For the sake of my comfort I'll warm my car up a few minutes. Just remember when your oil is super cold it doesn't flow properly and idling makes that oil take longer to get to the proper operating temp to lubricate.

not saying this is correct, and ive heard that it only needs about 30 seconds to ready to drive, but i wait til the needle hits the first hash. year round. thats just me. plus when you take off with it cold, you hear that annoying throw out bearing whine.

 

I wait tell i hit 108 degrees f, the. I keep it under 2500 rpm max tell i hit proper temp

 

Why 108?




I always let my car warm u p for a while when it's really cold. It can't hurt.

 

I get in car
Turn key on
Wait for needle sweep
Hear fuel pump
Start car
Put seat belt on
Tune radio to am station
Turn seat heater on

Get on the road
I keep it under 3k till 175 F on the trans oil

 

This is almost exactly me too...........

If there were some "limits" as to how hot the oil had to be, or how cold is too cold to drive, or time-of-warmups, that need to be followed for this car, they would be in the owner's manual. The only thing in the manual is this:
"NOTE
. Avoid rapid racing and rapid acceleration
immediately after the engine
has started.
. For a short time after the engine has
started, the engine speed is kept high.
When the warm-up is completed, the
engine speed lowers automatically.
. On rare occasions, it may be d"

Note that the first bullet is assuming you start driving immediately after start! It says to not do rapid accelerations immediately after start; it does not say 'don't drive until so many minutes after start.'

 

Is it Really Necessary to Warm up Your Car in The Morning? | Hillmuth Certified Automotive

 

108 is when my idle drops

 

Ahh ok, I see. I thought maybe it was just a random number you chose, haha.

 

I usually wait until 170f before going into boost. Want those bearings to last as long as possible.

 

Haha no its when my idle drops, and my heater on auto starts blowing. I figured it was the car saying "im ready"

 

Sometimes. All depends on how late i am Now that I got this frost thingy for my windshield from the Mrs mom for christmas, i've been extra slacking.. Usually i'll let it sit for 5 minutes ish, just because my drive is just over a mile... Otherwise the car will never warm up. My idle drops at 107.6. lol

 

I just turn it on, give it a kiss, and wait about a minute.

But...

That's my own thing...

 

I just wait until the triple meter in the center console actually starts registering the oil temp.
It starts at '- - -' Usually it's 2-3 minutes in Michigan winter.

 

I start it up, listen to it run for a few seconds (old habit from a time when I needed to make sure my engine sounded "right" before going anywhere), then drive VERY gently through my neighborhood, at which time the needle is beginning to move. I keep revs under ~3000rpms until the needle has cleared the first mark.

Unless it's somewhat colder, like this morning. I let it run in the garage, and get the seat nice and warm, before I hopped in and took off.

Pretty much this.

 

Try lectures on MP3. There are entire courses freely available on YouTube for example. Anyway, I don't warm the car up. I drive the car mellow not only because that's what the manual says, but also because I live near other humans that may still be asleep. By the time I'm on the main road the car is warm. Done.

 

So what?......the general conclusion here is that we are more concerned with our butts warming up than the car?

 

Not in a base model

 

Basically yes. I've heard pros and cons of it for decades with little hard evidence it lengthens or shortens engine life.

I know they say modern cars don't need to be warmed up in the morning but.......I turn the ignition on, wait for car to cycle, start it up and let it idle till AP says coolant temp is at 100 degrees and drive off. I keep it below 3K rpm till the engine is up to temp.

 

I turn the key to acc, let the pump prime, then fire it up. I let the car idle until the oil temp is ~105 as read by the AP(idle drops around this time as well), then drive gently until oil temp is around 180.

 

Oil temp is more important.

I always let the car idle for 1 minute before pulling away. The first 30 seconds contributes to the highest engine wear.

Engine speed not to exceed 3000 rpm before coolant is fully warm

Engine speed not to exceed 4000 rpm before oil is fully warm.

It's a moot point anyway since I rarely exceed 3000rpm anyway.

Good grief, really?
I suppose I used to be easier on my cars...my BRZ (and my bugeye when I owned it) sees 5-6000rpms, daily. Some day I'll be dead.

 

I paid close attention to my oil temp this morning. It didn't hit 180 until about 11.5 miles into my 22 mile drive (18F outside). I'm still in my break-in period so it's not a big deal, but I don't see myself staying under 3k RPM or even 4k RPM after break-in that long to wait for the temps to get up to optimal.

 

I Always warm up the car. both of our cars have remote start buttons. so i can turn it on while enjoying my coffee before work. when i got outside? the engine temp is just below regular running temp, the exhaust note sounds right, and the inside of the car is toasty warm.

BTW: @XJman, -5 to-20 degrees Celsius on my island, no Dramas with the oil on cold starts. actually starts better than our Leggy with lower mileage and thinner oil.

 

Rule of thumb: oil takes 2x longer to reach operating temperature compared to coolant.

How are you guys getting oil temp? I don't think it's an option on my GR.

 

2015MY+ has it available on the center console triple meter.

For what its worth I let it warm up for about a minute, then accelerate gently until the temp gauge has been in the normal range for a at least a few minutes.

Near or below zero degrees F more warm up and even less demand on the right pedal.

 

Yesterday the lowest overnight temperature in my area was around 5°. My garage is not heated. I was pouring some Rotella 15W-40 (a great oil, at a terrific price BTW) into an engine and by that time it must have been around 10°-15°, no more. The oil was visibly viscous and poured very differently to the way I'd expected.

I think Subaru and everyone else are right to go as "thin" as possible. Not only does this save fuel over the entire fleet but it seems to allow better cold pumping, plus it seems to transfer heat during use better than the more viscous oils of yesteryear. For my particular applications a 15W-40 HD diesel oil is fine, but any colder (say, below 0° overnight) and I really do suspect a 5W-40 synth would have provided better cold startup flow.

That said, I only warm up carburreted engines because I have to. If it's fuel injected I'm driving away in it.
