Yah this is true, However I just got back from england and I had a peice of CRAP 97 Rover 600. (it's basically a honda accord with a 200hp turbo in a HUGE heavy body and bad suspension.) It used engine oil to cool down the turbo and it stated that if the turbo was used in any frequency to wait 5-10 minutes letting the turbo cool down before turning off the car! Man that sucked ass.To warm up the engine just start and go but drive easy until up to normal operating temperature.
There is no need to warm up or cool down the turbo. Safeguards have been engineered into all turbo cars for many years.
Well multiple people said at the dealer that you don't have to worry about that because of the synthetic oil they've been using now...whatever that means but Craten is right. When I shut off my engine in my garage I hear a buzzing noise and I always wondered what it was but it sounds like it must be that oil circulator Craten is talking about. The buzzing stops after a few mins. Go ahead, listen for it next time.I know that the '07 GTI comes with a built-in oil circulator that will run after the engine is shut off to keep it from fryin' in the turbo. There's no need to worry about letting it run or having a turbo timer installed. Granted that letting the rest of the machine cool down after runnin' it hard would be a good idea, don't worry 'bout da' turbo fryin' on ya'. O0
