Is there any practical benefit to letting a passenger car oil warm up before driving?

At least around here the air is usually very dry when the temperatures are low. This means that my breath is usually absorbed into the air well before reaching the windshield.

Maybe you’re more full of hot air than me :D
Probably.......throw in 2 kids and wife....
We always warm up for a few mins before a family take off.

Also we live in a valley, lots of heavy frost on the windshield almost every morning.

A bit of heat makes the job 1 million times easier.

I warm up most of the winter.
 
I "debated" this elsewhere with someone and finally asked them where they park and where they live. They live in Dallas and park their car in a garage.
They should come up here and park their car outside tomorrow morning and I will watch them drive off after 10 seconds or whatever all the experts say! I killed 3 kids in the crosswalk, but I saved $0.20 in fuel and it didn't get into my oil so its worth it?

Seriously right......they have absolutely no idea what it is like in frigid climates.
 

-25 C start this morning. I let it run for about 15 minutes before heading out. Accessory drives sound very unhappy.

Thanks for sharing. What oil are you running?

Also why is the speedo telling you you’re doing 120+?

Speedo has been broken for years (instrument clusters almost always fail on this generation of truck), I just use torque pro on an old phone and I get to see speed, coolant and transmission temperature, fuel trims etc.
Oil is Mobil 1 0w40. When it's this cold there is no engine noise for the first 60 seconds or so then it has a slight tap for maybe 10 minutes at idle.

Exactly what my 2005 Silverado gauges looked like. The final straw was loosing the fuel gauge. Was trying to find the company that fixed the cluster but like new now with all new cluster step motors and changed the LED’s to green. About 125 bucks.

I was going to do that, but I need to record mileage for work. I will have to deal with it when the fuel gauge goes as there doesn't seem to be a way to get it through obd.
 
i do 60 seconds warm up in summer and 30 minutes warm up when it is below -40 celcius. this morning, it was -44 celcius without wind chill. -47,2 Fahrenheit in chibougamau, quebec, canada. it is impossible to do start and go. first, your vehicle has to start. try starting an unplugged vehicle at that temperature. second, if you manage to start, the rpm is at 1800-1900rpm and does not want to go down for at least 30 minutes.
Thats total BS nonsense. I have lived in cold climates all my life. No computer controlled engine is going to sit revving at 1800-1900 rpm for 30 minutes. More like 1500 rpm for 2 minutes then down to a normal idle. My 4.8 V8 had no troubles starting in Thompson MB. None. My Ranger 4.0 had no issues either.
 
With a standard passenger car, toyota camry, is there any mechanical benefit to letting the oil warm up in standard midwest winter, 10 - 30F, temps? When doing an oil change I noticed oil at operating temps runs out like water. About an hour later when draining the oil collection pan at 50F garage temps I noticed the oil ran like maple syrup. This is using a 5 30W synthetic oil. When it gets down to 20F I would imagine it runs even thicker. I am thinking that the car is designed to run best at stabilized operating temps where the oil runs like water. How much, if any, does the extra thickness of 20F oil wear the engine? Standard practice with fuel injected engines is they don't need any warm up but is there any benefit to letting the engine come up in temp just a bit and give a minute or two to warm the oil up to 100F or so?
Decades of Upper Midwest car experience in temps -20 to -35 °F. Always used synthetic in the winter, didn't use a block heater, never had issues. When it was below zero and the car had been sitting for a few hours, I'd let it idle for a few minutes (probably about 5) because otherwise clutches on manuals didn't work well and you'd grind the gears sometimes. On the automatics I had they'd be super sluggish at first, too. I'd sometimes take an extra loop or two through residential just to be nice. But never an issue. All the engines had well over 200k when I got rid of the cars, minimal oil burning, etc.

Long story short: drive moderately at first and I doubt it matters much.

Or in the case of my Jeep Wrangler ( 3.6L ), it's @ 12-1400 rpm for about 20 seconds before it settles down into the 700 rpm range. I don't know if these are still widely used, but when I lived up north ( Northern Michigan, and Maine ) I had electric engine block heater units. It would heat and circulate the coolant as well as the engine block, presumably hot enough to keep the thermostat open . . . go out in the morning, unplug the car, start it up and you had a head start on scraping the snow/ice off the windows.
 
The other morning it was 2 deg. here. By 10 AM it was 8. I decided to go and start the car and let it warm up. 3-5 minutes later the RPM was still pretty high, about 1200 I would say. I didn't wait any longer, but I got heat by the time I was 200 yards down the road. I don't think you harm your car by warming it. Maybe you waste some fuel. But that is a small price to pay. Its like the guys who change their oil at 20k, to squeeze out every penny. It's just not worth it. Now, on my way home from work, I start the car, wait about 30 seconds and I drive. Its a balance. Its not practical to sit in the garage at work 3 minutes...but at home, I don't mind starting the car and waiting.

That’s a bit of an angry response sir
 
I have to agree with him though. My cousin lives in Alaska and even in -40*F weather, it never takes more than a couple minutes for the engine to idle down. Once the idle comes down, that's the ECU saying there's sufficient heat in the cylinders for fuel vaporization and efficient combustion, the fuel trims are dialed back, spark is advanced more, and it's ready to drive. By the time he gets out of his neighborhood, there's enough heat in it to turn the heater on.

I guarantee the increased soot from poor idle combustion for 30 minutes is contributing far more to wear than just driving the car with cold oil. Plus there's the wasted fuel.
