Warm up procedure?
Hi, I was just wondering how long people give it from staring the engine from cold to pulling away.
My usual drill is to start the car, roll a roll up(disgusting habit, I know) to pass the time and wait until the Temp needle starts to move. I then drive without going above 2000 rpm until the needle has passed the quarter marker and then I drive the normal way again.
It is usually about 3-5 minutes before I even touch the accelerator. It gets a bit tedious now and then and I am very tempted by a remote start but don't wanna spend the money.
So, how long do you leave it?

Start, wait 30s and drive off boost and no more than 2-3k rpm until the engine has warmed up (at least 10 minutes), then gradually increase revs up to 4k if needs be.
You do more harm than good sitting in a stationary car letting it idle, besides as others have said it is transmission fluids that need to warm up as well.

you are best off letting it find its feet for 10seconds and then pulling away, than letting it idle for minutes, it is better for the car. but drive really slowly with lots of mechanical sympathy untill the oil temps creep up to a working temp.
Also get an oil pressure guage. It can be scary how long it takes from a cold start to get pressure when you can see it!
I pre pressure the oil system before starting. But I have big power forged engines in mine. So might be a bit over the top for a daily driver.

I get in, Start the car then put my seat belt on. Clip Phone in and connect lead then drive off. 20 second tops maybe. Rev limits are irrelevant too, just stay off boost.
I have an oil pressure gauge and get 95-100psi instantly. Then again I use 0W50 Fully Synthetic oil so I should.
I do remember watching a friend start his 1.0l Fiesta ohv engine many years ago with the rocker cover off. It took 30 seconds before there was any sign of a trickle of brown sludge over the rockers......
Your Tyres, brakes and diffs need to warm up just as much as the engine. Driving off right away gives the whole car a chance to warm together, which can only be good mechanically.
Once I see oil temp after maybe 5 mins, I'm good to go. Water takes a little less time.
My previous toy had limits of -40 to +80 degrees for oil. The oil cooler was bigger than the Scooby's Intercooler and used fuel to cool the oil/heat the fuel then a secondary air vent for further cooling. We could set take off power with temps above 0' That's 4,500shaft horsepower and the oil was fine.

No you're all doing it wrong.
Get in drive straight away and redline it and keep it in same gear till the limiter kicks in and it's warm then. If anything flys out of exhaust, don't worry it's just all the dust and crap that was sleeping in it night before.
Happy to help.

This subject has come up a few time.Where did the idea come from that Subaru engines are made from antique fragile glass?
What a load of nonsense.It's just an engine.Same as any other car.Please tell me if you have definitive information why a Subaru engine should be treated differently from any other engine.
Turn it on and drive it carefully until up to temp. Same as I have done with every other car I have owned.

I think the main concern is that the main and big end bearings are not as wide as on a straight engine.

I only asked as I'm new to impreza. From now on I'll be getting in, starting up, rolling the roll up and then driving off, taking it easy for the first 5 minutes or so. If you don't ask, you don't learn. Cheers fellas.

Too many people think they have an F1 engine round here.
Get in and drive with sympathy until the oil is up to temp then let it go.
Let's have a conversation about Turbo timers next and the ridiculous rules of use surrounding them

On cold days such as this and especially if the car hasnt been driven the day before or sometimes even a week I start her up and let it idle for at least 5 mins. If i dont and start the car and start driving as soon as i get out the drive the car stalls and then have to churn the key to get her to start again which i dont think is healthy.
Starting the car and letting it idle for couple minutes is annoying at times but hey thats the unfortunate joy of owning a turbo and doing things right.

No - it's just causing more damage and is doing things wrong!
If your car stalls if you drive straight away suggests there is something wrong with your car or there is issue with your driving

I just get in and drive straight away, i keep off boost until i see decent oil temp which takes a really long time. To see 70 degrees i'm usually a good 5 or more miles down the express way and to see full operating temp of 90+ i'll be getting on for 10 miles away!
I see people do the start and leave it for 5 mins thing with motorbikes too, no idea why you'd be far better of riding around slowly getting brakes and tyres up to temp than leaving it idling for ages and then ragging it off into the distance.

As mentioned a few times above, a no-load idle situation is not brilliant for an engine, there is far less strain and load on components at a few thousnad revs, this is why when you put new cams in or re build an engine you should never let it idle on first start up.

I suspect its the idle control valve or something but like I said I dont mind warming it up whilst it is parked in the garage to get temps up which works perfectly for me. I then at first take a steady drive to get the tyres, brakes warm before running ragid. Yeah right!

I drain the oil into a roasting dish, put in a pre heated oven at 100ēc (90ēc if its fan assisted) for 10 mins then pour back into car, start engine, maximum launch out of drive. Lol

Are we talking about steam trains or cars? Granted early cars did need warming up carefully due to poor oils, poor tolerances on engines etc but todays cars whatever make or model don't need treating with kids gloves.
