Turning off car prior to car reaching proper operational temp- long run issues?
Hello,
I have a question about turning off the car before the car reaches proper temperature. As I live about 1km from the gotrain and walking is not an option (don't ask ). Sometimes I have time to circle the area and run laps before I turn off the car, but not often. I heard this is one of the worst things we can do to engines as the moisture (or carbon build up?) within the engine created don't have a chance to burn off and thus creates rust or issues within the engine. Is this a legitiment concern with new engines, this being a thing of the past? Last edited by c416; 01-21-2013 at 02:31 PM.. |

I'm going to tag along as well to this question.
I know that if your ripping it and you turn your car off right away you destroy your turbos because they don't have a chance to cool down they basically stop and fry themself. |

Not a bad idea to do a long drive about once a week to burn off excess moisture in the engine.
I used to commute 5 mins to a go train everyday, but I would do a nice drive 1 a week to stretch the cars legs and burn off any moisture. |

In theory thats a slight possibility butt you cant take everything you read literally. If that was the case there would be fried turbos everywhere. They get cooled...I've never heard of this happening to anyone. |

I had a 2002 BMW 325i that i drove for a very short commute time in -20c to 0c. That resulted in a $2000 repair bill for a $70 dollar part.
To keep it short, as your engine warms it creates condensation = (cold block + combustion heat). When you reach optimal operating temperature, a valve opens PCV or CCV in a BMW and allows this moisture to be circulated into the combustion chamber, Viola no moisture in your oil. But when you don't reach optimal temperature each time your creating moisture in the motor and engine oil. Since oil change intervals are so long you get a high moisture content. When that moisture surrounds a rubber membrane = CCV valve and freezes it tears and clogs that valve. Go to e46 look up CCV valve, so look under your engine oil cap white film = moisture! |

I think that this question came up somewhere else on this forum as well. I am in the same boat, I drive 2.2 km to get to work. However, I take a longer 15-20 km drive on the way home everyday. But, I do idle in the Tim Horton's drive through line in the morning, so my 325 does reach normal operating temperature. Regardless, short, cold trips are not well received from our cars

I reach 50 degrees oil temp after 20 mins of driving conservatively, especially in this recent weather
