"Always warmed up and cooled down"

Warming up improves the viscosity of the motor oil, thus reduces premature engine wear. Moreover, the engine needs warming up to let the pistons and piston rings expand to normal size. I was expecting this was common sense.
Re cooling down: turbo wheels normally use a simple friction bearing which is lubricated by engine oil. If one was to park his cat with a sizzling red glowing hot turbo bits of oil remaining in the bearing will end up charred and build up residues which eventually will lead to premature turbo failure

No but on UK Turbo 2000's there is a sticker on the drivers door which states after heavy highway driving you should allow the engine to idle for one minute before turning off. I think they mean a long hard blast to a sudden stop like a petrol station. It doesn't say why but Subaru wouldn't go to the trouble of making the sticker and then sticking it right in the drivers view for no reason.
I have done about 60,000miles over 7 years in my scoob and always let it warm up about a minute before setting off and mostly let it idle a minute before turning off. Unless I come home late at night when I coast down the hill towards my house (yes bad for car control etc) but does the same job and stops the neighbours being woken up. Probably all over kill but why not.

No such sticker on my newage but you should always do what the manufacture says.Cooling down or running down like others here has never been an issue. I cant boost on the resident streets by my house, plus by the time i have revered onto my drive, swapped sunglasses for specs ect its had the time to cool off. Petrol stations is a point to consider though. I never really drive on boost for any period of time. Squirt and giggle is about it.

I bet the fuel used with turbo timer running time would be more than enough to buy a new turbo over the non run down turbo life span

and drive very slowly with mechanical sympathy untill the oil temperatures begin to rise. A oil temp guage is a good bit of kit as it shows you when you get to a proper operating temperature ...unlike the crude water temp guages found in most cars.Oil presure at start up is also another subject to delve into perhaps.....
