Modern cars,have very fragile engines ,so even if you dont warm the engine,you shouldnt start with high revs until the engine is at normal operation temperature .
simply ad 100-200rpm on ur feet to warm up faster no risk on winter* but summer i drive after 10sec there no problem
In modern cars, you shouldn't ever wait for your car to reach its operating temperature. But in -20C (-4 Freedom Celcius), you definitely want some warm-up before driving. When it's below freezing, general rule here is to put the block heater on (if you have one) for ~30min to 1h before driving off and let it idle for a minute or two while clearing all the snow and ice.
Of course you should.
Just warm-up today means something else.
Start up engine, buckle up (in Winter maybe setup radio:)) and you free to go, but you should drive gently. Low rpm.
Oil needs to warm-up.
I just follow Engineering Explained's advice from 10+ years ago. Let it sit running for 10 secs for the oil to fully circ before driving away steady. If you are planning to stop for more than 7 seconds, it is more efficient to turn off the car. What that guy can do with numbers & research is biblical.
Yes, this is true for your engine. However, the reason to still do this with modern cars is to warm up the transmission, which does make a difference.
That is a good point nobody talks about.
that true* i seen alot ppl did horribly reset dsg meanwhile tranmisssion is not hot enough... because alot idiot YT explain how to reset whitout explain first u need to warm up to do that trick...
Under normal conditions modern car warm up very quickly
I live in a mountainous region some of my customers have to drive hard uphill directly after starting others downhill in both cases I recommend warming the engine and when it's extremely hot I always recommend Leaving the engine running for sometime before stopping😊 Back in the day we used to Call this running the engine down Some modern cars have an electric water pump which runs after stopping for the same reason
I like your recommendation on cooling engine back down! Definitely recommended for turbo engines especially.
Not true. Engines take 5-10 miles to reach operating temperature
@@PointNemo9 I can drive 15 minutes downhill from where I Live and still have a cold engine when the car is moving there is a lot of cooling
If I drive up I start with a 20% gradient one and three
Firstly, it's 100% a bad idea to start an engine and let it idle up to operating temp. But, modem engines (as stated in the video) should at least be warmed up until the fast idle drops down.
I only use remote start for my 22' Maverick in the summer so i don't have to press the brake pedal when i get in. Just one press to activate the keyless ignition. In the winter, I notice there's sometimes a very fast idle then a normal fast idle, so that's when it's great to use remote start.
Lastly, modern engines have a lot going on and should be slowly warmed up a little bit. Especially if you're towing \ hauling or driving uphill right away.
@@Aaron_Voltz thanks for your input 👍
Even 70's cars only needed full choke for 10 seconds or so, then you could drive away.
It’s not a myth. In old cars it really is true.
@@robertgary3561 I state that in the video ;)
Our car is a PHEV with several settings that allow you to determine whether / when the vehicle runs 100% on electricity or in combination with the petrol engine. Think pure e-mode, normal mode (alternating between e-mode or combined) and sport-mode (with emphasis on the petrol engine and less frugal torque from the electric motor) When accelerating while getting on the highway, for instance, the petrol engine kicks in, revving fairly high, without warm-up time and without the luxury of running idle for a couple of minutes. What's the best thing to do or be mindful of in that scenario?
I was thinking the same thing
A great question! The only thing I can suggest is pressing the accelerator enough for it to kick on in a non aggressive way .This is being picky. But the internal combustion engine doesn't work nearly as hard or log as many runtime hours as a non PHEV. So it is not as important.
Thanks @@MikeMDs Makes sense although that isn't always possible depending on traffic. In normal circumstances I try to accelerate all electric until I reach cruising speed and then switch to normal or sport.
Cars should not be equipped to do high revs on cold starts. Those in cold countries can rev up to get to operating temp. If there's a way, I would disable the function. I would idle the engine for about 20s before driving off slowly
In winter yes (like with choke valve for minute).
When your car sits outside overnight in -35 degree celsius cold it needs warming up several minutes before driving it. If you don't you will over time cause damage to your engine. That's just common sense.
This subject varies dending on your application and weather.I usually just listen /feel the car out to see what suits it.Also don't forget the
trans fluid.In the winter, i have to let it warm up for a few mins or the shifts are terrible .
Great suggestion!
Well, I usually let the coolant get to temp for about 5 to 8 minutes. If I'm in a hurry then I just let the engine get oil circulation and keep the revs low.
First and most important thing to do when turning the car ON is pressing the throttle at 100% and keep it pressed in neutral for at least 10 minutes. Second most important thing is to drive it in 1st gear for first 30 minutes... After that, drive it as you want, but don't forget to repeat the first step before turning the car off!! source: trust me bro
For turbo cars u do
Hi, I've got a question about my 2.0l L4 petrol engine with a turbocharger, over 300 horsepower, awd and forged pistons & camshaft with direct injectors. (All stock, no performance tuning ever installed)
In my underground garage it is 10°C in winter an 20°C in summer.
As soon as I start the engine I turn of the start-stop nonsense immediately.
The idling revs are 1'500 rpms for about 10 - 20 seconds then slowly decrease till after about a minute they fall to 800 rpms at 36°C of the engine oil.
My question is: Are 10 seconds waiting enough to drive gently out of the garage? (I have to drive up a ramp to get to the street level)
Or should I wait till the rpms are down to 1'000?
Thank you for your time, peace! ✌🏻
Thats still pretty cold in the morning. Technically you can drive off after the 10 seconds. But If it were mine I'd wait a little longer if you plan on keeping your car for the long haul.
@@MikeMDs Thank you very much for your answer. So should I wait till the rpms start to decrease? The engine oil is then about 27°C warm.
If you have an oil temp gauge then it might take a long time to see temp changes compared to coolant temp changes. I say just let idle for one minute when it is cold and drive off.
@@MikeMDs Ok, I can see the Oil- Water- and Transmission Temperature on the display in the middle. They are very accurate.
One minute? Ok, that's what I thought. But isn't there going to be problem from carbon build up? Or won't there be any cause i have direct injectors?
Carbon build up is mainly from driving style and fuel quality. Lots of city driving and traffic is the main culprit for carbon build up. 👍
Does a CVT transmission need warming up?
What is with all the BMW advertising LMAO
I am a BMW specialist and most of my content for how-to is on BMW. For my usual subscribers , I try and keep it somewhat BMW for topical videos like this as to not loose them as a subscriber. What else would you like to see? Are you a subscriber?
