How long do you let your car warm up?

Trips

Your poll is like a build a burger. Lol

Idle until water temp gets to ~110F and RPMs drop to ~1050. Keep RPMs below 2500-3000 until oil temp moves off the peg. Keep RPMs below 3500-4000 until oil at 160F. WOT when oil temp gets to 175-180F.

I'm not sure how that fits into your poll.

Either wait for water to move off the bottom or let the juices flow then drive like a granny

I ignore the dash water temp gauge (it's even more worthless than the fuel gauge). I use my ScanGuageII to monitor water temp.
The main thing I'm looking for is RPMs to drop before moving. After that, oil temp is what I'm looking at.

What exactly does "let the juices flow" mean?
I do drive like a granny until the oil temp comes up.

Welllll... What I mean is you just let the oil lube up the top half of the engine

Exactly. Once the choke comes off, we're just about good to go. I trust the engine mgmt system. Not that I could fight a case of cracked rings or hairline cracks in the cylinder walls with the dealership, but manufacturers 'generally' test the engines and program the CPU to act accordingly.

The choke in my car is only engaged for... 30-45 seconds, then the RPMs drop
And the garage is... 60-ish degrees

I'm pretty sure that my procedure is overkill for most cars built in the last decade or two. Modern engines are a lot tougher and have a much stronger sense of self-preservation than the "classics" I'm used to driving and working on. I wouldn't want to cold start and then immediately do a WOT 1/4-mile, but merging onto the freeway when cold (I live in S AR so my "cold" is pretty warm compared to what some of you see in Winter, plus I have a 1 mile cruise through the neighborhood before getting to a freeway) shouldn't be all that hard on a modern engine.

I do somewhat the same, oil temp dictates when I can be naughtier with the throttle. Plus I don't want the cold oil to cause excessive oil pressure (read somewhere our engine oil bump max at 100 psi or something?)
