’s good practice to start your vehicle and wait till the rpm’s come down on their own. That’s you vehicle saying it’s warmed up and ready to go
The new trucks with the crap exhaust, no you should not let them idle, just don’t drive them hard until the oil is warm, old trucks you should absolutely let them warm up first.
Do what you want. Me personally if your engine is still in idle up from starting then you shouldn't be driving it yet. Imo I let it sit a few mins and idle down and get the fluids going. It's not just oil but also your transmission fluid heating up a little and building pressure so I'm sure you can start and go but my family don't.
Idling for longer times increases time baring surfaces are poorly lubricated, it is better on modern cars to let them warm up for a minute and then drive them low rpm to raise the temperature quickly and reduce time spent with poor lubrication
Idling isn’t the problem people don’t do parked regens rolling regens only get to 700 degrees but doing parked regens get to 1100 most people don’t drive 3 hours straight which is needed for proper rolling regens. Do your parked regens about 1 a month and you will be 100%…
It depends how long you want your engine to last. I never drive my 09 dodge ram until it’s at least 145°. I have 1,900,000 miles on this truck, And I’m driving it right now.! So, there is your answer. 145F then drive.
Well I would agree with him if he has it plugged into a block heater, if thats true then yes, and if your tool truck doesn’t have a block heater being where your at and your not using it then yeah sit there and idle for 10 minutes
Well here is the truth. When the engine idles back down to normal idle it is then ready to drive most gas cars cold start and idle at 1000-1200 rpm's for about 1-2 minutes when they idle back down the ecu recognizes optimum operating parameters same thing goes for diesels
I've always let my trucks idle for about 10 minuts and I live here in Wisconsin. I've never and will never just get in and go especially in the winter.
Omg watch his video. Your talking about old disels. New disels don't need long warm ups. Need things change,you need to learn again and adapt with times...
Anything with electric fuel injection should not be warmed up. Why would you want an overly rich fuel program to run longer? Why would you want excessive blowby allowing fuel to be introduced to the oil thinning it out because the rings haven’t fully seated until the engine is warm? Engines are designed to run at operating temperatures for a reason. As soon as the oil pressure light is out it is safest and most efficient to drive the vehicle. The thought it was ever believed to be better to warm the engine is baffling to me. That’s not how engines are designed and never were.
Honestly, I’m listening to Dave
What I say common rule thumb is let the high idle come down and you’re good so 30 seconds you’re good to go
Ya i agree. And you shouldn’t go too hard on it until it is completely warmed up. I used to think that was BS but one time I did a pull all the way to redline about half a mile into the drive and i heard a small pop and then the car started misfiring.

Do what you want but at -10 I want some heat in the truck and there are places that out west that get - 40 and colder. I bet they let it warm up too b

I was told in school no idle time is required. Since once the engine turns, the oil flows. Also “W” in oil stands for Winter not weight, to let you know the viscosity of it at cold start.
Bingo! Before you can even get it in gear the oils flowing. If it took that long to get it flowing, we'd be replacing engines every 25-40k miles.
Lmao so if u pull out the water bottle from the freezer you would instantly drink it because the ice flows in the bottle? @@garrettkifer8332
@ definitely be destroying some lifts n rods pretty quickly
Well,here in New York state the windows get iced up pretty well,and there's a law that you have to have full visibility going down the road,so a good 5 minutes to get those defrosters going.
Dave is correct however I start mine up because I don’t like driving to work in a cold truck
I'd warm it up a couple of minutes, but I'd also add to go easy on it initially. I like to accelerate slowly until I've at least run it through all the gears and preferably baby it until it's reached operating temperature. I think one of the worst things you can do to a vehicle in the cold is start it and immediately floor it.
In Michigan. Delete the bad system and idle all damn day keeping my tools warm.
Dave is correct. It’s not the engine and related components that need warmed up, it’s our asses.
Coolant heater/block heater,and oil pan heater. Plug up your diesels to make them last
Then you can crank it up and go
Go with Dave he knows his stuff.
Stick to the tools val . Dave is one of the best in the business .
Depends on your Vehicle Requirements and Location imo

How cold is it??😊😊

Living in MN, people treat their vehicles like a living thing. It’s a machine. Start it, and go EASY. Better overall
Besides warm up, after a long trip should you let the diesel idle to help your turbo cool off?
Give it 30 seconds for the oil to circulate then drive it easy until it warms up, letting it idle to warm up just extends the amount of time you're running the engine cold and plugging up your dpf and intake manifold.
I let mine idle just enough to let warm fluid to the heater core.
Warm cabin
The oil pump can efficiently get oil to the top of the engine in about 2 seconds, so no need to warm it up at all. This statement does not apply to Alaska, where everything will gel.
Listen !
Key words. Warm up "BEFORE" start it.
Let glow plugs warm, start, idle couple min, and go.
This is true idling ls bad for all vehicles. It will warm up faster under load.
I feel the same I let my my 2015 ford 1 ton run for a few minutes for sure before I take off and yes it’s the powerstroke
Ive always let the idle drop down to operating rpm and then i drive conservatively not hitting boost until the engine is at operating temp has worked for me for years ive never had an issue
Dave specifically talking about diesels idling clogs intake runaways

If Dave said it then it’s right
Dave is completely correct
Dave is right everyone else is stupid and does it because that's what they told me to do they can't think for themselves
Rob the mechanic also said. "Long enough for you to put your seat belt on" for the first 5-10 minutes just drive normal
I see lefty stands a little more firm than righty,they are great either way😁
I have a gasser, but I let it warm up for my comfort. I don’t wanna be halfway to work before I’m not freezing half to death.
as long as you let it regen and not shut it off in the middle of a regen its fine and im a master diesel tech
I’ve still got my 7.3 so no exhaust system to clog 👍
Depends on the Quality of OIL
Your Useing...
It gets -30 and 40 up here every winter, you need to warm them up especially diesels better yet install a diesel coolant heater
I live in Illinois it gets crappy cold I let mine run for at least 10 minutes🛠
Let it warm up. Or if possible make sure to use a block heater
Id like to add for gasoline engines at max you need 1 minute then drive it like your in-laws grandparents are with you until all your temps come up don’t forget your transmission is a hydraulic system that oil needs to also warm up differentials right beside them once it’s warm have it a go
You can idle as long as you want ….. IF …. you want that sootie crap injected back into your intake and turbo.
Dave is right!
He’s taking about light duty diesels medium and heavy duty are treated differently. They have a higher average load factor than lighter duty diesels which means they are stressed higher
Turn it on an go no idling needed
Give the engine some time to circulate the oil. Even when you get up in the morning,it takes you a little while to get your blood going. No difference.
Depends on the year and state of the vehicle if it’s old I let it idle for 10 to 15 min newer ones 5 minutes
I have a problem with that. I’ve been a mechanic for over 35 years. It takes a long time to get oil up to the heads when it is cold. Not to mention diesel engines require heat to run. No disrespect to Dave I know he knows his shit. Maybe I will just get rid of the dpf and the egr and run it like my 7.3
Honestly? Take it as Pascal's wager: what's the worst that can happen from waiting 2-4 minutes? And what's the worst that can happen from not waiting?
And let's assume you are consuming 1.5L/h for idle... You consume 25 ml for the time you idle...
You remind me my mom. She was the smartest person in the room and just happened to be the best looking.
Thin oil don’t worry about it 5w40 or more let it warm for a few that’s my opinion
Clearly never experienced-40. That diesel is equipped with a high idle specifically for that reason. If it’s going to be idling then set high idle and it shouldn’t cause issues. However if your starting a diesel and idling for 10 minutes and driving 2 blocks to work and repeatedly doing this without long trips you will definitely have issues with your dpf filters and emissions system.

Let it idle. You want the oil to warm and run through . Always let it idle at the least of one minute.
The new trucks with the crap exhaust, no you should not let them idle, just don’t drive them hard until the oil is warm, old trucks you should absolutely let them warm up first.
All I know is…if freezing my ass off is the only way to keep a new truck from blowing up…I’ll let my warranty handle it. This is getting out of hand.
It's better to warm up by driving idling is not creating enough flow just don't push it hard until you hit operating temp
If its not carbureted u dont need to warm it up u can if u want to but u dont NEED to
Do what you want. Me personally if your engine is still in idle up from starting then you shouldn't be driving it yet. Imo I let it sit a few mins and idle down and get the fluids going. It's not just oil but also your transmission fluid heating up a little and building pressure so I'm sure you can start and go but my family don't.
As soon as I see oil pressure in my gas engine I'm out of there 325,000 on my suburban and still running strong.
Idling for longer times increases time baring surfaces are poorly lubricated, it is better on modern cars to let them warm up for a minute and then drive them low rpm to raise the temperature quickly and reduce time spent with poor lubrication
Idling your truck for long periods. More than 5 minutes is technically bad for it you want to idle around 1200 RPM
I'm called Dave and all Daves are right. Val seems OK though. Oooooooosh
Idling isn’t the problem people don’t do parked regens rolling regens only get to 700 degrees but doing parked regens get to 1100 most people don’t drive 3 hours straight which is needed for proper rolling regens. Do your parked regens about 1 a month and you will be 100%…
It depends how long you want your engine to last. I never drive my 09 dodge ram until it’s at least 145°. I have 1,900,000 miles on this truck, And I’m driving it right now.! So, there is your answer. 145F then drive.
I always plug my block , oil and trans pan warmers in when I'm in exsteme cold
8 believe dave is references the def system which hate idling
Warm it up before you start it. That’s hard to do unless you have a garage
Negative. These oil pumps now are amazing. They have almost instant oil supply.
Let the oil warm up a bit and circulate
I don't give a crap about the truck. I start it and let it run till it warm enough.
You can go, just don't drive rough for the first couple minutes and all will be fine.
Non def systems... i would say let it warm up, gasers let it warm up... diesels with def IDK
Plug in your diesel and keep the oil warm.
Crisis averted 😂
The manufacturer is the go too
Mine sits and warms up for 5-10 min every morning my newest car is 18 years old I’m gonna let it warm up and build some heat before driving
Well I would agree with him if he has it plugged into a block heater, if thats true then yes, and if your tool truck doesn’t have a block heater being where your at and your not using it then yeah sit there and idle for 10 minutes
I always wait for it to idle down
Well here is the truth. When the engine idles back down to normal idle it is then ready to drive most gas cars cold start and idle at 1000-1200 rpm's for about 1-2 minutes when they idle back down the ecu recognizes optimum operating parameters same thing goes for diesels
Truckers are with you, I keep my semi at least 30-45 minutes at 5 degrees temperatures. 2 milion miles later, truck still runs well
No idle..Icon.idle book
Wait at least until the MAF kicks in
Idle for 3 min. Missouri check in
I've always let my trucks idle for about 10 minuts and I live here in Wisconsin. I've never and will never just get in and go especially in the winter.
Omg watch his video. Your talking about old disels. New disels don't need long warm ups. Need things change,you need to learn again and adapt with times...

Why would you want excessive blowby allowing fuel to be introduced to the oil thinning it out because the rings haven’t fully seated until the engine is warm? Engines are designed to run at operating temperatures for a reason. As soon as the oil pressure light is out it is safest and most efficient to drive the vehicle. The thought it was ever believed to be better to warm the engine is baffling to me. That’s not how engines are designed and never were.
