For example, during the winter months, metal can heat slowly but cool rapidly and during the summer months when it is 100 F , prolonged heat, excessive temps can be bad for the seals/ gaskets.

Does my question make sense? I am a not an engineer so please enlighten me.

Thanks.

It shouldnt matter since your motor temp/oil temp is the same once the cars warmed up, whether its summer or winter. And, if you keep the car under 4k rpms like Porsche recommends, theres barely any strain on the motor anyway. Theres guys that have run full races on days over 100 degrees without any problems at all so you should be ok.

 

Let me say that this reply falls under Noob leading the Noob.

I think that as long as your oil temp is around 200 it shouldn't make too much difference what the outside temp is.

 

Vic - your car is liquid cooled in order to maintain consistant engine temps no matter the outside temp. New engine break-in is important to "seat" moving parts that are in contact with other parts (valves / seats - rings / cylinders etc...) The idea is to heat cycle these parts has they "mate" with each other... back in this old days this was more important than today... but it's still important...

To go back to the original question - 'Is there a good reason to break in our cars'? Err.... yes, because Porsche tells us to! They designed the engine and transmission and certainly know more about them than any of us. If they say it needs breaking in, it needs breaking in!!!

 

Ian,

Actually, the question was "is there a good season to break in our cars" Personally, I don't think ambient temperature is as important as the operating temperature of the component that is wearing in. YMMV

Dang it. I forgot I am driving a water cooled Porsche!

 

what about all those studies or people getting the car and nailling it from beginning and gets broken in how its gona be driven...also people take their car to the dyno and nail it there...also porsche dealership told me to nail it from start...and that the engines that are driven soft (by bev hills moms or grandpa) they dont wana buy back
