Maintaining turbo

Hi,
I've heard conflicting reports of how best to maintain the turbo's life on an 850. Should I be letting the car idle for a period of time after driving? Do I need to idle at all? Idle only after driving for a set amount of time or speed? Or what? Thanks.

Good/frequently changed oil, and let the car idle for 5-10 sec before turning it off.

Does idling really help? I can't say for sure, but if you do it 7 days/week, at worst you're wasting a paltry few minutes per month.

If it does help, you're doing something that takes 0 effort.

I do it.

Synthetic oil is extremely important to run in turbocharged cars. I have a turbo timer installed on my car to let it idle after it runs. It has been proven that letting the car idle for at least 30 seconds after a hard or long run is crucial for maintaining the turbo's life. 15 seconds is probably safe for easy driving and a not very long trip. Otherwise, oil cokes up in the turbo lines and next time the car starts, the bearings will be forced to operate without lubrication, which is very bad for it.
