I'm very religious about letting my 92T warm up and cool down. but today I was thinking... I'm just guessing how long the car needs, without knowing if I'm right or not. correct me if i'm wrong, but the point of warming up is to let the oil reach normal operating temperature so the turbo isn't damaged when boosting. what if I were to install an oil temperature gauge by the turbo, so I would know exactly when I'm ready to boost in the morning? and if this works, also monitoring oil temp during cool down so I can avoid running the engine longer than necessary? would this work? has anyone tried it?
