I live in FL, so it usually warms up pretty quick... I let it idle until its almost warmed up all the way...

the only time i really warm it up for like 10 mins is if im scraping ice and snow off of the car so it defrosts. im the kind of person that refuses to drive until all the snow and ice is removed from the car. i cant stand when other people dont do that. other than that, if its below freezing, ill let it run for abour 2-5 mins just to get the oil flowing a little better before taking off.

I smoke a cig( 2 to 5 minutes) then im rollin.... even at low temps the 4 cylinder heats up extremely fast. 1 minutes probably plenty. Dont forget the one minute cool down before shut off

I warm it up until the temp needle starts moving out of the "IT'S SRSLY TOO COLD OUT, BRO" area.

in my OPINION cars warm up in 2 stages...

my initial warm up procedure is just wait till the needle moves and then I get going. In the summer this happens pretty quick, wintertime maybe 5 to 7 minutes. from there I drive the car with keeping the load very light and shifting below 3k.

the 2nd stage is when you can drive the hell out of it if you so choose to do so. Again this happens much faster in summer than winter but I like to see my oil get about the 160F mark before I even think about getting into boost or driving my subie more aggressively.

I drove to work the other day and kept track in my head of how long it took my oil to get up to temp. It was 36 degrees outside and during 12 mile, 25 minute city driving comute with very light traffic my oil temp gauge barley lifted off its lowest value of 140F

I've seen guys who think that water temp gauge on the dash is like some sort of meter that tells you when you can beat on your car but imo its all about oil temp!

Watch those bearings BRAH!

There is actually more strain on engine internals if you let it idle for 10 minutes than letting it idle for 45 seconds and then letting it warm up to 180 degrees while driving under 2500k the whole time. The more time the engine is cold, the more wear in internals - letting it idle for ten minutes may warm up the coolant a bit on a cold start, but even when the thermostat starts to open, the oil still isn't at operating temperatures.

I try to put it in gear and rev-match the gauge needle sweep. Is that too soon?!

LOL what? I wouldn't warm up my car more than 5 minutes if it was -40C up here and anything close to freezing 1 minute max. Waste of gas and sensless engine wear idling the car for that long.

Isn't it ironic the people that let their car idle for long periods in attempting to baby the car are the ones doing the most damage opposed to people that just start and drive?

what viscosity do you run? that's what determines whether an oil is suitable in winter or not (so I've read anyway)

Rotella T6 5w40. From the website:

Shell Rotella« T6 5W-40 provides excellent low-temperature flow, even at -30║F.

Start it up and drive away. The only time I let it warm up is when there is ice on the windshield. I start the car and let it idle for the couple minutes it takes to scrape it.

(opinion on wrx 5mt only)
Also, transmission fluid takes longer to warm up still and we all know how strong our 5mts are. It's dumb to see significant amounts of boost/engine load for the first couple minutes
(opinion on EJ205/07 only)
Wouldn't be surprised if a significant amount of bearing failures are in part due to people running the piss out of their cold, old blocks, which could cause shear and stress on the bearings and when they really spin, could be well after the engine has warmed-up and the warm-up factor is not even considered. Then again I'm not a fan of the 2.0.

Exactly this. I definitely don't flog it until the engine is fully warm, though, usually at least 15 minutes depending on the temperature.
