Warming up the truck still necessary?

Huh, somehow my posts survived..... Anyway, as long as it take for my hand to reach the gear shift from the ignition is how long I warm up for. In bad weather I were gloves and scrap the windows, then take off. Water temp on my scan gauge doesn't even take 2 mins to reach 100+ degrees F.

 

mine got deleted all i said was dont feed the trolls , i did learn something from posting this thread , i just let the truck warm up for 30seconds seems good enough

 

The older cars needed warming up...and by "older" I mean the ones before Electronic Fuel Ignitions (EFI)/Carburated/With some kind of choke.

10 minutes sounds about right to get the cabin nice and toasty and the engine idling at around 800 RPMs; down from around 1200-1500.

But the question is for 3rd Gen Tacomas.

I've learned that once my console display (I mean the one in front of the steering wheel & the touch screen) I can feel confident in putting her in "D".

I don't press the gas pedal immediately...I let her slowly ease through the driveway in gear and then once I'm off the curb/driveway, I go on my merry way!

 

it's fuel injected and. also have to in my Land Cruiser. That takes forever to warm up.

 

It's true that old dogs can learn new thangs!

 

I'm trying to recall my reply from 2 years ago!

Thread revival!

I'm 58.5 years old and and still the youngest at the J.O.B.

 

I heard both sides of the story many times and I realize that this is new generation materials and the like, but ....
I'm the old fashion, warm-it-up type.
In-laws say no warm it up, but I was trained in the Type 1 VW bug school of thought.
John Muir of "How to keep your VW alive ......." is my source.

When and if you re-build an auto engine, your appreciation for how it functions increases incredibly. AND ALL OF THOSE PARTS ARE LUBRICATED BY OIL ! You change your thinking and want oil on everything. How it all fits together and gets its OIL is really cool. When you pick up a 20 lb crank and bolt on the rods - you're amazed that oil is what helps keeps it from flinging by your head.
That's a lot steel moving around at a very rapid pace.
Let alone do the engine parts get lubed, but all the metal/steel gets to its 'operating size' and 'position' its designed to do/be for operation.

I want my parts lubricated and up to the proper size, as much as possible, before it has to bear my loads. I want to be warmed up and lubricated before I got to do a job. Hmmmmm ....

He maintains:
1) Says that WIU is the best thing you can do for your engine.
2) 90% of engine wear occurs in the first 15 min of operation in the AM.
3) 1/2 to 3 min - colder the longer WIU.
4) Start off slowly and increase gradually.
5) when not in use, oil drains from the cylinders and operating parts.
6) WIU lets the oil splash up in to the cylinder walls and on the other oil-able parts.
7) WIU lets the splashed oil bear the weight and movement of the engine parts, not metal on metal.
8) says that it increases engine life by 1/3.

I've rebuilt 3 VW engines and was amazed that something like oil allows all the cam, lifters, crank and rod throws, pistons sliding in the cylinders sliding to actually WORK. All those tight parts moving n harmony! That's a lot metal moving around

SO, you choose - start cold or warmed up. Why do athletes need to warm up before an event? Why do cars have thermostats?

 

So the engine will get to operating temp quickly and stay there. It's not getting to operating temp quickly idling in the driveway. All you're doing is wasting gas and soaking the converter with unburned fuel

A point of consideration.. The sooner the engine gets to temp the sooner the fuel will atomize and turn to vapor as it enters the cylinders. If you have a cold cylinder the fuel will want to resist vaporizing and stay "liquid". Liquid fuel will stick to the cylinder wall resulting in increased wear as the piston rings scrape up and down.

The days of carburetors are long gone, modern fuel injected engines don't like running around luke-warm. That's why the computer will code if it sees the engine not running hot enough.

I wouldnt listen to that asshat

 

Oh.. it's Friday. It's easy to imagine someone mechanically challenged would interpret the "no warm up" advice as permission to bounce off the rev limiter seconds after startup.

 

Well he knows about 10,000 times more about cars in general than I do.
I tend to listen to those who are smarter than I am.

 

I confess, I did not read this entire thread, but,

$52 0w20 oil Toyota/ exxon mobil Case of 6 Quarts Full Synthetic TGMO SN 0W-20 Oil

0w20 oil.
Its at 0 weight when cold and when up to operating temp is at 20 weight.
Do you want to start and load your engine while the oil weight is at near 0 weight?
Let it warm up. Or don't, but please do post how your early rebuild goes..!

 

I'm no mechanic but I can't imagine warming up the vehicle is going to hurt anything. Ultimately you want to oil to move better throughout the engine and that obviously isn't going to happen when the oil is cold as it will move slower throughout.

 

You people overthink way too much shit.
Your heads are full of chaotic synapses.

 

Well said but this thread is way beyond chaotic synapses. It was started over 2 years ago and has over 220 posts. It was a simple and dumb question , one or two responses would have completely answered it. To make things worse the op is a jerk and asshole. I only say this because one of our mods wrote a long dissertation about what a jerk he is when the op was banned. Not a 30 day ban but the dude is permanently banned. He’s not even around to see the posts.
I’m not going further down the rabbit hole in this discussion. I was #10 post in this thread. I’ll stick with that answer. I’ll end by saying if the owner’s manual doesn’t say you need to warm up your car then you probably don’t need to warm it up.

 

I let mine warm up for a few mins, because being cold sucks. And I live in a very cold weather state.

 

I like to wait 10-15 mins in winter.

In summer usually 5 mins.

Its just as athletes do warm up before actual exercise, especially in cold. Can't say it will hurt or not hurt to drive off right away, but this is the correct way in my opinion.

 

It is your truck and your money, and this is what I do with my vehicles: during the summer the ambient temperature could be from 50 to 70 degrees, so when I start the engine (cold start), the ECU kicks it into high idle, then in a couple of minutes the RPM comes down to mid-idle, and a minute or two later it drops to normal idle speed; that's when I drive it. If the temperature is around 30 degrees, I let both the engine and the cab warm up before I drive the truck. It also gives me time to scrape the ice from the windshield and windows. If it is -20 or even -30 degrees, I let it warm up even longer before I drive.

If it is colder than -30, I don't drive unless there is an emergency

If the temperature is -10 degrees and colder and I arrive to the supermarket to buy groceries, I keep the engine running with the remote starter to keep the cab warm enough for the produce (tomato, avocado, lettuce, flowers for my wife-for example-and so on from freezing. Also, if I am taking photos of the Auroras, my truck's engine is idling while I take some photos a few feet away from the truck, then I get in the cab to warm up, then out to take more photos, and so on. It could take from 1 to 4 hours of idling. By the way, if you drive a diesel truck in the winter, you already know what I am talking about.

Yes, the EPA and others will tell you that it makes no sense to warm the engine of a modern automobile, right? Even some (not all) automobile manufacturers will tell you warm it up for just a few seconds, and the reason for this is that letting the engine idling burns fuel. It does not look good for the truck in the CAFE standards. That's another reason for using 0W-20 and thinner oils these days; better fuel mileage.

 

30 seconds or so after start, and I’m in drive or reverse and moving. If really cold, I remote start with heater on, but not needed most of the time.

 

I had a neighbour kid back in the day that had a Datsun 240Z.
Many extreme cold Canadian Winter mornings he would be asking me to boost his car. We always struggled to get it going and I would offer to give it a shot of ether. He would flat out refuse due to the damage it would cause.
When we would finally get it started without the ether he would immediately rev it to about 4,000 RPM within a second or two of firing.
